How Loud is A Chainsaw, in Decibels?
As the roar of a chainsaw fills the air, it’s hard not to feel a sense of awe at the power and capability of this tool. But while it may be impressive, the noise it produces can be dangerous, causing permanent hearing damage and leading to a lifetime of regret. Understanding how loud a chainsaw really is and the decibel levels that require hearing protection is essential for anyone working with power tools. In this article, we’ll explore the true impact of chainsaw noise and how you can protect yourself from its harmful effects.
Chainsaws are incredibly useful tools for cutting down trees and pruning branches. However, they can also be quite loud, so it’s important to take proper precautions to protect your hearing.
The loudness of a chainsaw is measured in decibels (dB), which is a unit of measurement for sound intensity. A typical gas-powered chainsaw can produce between 100-120 dB, while an electric chainsaw produces around 90 dB. At around 85 dB our ears can be damaged with extended exposure above 85dB, which means that you should never use a gas chainsaw without hearing protection — but a lot of homeowners do precisely that.
It’s important to note that the actual sound level produced by a chainsaw can vary depending on a number of factors, such as the size and type of chainsaw, the type of wood being cut, and even the technique used by the person cutting. For example, cutting through thick hardwood will produce a louder sound than cutting through softwood.
As for the different power sources, gas-powered chainsaws are generally the loudest, followed by corded electric chainsaws, and then battery-powered chainsaws. This is because gas-powered chainsaws use internal combustion engines, which are inherently noisy. Electric chainsaws, on the other hand, use a motor to power the chain, which is generally quieter.

Prolonged exposure to high noise levels can cause permanent hearing damage, so it’s important to take proper precautions when using a chainsaw. This may include wearing earplugs or noise-canceling earmuffs and taking regular breaks to give your ears a rest.
Chainsaws are quite loud due to how they operate, with gas-powered chainsaws producing between 100-120 dB and electric chainsaws producing around 90 dB. The actual sound level produced can vary depending on a number of factors, such as the type of chainsaw and the type of wood being cut. When using a chainsaw, it’s important to take proper precautions to protect your hearing and avoid permanent damage.
Why are chainsaws so loud?
Chainsaws are loud because of the way they operate. The saw chain, which rotates at high speed, cuts through the wood by making thousands of small, rapid cuts per second. These cuts cause vibrations and friction in the chainsaw’s engine, which in turn generate noise.
In addition to the cutting action, the chainsaw’s engine and exhaust system also produce noise. The combustion engine in gas-powered chainsaws uses a series of explosions to create the energy needed to power the saw. These explosions, along with the exhaust system, contribute to the overall noise level of the chainsaw.
While some manufacturers have made efforts to design quieter chainsaws, it can be difficult to balance the need for power and cutting ability with noise reduction. Quieter chainsaws may have less power, slower cutting speeds, or other trade-offs that can affect their performance.
However, technological advances have led to the development of quieter electric and battery-powered chainsaws. These types of chainsaws have lower noise levels because they don’t use combustion engines and don’t produce as much vibration as gas-powered chainsaws. In addition, noise-reducing features such as anti-vibration systems and noise-dampening materials can be added to chainsaw designs to help reduce noise levels.
When Should you Wear Hearing Protection?
The intelligent time to wear hearing protection is when you are exposed to noise levels above 85 decibels for an extended period of time. Any exposure to noise levels above 85 decibels can cause hearing damage over time, so it’s important to take precautions to prevent hearing loss.
The duration of exposure to loud noise is also a factor to consider when deciding to wear hearing protection. If you are going to be exposed to loud noise for a short period, such as 30 seconds or a few minutes, it may not be necessary to wear hearing protection. However, if you are going to be exposed to loud noise for an hour or longer, it’s important to wear hearing protection.
Examples of situations where hearing protection may be necessary include attending a concert, working in a noisy factory or construction site, operating power tools, or riding a motorcycle or snowmobile. In these situations, the noise levels are typically above 85 decibels and can cause hearing damage over time.
If you care about your hearing and want to avoid any damage, it’s recommended to wear hearing protection when exposed to noise levels above 85 decibels. The longer you are exposed to loud noise, the higher the risk of hearing damage. It’s important to note that even a short exposure to loud noise can cause hearing damage, so it’s best to err on the side of caution and wear hearing protection whenever possible.
