You may wonder how many db is a chain saw? The answer to that question depends on several factors. In this article, we’ll look at the types of chainsaws, the noise levels they produce, and how to reduce the noise. Chainsaws typically emit 106 decibels, but there are also electric and gas models available that are significantly quieter. While they don’t reduce noise by more than 15 decibels, the vibration they create causes hand-arm injuries, including carpal tunnel syndrome.
A 106 dB chainsaw is louder than most snowmobiles, jets, and even a symphony orchestra. But what exactly makes a chainsaw so loud? Let’s compare its noise to other loud noises in our environment, and figure out how loud these are at a distance of one foot. For reference, a jet engine reaches 120 dB at 30 meters, and a Vuvuzela horn can be heard at one foot.
Electric chainsaws are quieter
An electric chainsaw has many advantages over gas-powered counterparts. Compared to their gas-powered counterparts, they are lighter and quieter. Electric chainsaws are also easier to start, and the only thing you need to power them up is an outlet and extension cord. Additionally, they require less maintenance than gas-powered ones. Generally, maintenance is easier on electric chainsaws, but they still need regular oil changes.
Earmuffs reduce noise by 15 to 30 dB
The effectiveness of ear muffs for chainsaw use can be attributed to their ability to block out noise, which reduces the risk of hearing damage by up to fifteen decibels. While ear muffs can significantly reduce the noise level, they are not very comfortable for most people. Moreover, they are only effective when worn for a limited period of time. The duration of noise exposure determines how much damage is caused by loud sounds.
Hand-arm vibration causes carpal tunnel syndrome
The decibel level of a chainsaw is about 90 dB at a 1-foot distance. The sound intensity decreases with distance as the inverse square law is applied. At 30 feet, the noise level is comparable to the sound produced by a group of people talking over the phone. In addition, a chainsaw can cause severe injuries to the hand, which can include carpal-tunnel syndrome.
Adding a second muffler to a chainsaw reduces noise output
A chainsaw’s mufflers reduce the noise output by limiting the amount of air that enters the engine and allowing air to escape. The size of the muffler opening depends on the cylinder and barrel exhaust port sizes. Generally, a saw’s opening can be up to 1.5 times the cylinder exhaust port. A chainsaw must maintain back pressure in the exhaust system, or it will suck up metal particles, and this causes the engine to burn up.
