A lawn mower is a common household tool that is used to maintain the length and appearance of a yard’s grass. They come in various types such as push, electric, and gas. Lawn mowers can be loud and noisy, creating hearing problems especially if the machine is not functioning correctly or the operator is not wearing protective gear. So, how many decibels is a lawn mower?
First, let’s define what a decibel is. A decibel is a unit of measurement that provides information about the intensity of a sound. Sound is measured in decibels (dB). The decibel is a logarithmic unit of measurement, meaning that an increase or decrease of 3 dB represents a doubling or halving of the sound level, respectively.
The decibel level of a lawn mower depends on the type and manufacturer of the machine. According to the Occupational Safety and Health Administration (OSHA), the maximum permissible noise exposure over an eight-hour workday is 90 A-weighted decibels (dBA). Any noise level above 90 dBA is considered dangerous and can cause permanent hearing loss if exposed to it for an extended period.
According to research, a gas-powered lawn mower can produce up to 106 dB of noise, which is significantly higher than the 90 dBA limit set by OSHA. Conversely, electric and push lawn mowers are quieter and emit around 75 to 85 dB of noise. It’s essential to note that a lawnmower’s decibel level can be affected by several factors, such as the age of the machine, maintenance, and the surrounding area’s noise level.
To protect your hearing while operating a lawn mower, it’s recommendable to use ear protection. They can reduce the incoming sound by 15-30 dB, which can enhance a person’s comfort and security while mowing. They come in various types, including earplugs, earmuffs, and noise-canceling headphones. An operator should also be aware of the machine’s emissions and perform regular maintenance to prevent unnecessary noise.
In conclusion, a lawn mower can generate considerable noise, especially gas-powered mowers, which can produce up to 106 dB. It’s crucial to protect yourself whenever you work with or around lawn mowers. The operator should ensure that their equipment is functioning appropriately, maintain it regularly, and wear proper hearing protection.

How many decibels does a lawn mower produce?
The number of decibels produced by a lawn mower depends on the type and size of the mower. Generally, a typical gas-powered lawn mower produces around 90 to 100 decibels of sound, while an electric lawn mower produces around 75 to 85 decibels.
Is the noise produced by a lawn mower harmful to our hearing?
Yes, the noise produced by a lawn mower can be harmful to our hearing if we are exposed to it for a prolonged period. A sound level of 85 decibels or higher can cause hearing damage if we are exposed to it for more than eight hours.
How can we protect ourselves from the noise produced by a lawn mower?
To protect ourselves from the noise produced by a lawn mower, we can wear earplugs or earmuffs while operating the lawn mower. It is also advisable to limit the amount of time we spend near the lawn mower and take breaks in between to rest our ears.
