Acoustics

Fourier analysis tells us that time and frequency are simply two alternative ways of observing a signal. By changing the nature of a signal in the time domain, we implicitly change the nature of the ...

ultrasound

Science; Acoustics

Frequencies above the audible range, that is over 20 kHz.

exponential averaging

Science; Acoustics

Generates a continuous running average where the most recently sampled spectra have more influence on the average than older samples. This provides a convenient form to examine changing data with the ...

audiogram

Science; Acoustics

Graph showing hearing loss as a function of frequency, measured with an audiometer.

peak frequency-weighted sound pressure level

Science; Acoustics

Greatest instantaneous value of a standard frequency weighted sound pressure level, within a stated time interval. Note: If frequency weighting is not specified, the A-frequency weighting is ...

peak sound level

Science; Acoustics

Greatest instantaneous value of a standard frequency weighted sound pressure level, within a stated time interval. Note: If frequency weighting is not specified, the A-frequency weighting is ...

haas effect

Science; Acoustics

If the sound from a specific source arrives at one ear a few milliseconds later, than the other ear, then our hearing mechanism will judge the sound to be coming from the side of the head where the ...