In summary, the intelligent time to wear hearing protection is when you are exposed to noise levels above 85 decibels for an extended period of time. The duration of exposure is also a factor to consider, and it’s recommended to wear hearing protection for an hour or longer. It’s essential to take precautions to prevent hearing damage and consult with a hearing specialist to determine the most suitable type of hearing protection for your needs.
When it comes to dB level and hearing protection, it’s important to note that any exposure to noise levels above 85 decibels can lead to hearing loss over time. It’s recommended to wear hearing protection in noisy environments, such as construction sites, factories, or concerts, to prevent hearing damage.
Regarding the safest time to start using hearing protection, it’s best to start as early as possible to avoid any damage to the ears. Even a short exposure to loud noise levels can have a negative impact on hearing, so it’s essential to take precautions as soon as you notice any discomfort.
Foam earplugs are a popular and affordable option for hearing protection. They can be easily inserted into the ear canal, and they come in different shapes and sizes. However, it’s important to note that not all foam earplugs fit well for every ear size and shape. When selecting foam earplugs, it’s important to consider the noise reduction rating (NRR), which indicates how much noise the earplugs can reduce. The higher the NRR, the more effective the earplugs are in reducing noise exposure.
Earmuffs cover the entire ear and provide more consistent noise reduction than earplugs. They are typically used in situations where noise levels are high, such as in industrial or construction settings. Earmuffs are also more comfortable for individuals who may experience discomfort or irritation from earplugs.
Custom-molded earplugs are designed to fit the individual’s ear, providing a secure and comfortable fit. These earplugs are often made by taking an impression of the individual’s ear and creating a mold that is unique to the person’s ear canal. Custom-molded earplugs are ideal for individuals who work in noisy environments for extended periods. They are also more durable and can be reused multiple times.
Selecting the appropriate hearing protection depends on individual preferences and circumstances. Foam earplugs are a good option for short-term use and are easy to use, while earmuffs are more suitable for individuals working in loud environments for extended periods. Custom-molded earplugs provide the highest level of comfort and noise reduction, but they require more investment. It’s essential to consult with a hearing specialist to determine the most suitable type of hearing protection for your needs.

How Loud Noises Can Damage our Health
Exposure to high levels of noise can have a negative impact on a person’s health, and the effects can be both physical and psychological. According to the World Health Organization, prolonged exposure to noise levels above 85 decibels (dB) can cause hearing loss, and exposure to noise levels above 100 dB can cause hearing damage after only 15 minutes.
In addition to hearing damage, exposure to noise levels above 85 dB can lead to other physical health problems such as high blood pressure, heart disease, and respiratory problems. These health effects can occur even if a person is not directly exposed to the noise, but rather is exposed to it indirectly over time.
There are also psychological health effects associated with exposure to high levels of noise. These can include anxiety, depression, and sleep disturbances. Noise pollution can also negatively impact productivity, communication, and quality of life.
It’s important to note that the severity of the health effects is related to the intensity and duration of the exposure to the noise. The longer a person is exposed to high levels of noise, the greater the risk of negative health effects. Additionally, certain individuals may be more sensitive to noise and may experience negative health effects at lower levels of exposure.
In order to protect against the negative health effects of noise exposure, it’s recommended to wear hearing protection such as earplugs or earmuffs when in noisy environments. It’s also important to limit exposure to noise levels above 85 dB and take breaks from noisy environments whenever possible.
What Noise Levels are Considered Normal?
Let’s define what we mean by “normal sounds.” Normal sounds are those that are not harmful to our hearing when we are exposed to them for a reasonable amount of time. Examples of normal sounds include conversation at a normal volume, bird songs, and the sound of leaves rustling in the wind.
On the other hand, sounds that are too loud can be harmful to our hearing. Harmful sounds are those that are loud enough to cause damage to our ears or hearing. Examples of harmful sounds include a chainsaw, a rock concert, and a firework explosion.
