Acoustics
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 low amplitudes are ...
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 dissimilar, the cross ...
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 mounted in aircraft ...
stochastic
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 calibration.
artificial mouth
Science; Acoustics
Device consisting of a loudspeaker unit mounted in a baffle or an enclosure so shaped as to have a radiation pattern similar to that of the average human mouth.
