A reverberation sound producing apparatus is disclosed which has an input terminal supplied with audio frequency signals, filters for dividing the audio frequency signals applied to the input terminal into a plurality of frequency bands, delay lines for delaying output signals from the filters by ...
the desirable property of auditoriums is to such an extent that it facilitates the overcoming of the sound intensity’s inverse square law dropoff in the enclosure. However, in case it is excessive, the sound would become muddy.
Reverberation Time values vary in different positions within a room. Therefore, an average reading is most often taken across the space being measured. Visualization of the basic principle of a Reverberation Time Measurement. Rooms with a reverberation time of < 0.3 seconds are called acoustically "...
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 ...

Some Theoretical Observations Concerning the Reverberation Time for the Case of a Harmonic Emitting Sourceis the absorption energy from the air; in last three relations the symbol w represent the volume density energy.For the deduction of the expression of the absorption energy in air, we con- ...
To infer the still not well known structure of the inner region of Active Galactic Nuclei (AGN), it is of great importance to measure the size of the closely related line emitting region, the Broad-Line Region (BLR), estimating super-massive black hole masses, and determining physical conditi...
The effects of summing the modes coherently or incoherently and of including the time spreading due to the modal group velocities are examined. This paper deals with the range‐independent monostatic case, although the technique is extendible to bistatic geometries and range‐dependent environments. ...
and development progress and viewpoints of NetEase Yunxin in speech de-reverberation and improvement of communication effects, focusing on the solution based on adaptive combination of dual-mic signal correlation. The overall goal is to improve de-reverberation in the case of fidelity speech. Effect....