The loudness of a sound is measured in decibels (dB). Generally speaking, sounds over 85 dB can cause hearing damage if you are exposed to them for a prolonged period of time. To give you an idea of what this means, here are some familiar sounds and their approximate decibel levels:
Here’s a chart of various sounds and their corresponding decibel levels, from loudest to softest:
- Jet engine at 100’ – 140 decibels (dB)
- Pain Begins – 125 dB
- Rock concert: 120 dB
- Pneumatic chipper at ear – 120 dB
- Chainsaw at 3’ – 110 dB
- Power mower – 107 dB
- Subway train at 200’ – 95 dB
- Walkman on 5/10 – 94 dB
- Level at which sustained exposure may result in hearing loss – 80-90 dB
- City Traffic – 85 dB
- Telephone dial tone – 80 dB
- Chamber music, in a small auditorium – 75-85 dB
- Vacuum cleaner – 75 dB
- Normal conversation – 60-70 dB
- Business Office – 60-65 dB
- Household refrigerator – 55 dB
- Suburban area at night – 40 dB
- Whisper – 25 dB
- Quiet natural area with no wind – 20 dB
- Threshold of hearing – 0 dB
As you can see, a chainsaw is a particularly loud sound, with a level of approximately 100 dB. This means that if you are exposed to the sound of a chainsaw for a prolonged period of time, it can cause hearing damage.
As you can see, sounds like jet engines and pneumatic chippers are very loud and can cause hearing damage if you’re exposed to them for a long time. On the other hand, sounds like normal conversation and household appliances are much quieter and less likely to cause hearing damage. It’s important to protect your hearing when you’re exposed to loud noises for long periods of time, like wearing earplugs or earmuffs.
The amount of time that you can be exposed to a sound before it becomes harmful depends on the loudness of the sound. As a general rule, the louder the sound, the less time you can be exposed to it before it becomes harmful. Here is a rough guideline:
- 85 dB: 8 hours
- 90 dB: 2 hours
- 95 dB: 1 hour
- 100 dB: 15 minutes
- 105 dB: 7.5 minutes
- 110 dB: 3.75 minutes
- 115 dB: 1.875 minutes
So, if you were to be exposed to the sound of a chainsaw (approximately 100 dB) for more than 15 minutes, it could potentially cause hearing damage. It’s important to protect your ears from loud sounds by using earplugs or other hearing protection.
Noise Level Studies: Chainsaw Loudness
In a recent study, researchers conducted a noise level analysis on the Stihl MS 250 chainsaw during the felling of black pine trees. The study found that the average noise level during the pre-operation and post-operation stages was less than 80 dBA, which is considered manageable with simple precautions to prevent negative effects on human health. However, during the undercut stage, the average noise level was measured at 95.35 dBA, exceeding the hazard limit of 90 dBA, and during the back cut stage, the average noise level was measured at 86.73 dBA, exceeding the warning limit of 85 dBA. These high noise levels can lead to significant hearing loss problems from a lifetime of exposure, as well as other health issues such as high blood pressure, heart diseases, respiratory issues, and psychological problems for chainsaw operators.
To mitigate the impact of noise on workers, the study recommends the use of ear protection equipment during felling operations. Additionally, work should be interrupted during work hours to prevent permanent damage to chainsaw operators. Overall, this study highlights the importance of understanding the potential health risks associated with chainsaw operations and taking appropriate measures to protect workers from excessive noise exposure.
Chainsaws are a staple tool in the logging industry, but with concerns over emissions and noise levels, researchers have been looking at alternative options. This study focused on the Echo ECCS-58V battery-powered chainsaw and its viability compared to the traditional gas Dolmar PS 5000 chainsaw during commercial thinning.
The study involved seven separate tests, measuring variables such as working time, working area, and noise load. The researchers then calculated the average productivity, equivalent continuous sound pressure level (LAeq), and noise exposure level (LEX, 8h) normalized to an 8-hour working day.
Surprisingly, the battery-powered chainsaw held its own against the gas chainsaw, with an average working time of 41 minutes and 26 seconds compared to the gas chainsaw’s average working time of 41 minutes and 41 seconds. However, the gas chainsaw had a higher work output of 100 square meters per hour.
The real standout feature of the battery-powered chainsaw was its lower noise exposure levels, LAeq, and LEX,8h. It also had lower workloads due to the smaller noise levels and zero emissions. This makes it a more environmentally friendly option, and could potentially be a game-changer in the logging industry.
