Encyclopedia > Concert Hall Acoustics
It has been suggested that this article or section be merged with Acoustics. (Discuss)

The study of architectural acoustics originated with Wallace Clement Sabine. In 1900, the Symphony Hall, Boston was the first concert hall in the world which was specially designed by Sabine according to scientific acoustic principles, based largely on reverberation time. Prior to Sabine, the creation of great sounding concert halls was more a matter of luck than good design. Now concert hall acoustics is a recognised specialised area of acoustics which straddles architecture, engineering and physics. Wikipedia does not have an article with this exact name. ... Acoustics is a branch of physics and is the study of sound, mechanical waves in gases, liquids, and solids. ... Architectural acoustics is the science of controlling quality of sound in buildings. ... Wallace Clement Sabine (June 13, 1868 - January 10, 1919) was an American physicist who founded the field of architectural acoustics. ... Symphony Hall in Boston, Massachusetts is widely considered to be one of the two or three finest concert halls in the world, alongside Amsterdams Concertgebouw and Viennas Grosser Musikvereinssaal. ...


Desirable acoustic properties of halls that sound pleasing to the ear can be measured and replicated by acoustic engineers.


Important parameters include:

  • reverberation time (RT)
  • early decay time (EDT)
  • clarity index (C80, C50)
  • definition (D50)
  • initial time delay gap (ITDG)
  • bass ratio (BR)
  • strength factor (G)
  • interaural cross-correlation coefficient (IACC)
  • apparent source width (ASW)
  • listener envelopment (LEV)
  • lateral energy fraction (LEF)
  • balanced noise criteria (NC)
  • room criteria (RC)

Reverberation time is a measurement used in acoustic design. ...

CONCERT HALL ACOUSTICS (5533 words)
In a concert hall, the important point to remember is that the volume of reflected sound should not be loud enough to be consciously heard, even when the tensions of the body have relaxed and the listener is hearing very loudly.
Anyone familiar with the acoustic of such a room will understand that reverberation should be treated as a basically undesirable element to be held to low limits, and not as a toy to be played with for various effects, as is often the case with reverberation devices in sound-reproduction.
A hall's acoustic is "bright" when an unequal transmission of the frequency spectrum favors the higher frequencies, i.e., in traveling from the stage to the listener, the balance of the higher to the lower frequencies changes, the higher frequencies becoming louder in proportion to the lower frequencies.
