Reverberation time (RT) is the time required for the sound in a room to decay over a specific dynamic range, usually taken to be 60 dB, when a source is suddenly interrupted. The Sabine formula relates the RT to the properties of the room. (59)T=0.161V/αS where V is the volume ...
The reverberation time in the cavity of a double-leaf wall system is affected by both the sound absorption material placed within the cavity and the coupling that occurs between the cavity and the leafs. The reverberation time is described theoretically for the case of coupling between the cavity...
Sound is a mechanical wave which travels through a medium from one location to another. This motion through a medium occurs as one particle of the medium interacts with its neighboring particle, transmitting the mechanical motion and corresponding energy to it. This transport of mechanical energy th...
The method of the present invention for generating a simulated reverberation signal having a plurality of output channels comprises receiving an audio input signal having a plurality of channels wherein each channel transmits time-synchronized audio data elements representative of the audio sound upon wh...
This depth is typically chosen to coincide with the depth\nwhere the first scattering or reflection occurs for the reverberation noise one\nintends to suppress. The beams realized with post-processing show energy\ndecrease at the chosen depth, especially for shallow depths where in a medical\n...
Sound WavesSonarScatteringSimulationReverberation or scatter echo occurs during an active detection. Bats have to deal with this form of interference, and process it in order to detect and identify their targets. Reverberation can be studied by simulation, by shaking bushes in an anechoic chamber. ...
For the active option of a moving underwater vehicle, the Doppler shift occurs during such two processes: sound wave incident from the platform to the scatter and scattering back to the platform. Considering the scattering field comes from multiple directions of the seafloor, the received ...
STFT reflects the frequency change in the signal over time at standard frequencies and is one of the most commonly used features for sound classification. The basic idea of STFT is to truncate the signal in the time domain by a window function and treat the signal in the window as a smooth...
Therefore, to evaluate the sound absorption performance of the specimen surface more accurately, it is necessary to investigate a measurement method to quantitatively determine whether sufficient diffusion occurs in the reverberation chamber. Previous studies on the diffuse field in the reverberation chamber...