The study concluded that battery-powered chainsaws are effective tools for commercial thinning. However, further tests should be conducted to determine the impact of low temperatures on battery consumption. It’s an exciting time for the industry, as we explore new ways to make logging more sustainable and efficient.
This study focused on measuring noise levels during different stages of tree felling using a power chainsaw. The findings revealed a wide range of noise levels, ranging from 115.72 dBA to 51.65 dB, depending on the stage of cutting and the moisture content of the wood. The mean noise levels measured near the operator’s ear ranged from 95.19 dBA to 101.10 dB and decreased with increasing distance from the source of the noise. The study highlights the need for power saw operators to use hearing protection, as noise exposure above 85 dBA can lead to health problems such as ringing in the ears and anxiety. Additionally, the study recommends that manufacturers should focus on reducing noise levels in future power saw designs.
The use of chainsaws can be hazardous not only due to the sharpness of the saw blades but also because of the noise and vibrations they produce. A recent study investigated the impact of different factors on the magnitude of noise and vibrations produced by chainsaws, such as the type of drive, electric versus combustion.
The results showed that the chainsaw with a combustion engine produced higher sound level pressure compared to the electric chainsaw. The difference in sound level pressure between the two chainsaws tested was most noticeable in the octave band with the center frequency of 125 Hz, where the combustion chainsaw produced a value 19.8 dB higher than the electric chainsaw.
The study also examined the perceptions of chainsaw operators and non-chainsaw operators towards the noise emitted by chainsaws. Both groups showed a similar trend: the higher the sound intensity, the more it was considered noisy and disturbing. Using earplugs or earmuffs can reduce the perceived loudness of the noise, but earmuffs tend to be more effective than earplugs in reducing noise pressure. However, earmuffs can be uncomfortable to wear for prolonged periods in hot environments and can interfere with the use of other protective equipment such as goggles.
The study recommends the use of personal protective equipment (PPE) such as anti-vibration gloves, earmuffs, and earplugs to protect operators and bystanders from the noise and vibrations produced by chainsaws. The type of ear protection device used may depend on the individual’s comfort level and the noise level produced by the chainsaw. Earmuffs are typically used for protection up to 110 dB, while earplugs are used for protection up to 100 dB.
It is important to note that there are differences in the perception of chainsaw noise between chainsaw operators and non-chainsaw operators. Different individuals may react differently to the same stimulus or circumstances. This is known as “perceived loudness,” and we discuss it in the next section.
The point is, it’s crucial to monitor the use of ear protection devices and educate individuals on the proper fitting and use of PPE. By taking these steps, the hazards associated with using chainsaws can be minimized, ensuring a safer work environment for operators and bystanders alike.
Psychoacoustics is a scientific term that refers to the psychology of hearing, or rather, how humans perceive sound. It refers to how loud a sound is experienced by a listener and how it affects them. Human perception of sound is determined by the physical characteristics of the sound, as well as the listener’s individual hearing ability and other factors such as context and personal preferences. The loudness of a sound is generally measured in decibels (dB), which is a logarithmic scale that expresses the intensity of a sound relative to a reference level.
The perceived loudness of a sound is not solely determined by its physical intensity, measured in dB. The human ear is more sensitive to sounds in certain frequency ranges, and the perceived loudness of a sound is influenced by its frequency content. The equal loudness contours, also known as Fletcher-Munson curves, illustrate how the ear perceives loudness at different frequencies. These curves show that at low frequencies, sounds need to be more intense to be perceived as equally loud as sounds at higher frequencies.
Electric chainsaws produce a different frequency spectrum of sound than gas-powered chainsaws due to the differences in their motors. Electric chainsaws typically produce more high-frequency noise, which can be perceived as louder even if the sound intensity is similar to that of a gas-powered chainsaw. The frequency range of the sound can also affect how the sound travels and is absorbed by different materials, which can impact the overall noise level in different environments.
Other factors that can affect perceived loudness include the duration of the sound, the ambient noise level, and the individual hearing ability of the listener. Prolonged exposure to loud sounds, including those produced by chainsaws, can also cause hearing damage and contribute to other negative health effects.
Perceived loudness is influenced by the physical characteristics of a sound, including its intensity and frequency, as well as individual factors such as hearing ability and context. Electric chainsaws may be perceived as louder due to the higher frequency content of their sound, even if the sound intensity is similar to that of a gas-powered chainsaw. It is important to consider both the physical intensity of the sound and its frequency content when assessing and mitigating the potential impacts of noise on human health and well-being.
