Acoustic diffraction analysis by the impulse response method: A line impulse response approach

The Journal of the Acoustical Society of America, 1984
Acoustic diffraction of plane impulsive waves is considered for free-field, baffled, and pressure release boundary conditions, in the case of an arbitrary spatial distribution of combined, amplitude-time delay modulation in an aperture. The method is based on the impulse response analysis of parallel aperture lines, the line impulse responses being ...

Some spatial analysis of the room impulse response

Journal of the Acoustical Society of America, 2015
The room impulse response (RIR) and measures derived from it have been a powerful tool for room characterization. Traditionally, these measures are based on time domain characteristics like reverberation time or clarity. By recoding a group of RIRs with microphone arrays, one can add the spatial dimension to the RIR.

Self-similar analysis of the room impulse response

The Journal of the Acoustical Society of America, 2006
Important information of the room acoustic characteristics is contained in the room impulse response. We analyze the time-space correlation of the impulse response by the self-similarity method. The room impulse response is divided into the frame of the length of the fixed time. Attractors are composed by affine transformation of each frame.
