real time frequency analysis
Science; Acoustics
Measurement of octave or third octave band noise where all the filters are measured simultaneously, ensures no loss of data.
cross power spectrum
Science; Acoustics
Measurement of two signals with an amplitude that is the product of the two signal amplitudes and a phase that is the difference of the two phases.
moment of momentum
Science; Acoustics
Measures and objects tendency to spin, units - kilogram meter squared per second - kg·m 2 /s
omni-directional microphone
Science; Acoustics
Measures sound energy arriving from all directions equally. In order to comply with the standard requirements measurement microphones are omnidirectional unless otherwise stated. ...
traffic noise index (TNI)
Science; Acoustics
Method developed in the 1970's based on the LA10 and LA90 measured figures in the formulae. TNI = 4 (LA10 - LA90) + (LA90 - 30) dB.
