, Masking sound effect: 'acoustic effect defined as the existence of a noise which on account of its level and frequency completely or partly erases another weaker noise. This effect, which is easily demonstrated using measuring devices, is less frequent from a physiological point of view due to the higher differential sensitivity of the ear, p.66

, The notion of reverberation is linked to a defi of measurement: the time taken for the sound to decrease by 60 decibels. If the baseline sound enters into a particular acoustic relation with the background noise, Propagation effect, by which some frequencies resonate for a short time, but long enough for the discrepancy between the direct wave and the reflected wave to be audible, p.111
