(decibel chart) why do we use decibel (db)? what is decibel? decibel is the unit of sound. its symbol is ‘db’. we can define decibel as a unit of measurement used to express the ratio of one value of a power or field quantity to another on a logarithmic scale, the logarithmic ...
How Is Sound Measured? To measure the intensity (noise level) of a sound, we use a measurement unit called a decibel (dB). Quite simply, the louder the sound, the higher the decibel number. What Is a Decibel Chart? A decibel chart shows the intensity levels of common environmental sou...