Being exposed to loud noises for too long can harm your hearing and overall well-being. Using earplugs and earmuffs can help keep you safe from the risks of loud noises. Knowing how sound frequency affects perceived loudness can help us all stay protected from the negative effects of chainsaws and other power tools.
Will Chainsaws Ever be Quiet?
While it’s possible that chainsaw manufacturers may continue to improve and develop technology to reduce the noise levels of chainsaws, it’s unlikely that they will ever be completely silent. The noise produced by a chainsaw is primarily due to the rapid mechanical movement of the chain, which generates a significant amount of sound.
However, there are already some chainsaws on the market that are designed to produce less noise than traditional chainsaws. These chainsaws typically incorporate noise-reducing features, such as vibration-dampening and sound-absorbing materials.
One example of a relatively quiet chainsaw is the STIHL MSA 220 C-B. This battery-powered chainsaw produces significantly less noise than a traditional gasoline-powered chainsaw and is designed for use in noise-sensitive environments.
The reason why chainsaws haven’t been made completely silent is due to the trade-off between noise reduction and cutting power. In order to reduce noise, the chainsaw may need to operate at a lower power level, which would reduce its cutting ability. Additionally, the noise-reducing technology may add to the cost of the chainsaw, making it less accessible to consumers.
In summary, while there are chainsaws on the market that are designed to produce less noise than traditional chainsaws, it’s unlikely that they will ever be completely silent due to the mechanical nature of their operation. However, with continued development and research, manufacturers may be able to reduce noise levels while maintaining cutting power and affordability.

Protect your Hearing from Chainsaws, and any Loud Noises
Hearing loss is a grave and disconcerting issue that affects millions of people around the world. Regrettably, once hearing has been damaged, it is often irreversible, particularly when it results from exposure to loud noises. The sensory cells within the inner ear that are responsible for detecting sound waves do not regenerate, rendering the hearing loss permanent and distressing.
Individuals who work in noisy environments, such as loggers, are at a heightened risk of hearing loss if they fail to take appropriate precautions. According to the Centers for Disease Control and Prevention (CDC), the prevalence of hearing loss among loggers is greater than in many other occupations. However, the use of adequate hearing protection can significantly diminish the likelihood of hearing loss.
Loggers can protect themselves from hearing loss by using appropriate hearing protection, such as earmuffs or earplugs. It is imperative to use hearing protection that is commensurate with the level of noise exposure in the work environment. Regular hearing check-ups with an audiologist can also help detect hearing loss early and prevent it from exacerbating over time.
It is also possible to mitigate the risk of hearing loss by taking steps to reduce noise levels in the work environment. For example, logging equipment can be fitted with noise-reducing mufflers, and maintenance procedures can be observed to ensure that equipment operates smoothly and quietly.
The Occupational Safety and Health Administration (OSHA) recommends that employers provide hearing protection to employees who are exposed to noise levels above 85 decibels for an extended period of time. For noise levels between 85 and 90 decibels, employers should offer a range of hearing protection options, including earplugs or earmuffs. For noise levels above 90 decibels, OSHA mandates that employees use hearing protection, such as earplugs or earmuffs.
Homeowners who utilize power tools or chainsaws should also use hearing protection if the noise levels exceed 85 decibels. Foam earplugs or earmuffs are practical and effective options for reducing noise exposure. Earplugs are inexpensive, portable, and convenient, while earmuffs offer a more consistent level of noise reduction and are more comfortable for extended use.
To optimize the efficacy of hearing protection, it is essential to ensure that it is worn properly. For earplugs, it is imperative to insert them correctly and check for a proper fit. For earmuffs, it is crucial to adjust them properly to ensure that they cover the entire ear and create an airtight seal.
In conclusion, hearing loss caused by loud noises is often irreversible. However, the risk of hearing loss can be significantly reduced by utilizing appropriate hearing protection and noise-reducing measures in the work environment. Regular hearing check-ups with an audiologist are also critical for early detection and prevention of hearing loss. Employers and homeowners should adhere to OSHA guidelines for providing and using hearing protection to ensure that the risk of hearing loss is minimized.
