logarithmic amplitude scale
Science; Acoustics
Critical vibration components usually occur at low amplitudes compared to the rotational frequency vibration. These components are not revealed on a linear amplitude scale because ...
cross-correlation
Science; Acoustics
Cross-correlation is a measure of the similarity of two time domain signals. If the signals are identical, the cross correlation will be one, and if they are completely ...
personal noise exposure
Science; Acoustics
Daily personal noise exposure or weekly personal noise exposure.
pressure microphone
Science; Acoustics
Designed to measure the pressure that exists in front of the microphone diaphragm as opposed to the common free-field microphone. Used to measure the pressure in cavities or flush ...

Science; Acoustics
Details of individual events may be unpredictable but the overall character of the sound is. For example rain falling, sound of insects, birds etc.
electrostatic actuator
Science; Acoustics
Device comprising an auxiliary electrode that permits the application of an electrostatic force to the metallic or metalized diaphragm of a microphone in order to obtain a ...
artificial mouth
Science; Acoustics
