Reverberation (commonly shortened to reverb), in acoustics, is a persistence of sound after it is produced. [1] Reverberation is created when a sound or signal is reflected. This causes numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and ...
Reverberation is the persistence of sound caused by repeated boundary reflections after the source of the sound stops. This principle is particularly important in enclosed spaces. Diffraction is the bending of sound waves around surfaces in the path of the wave.
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 .
It changes the disturbing echo of the sound into a mild reverb which decays over time. Diffraction is the change of a sound wave's propagation to avoid obstacles. According to Huygens’ principle, when a sound wave is partially blocked by an obstacle, the remaining part that gets through acts as a source of secondary waves. [17]
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer .

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."
Dereverberation is the process by which the effects of reverberation are removed from sound, after such reverberant sound has been picked up by microphones. Dereverberation is a subtopic of acoustic digital signal processing and is most commonly applied to speech but also has relevance in some aspects of music processing.
