Reverberation time as distinct from the reverberation period, described above, is defined as the length of time for the output to reach a set percentage of the input to the reverberation unit and is dependent upon both the reverberation period, T, and the gain A' of the amplifier 26. It ...
The reverberation time of the enclosure is defined as the time required for the sound pressure level to fall 60 dB. Thus, the well-known Eyring equation [2], which gives the reverberation time T for an energy drop of 60 dB, is obtained from Eq. (10.47), with S = Stot = ∑Si, whe...
The beam cross-correlation (BCC) is defined as the cross-correlation between the beamforming output and the observed multi-channel signal, which carries an approximation of the room impulse response. Adopting covariance matrix of BCC matrix as the DNN input to enable explicit characterization of ...
IT IS NOT ADVISABLE TO GO THROUGH AIRPORT CUSTOMS OR INTO SCHOOL BUILDINGS ETC. WITH A STARTER PISTOL IN YOUR HAND / LUGGAGE. A starter pistol is an impulsive sound source. An impulsive sound is defined as an almost instantaneous (thus impulse-like) sharp sound such as a clap, pop or a...
In LDA, a linear subspace is constructed in which the selected materials are most separated from one another. We defined the contribution of an acoustic feature as the sum of square of the loadings of the feature in the subspace divided by the dimension of the subspace (12). $${C}_{f}...
