How Many Decibels is a Lawn Mower

In most neighborhoods, push lawnmower and mowing vehicles resemble engines cutting across the air. Can riding lawnmowers be loud?


The answer depends on a variety of factors. It covers typical noise and decibel levels used when riding a lawn mower and how they can decrease the noise and potential dangers that come from using them.

In addition, we’ll discuss safety precautions for the usage of the lawnmower in accordance with a local noise ordinance. Typical gasoline-driven lawnmowers reach decibel levels of 88 to 100 psi.

What is an acceptable (dB) noise level?

The acceptable noise level varies depending on the context and individual sensitivity to noise. For residential areas during the day, acceptable levels are generally 70 dB or lower, while 45 dB or lower is recommended at night. In industrial or commercial areas, noise levels can be higher, and in certain contexts like concerts or sporting events, they can be much higher without harm.

Determining acceptable noise levels is crucial for occupational safety since prolonged exposure to high levels of noise can lead to health problems like hearing loss, cardiovascular disease, and cognitive impairment. Therefore, acceptable noise levels need to be established for different contexts and individuals to minimize the risk of such health problems.

According to the World Health Organization (WHO), the recommended maximum exposure level to noise for an 8-hour workday is 85 dB. However, for residential areas, noise levels of 70 dB or lower during the day and 45 dB or lower at night are considered acceptable to prevent health issues.

Maximum exposure limit

  • 85 dB for an 8-hour workday
  • 88 dB for a 4-hour workday
  • 91 dB for a 2-hour workday
  • 94 dB for a 1-hour workday
  • 97 dB for a 30-minute workday
  • 100 dB for a 15-minute workday

Noise exposure can increase the risk of depression and anxiety.

What Is A Decibel And What Does It Measure?

The decibel (dB) is a standard unit used for measuring sound intensity. The dB scale is logarithmic, which means that an increase of 10dB represents a sound that is ten times louder.

Why Are Riding LawnMowers So Loud?

Riding lawnmowers are louder than push mowers due to several reasons, including larger and more powerful engines, higher blade speeds, amplified noise by the metal deck and vibration, and inadequate sound insulation or mufflers.
