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."
The first reverb effects, introduced in the 1930s, were created by playing recordings through loudspeakers in reverberating spaces and recording the sound. [2] The American producer Bill Putnam is credited for the first artistic use of artificial reverb in music, on the 1947 song "Peg o' My Heart" by the Harmonicats.
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.
Acoustic enhancement is a subtle type of sound reinforcement system used to augment direct, reflected, or reverberant sound. While sound reinforcement systems are usually used to increase the sound level of the sound source (like a person speaking into a microphone, or musical instruments in a pop ensemble), acoustic enhancement systems are typically used to increase the acoustic energy in the ...
To capture these sound waves, scientists successfully filmed the crystal sample with extremely high precision, as the wave only exists within the crystal for one-millionth of a second.
For example, in architectural acoustics the rectilinear trajectories of sound rays make it possible to determine reverberation time in a very simple way. The operation of fathometers and hydrolocators is based on measurements of the time required for sound rays to travel to a reflecting object and back. The ray concept is used in designing ...
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.
