Reverberation time is a measure of the time required for the sound to "fade away" in an enclosed area after the source of the sound has stopped. When it comes to accurately measuring reverberation time with a meter, the term T 60 [ 6 ] (an abbreviation for reverberation time 60 dB) is used.
In a reverberant space, the sound perceived by a listener is a combination of direct and reverberant sound. The ratio of direct sound is dependent on the distance between the source and the listener, and upon the reverberation time in [the room]. At a certain distance the two will be equal. This is called the "critical distance."
A reverb effect, or reverb, is an audio effect applied to a sound signal to simulate reverberation. [1] It may be created through physical means, such as echo chambers , or electronically through audio signal processing .
The most appropriate reverberation time depends on the use of the room. RT60 is a measure of reverberation time. [9] Times about 1.5 to 2 seconds are needed for opera theaters and concert halls. For broadcasting and recording studios and conference rooms, values under one second are frequently used. The recommended reverberation time is always ...
How well a room absorbs sound is quantified by the effective absorption area of the walls, also named total absorption area. This is calculated using its dimensions and the absorption coefficients of the walls. [4] The total absorption is expressed in Sabins and is useful in, for instance, determining the reverberation time of auditoria.
Diffusion, in architectural acoustics, is the spreading of sound energy evenly in a given environment. A perfectly diffusive sound space is one in which the reverberation time is the same at any listening position. Most interior spaces are non-diffusive; the reverberation time is considerably different around the room.
The basic purpose of such chambers is to add colour and depth to the original sound, and to simulate the rich natural reverberation that is a feature of large concert halls. The development of artificial echo and reverberation chambers was important for sound recording because of the limitations of early recording systems.
reverb. The echoing sound that occurs naturally to a voice or instrument in hall or room with reflective walls and, by extension, to analog or digital effect units which recreate this effect (reverb units). Rhodes. The Fender Rhodes brand of electric piano, and, by extension, to similar instruments produced by other manufacturers. rig
