Sound Level Measurements
How is Sound Measured? | Noisy Planet
We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels.
How do you measure noise levels? - Commodious
The decibel scale measures noise logarithmically, which is similar to how our ears perceive sound, so a sound 10 times more powerful than 0 dB is 10 dB, a sound ...
Decibel Scale - measure the different levels of sound - SoundEar Int.
This scale is known as the decibel scale and uses units called decibels (dB). Simply put, the greater the decibel level, the louder the sound.

What Is A Sound Level Meter? - HBK
A sound level meter is designed to respond to sound in the same way as the human ear and to give reproducible measurements of sound pressure levels (SPL).
What is a decibel and what does it measure? - Healthy Hearing
Decibels measure sound intensity (amplitude). Sound is energy that travels in waves. It can be measured in two ways: frequency and amplitude.
Sound Level Measurements - NTi Audio
The Sound Pressure Level (SPL) is the most basic level used in sound measurements. The SPL, measured in Decibels (dB), has been widely used since the 1930s.
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power ...
