  2. Reverberation mapping - Wikipedia

    en.wikipedia.org/wiki/Reverberation_mapping

    Light from the accretion disk around a supermassive black hole is scattered off the surrounding broad line region, causing a delayed echo at redder wavelengths. Reverberation mapping (or Echo mapping) is an astrophysical technique for measuring the structure of the broad-line region (BLR) around a supermassive black hole at the center of an ...

    English: Very simplified diagram: sound level in a reverberant cavity excited by a pulse, as a function of time. RT60 is the reverberation time. The small variations (small vertical peaks) of the pressure along the lines are not shown.

    After determining the best dimensions of the room, using the modal density criteria, the next step is to find the correct reverberation time. 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.

  5. Reverberation - Wikipedia

    en.wikipedia.org/wiki/Reverberation

    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 ...

    The natural reverberation and echo from the hard walls of the echo chamber gave Spector's productions their distinctive quality and resulted in a rich, complex sound that, when played on AM radio, had a texture rarely heard in musical recordings. Jeff Barry said: "Phil used his own formula for echo, and some overtone arrangements with the strings."

  9. Sound reinforcement system - Wikipedia

    en.wikipedia.org/wiki/Sound_reinforcement_system

    Digital effects units may offer multiple pre-set and variable reverb, echo and related effects. Digital loudspeaker management systems offer sound engineers digital delay (to ensure speakers are in sync with each other), limiting, crossover functions, EQ filters, compression and other functions in a single rack-mountable unit.
