3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Decay curve
Describes the pattern of decay of sound pressure levels over time in a room after the sound source stops sounding.
[GB/T 20247-2006, Definition 3.1]
Note 1. The decay curve can be measured either after continuous noise interruption in the room or by inverse integration of the impulse response.
Note 2. It is not recommended to directly use the curve obtained by the non-continuous sound source to accurately measure the reverberation time of the room (for example, using a starting gun as a sound source, recording with sound level)
The instrument is recorded. This method can only be used for investigative simple-level measurements. Usually the room impulse response is not simply exponentially decaying, its slope is
The results obtained from the integral of the impulse response are not the same.
3.2 Interrupted sound source method
A method of obtaining a decay curve by directly recording the decay of the sound pressure level after an excitation of a broadband or narrowband sound source in the room to interrupt the sound.
[GB/T 20247-2006, definition 3.3]
3.3 Impulse response integration method
The method of obtaining the decay curve by integrating the inverse of the square of the impulse response against time.
[GB/T 20247-2006, definition 3.4]
3.4 Impulse response
The time-varying sound pressure formed by the Dirac pulse emitted from one point in the room at another point.
