Acoustics

random vibration

Science; Acoustics

A vibration whose instantaneous amplitude is not specified at any instant of time.

asymmetric

Science; Acoustics

A waveform not identical on both sides of the mean or zero line, lacks symmetry.

A-weighted, equivalent sound level (Laeq)

Science; Acoustics

A widely used noise parameter describing an sound level with the same energy content as the varying acoustic signal measured. Also written as dBA Leq.

transfer function

Science; Acoustics

Acoustic signals are modified by any structure or medium they encounter. If for example you can measure the input to a vibration isolation mount and simultaneously measure the output, then the ...

All audio systems are limited by inherent noise at low levels and by overload distortion at high levels. The usable region between these two extremes is the dynamic range of the system. Expressed in ...

RMS averaging

Science; Acoustics

Also called power spectrum averaging, calculates the weighted average of the sum of the squared levels. The weighting is either linear or exponential. RMS averaging reduces random fluctuations in the ...
