Frequency: Frequency is the range of sounds (low to high) that a sound level meter can hear. The human ear, for instance, can hear frequencies from 20 to 20,000 hertz (Hz).

Therefore, if the measured sound level on the C network is much higher than that on the A network, much of the sound energy is concentrated in the low frequency region (see INFRASONIC). Since the A ...

Frequency: Frequency is the range of sounds (low to high) that a sound level meter can hear. The human ear, for instance, can hear frequencies from 20 to 20,000 hertz (Hz).

The term most often used in measuring the magnitude of sound. It is a relative quantity in that it is the ratio between the actual SOUND PRESSURE and a fixed reference pressure. This reference ...
