Understanding Decibels And Noise Levels

Decibels measure sound intensity, and portable generator noise levels are usually measured in decibels to determine how loud they can be.

What Is A Decibel?

A decibel, often abbreviated as dB, is a unit of measurement used to quantify sound intensity. It’s based on a logarithmic scale that represents the ratio between two sound pressure levels or power levels.

To put it into perspective, consider that normal conversation usually occurs at around 60 decibels, while a whisper measures at about 30 decibels. When shopping for a portable generator, understanding its noise levels measured in decibels becomes vital because you wouldn’t want one that creates disturbances or discomfort due to excessive noise.

How Is Noise Measured?

Noise levels, including those of portable generators, are measured in units called decibels (dB). Decibels represent a logarithmic scale that quantifies the intensity of sound waves relative to each other.

Professionals typically use a specialized device known as a sound level meter or decibel meter to measure the noise level of a portable generator. This instrument picks up and measures the intensity of sound waves in your immediate environment.

For example, when assessing generator noise levels for comparison purposes, measurements are often taken at ¼ load from 7 meters away – specified as dB(A) at ¼ load at 7 meters.

This standard measurement helps ensure consistency and accuracy across generator models and brands like Briggs & Stratton’s PowerSmart Series™ and Honda EU2200iTAG.
