Abstract
A large data base over values of various room acoustic parameters
has provided the basis for statistical analyses of how and how
much the acoustic properties of conert halls are influenced by
their size, shape and absorption area (as deduced from measured
reverberation time). The data have been collected over a fifteen
year period from about fifty concert halls in Europe and the US.
In all halls the same measurement technique was used (1/1 octave
sweep tones all pass filtered to form impulse responses per octave
band). Due to the large range of geometric differences contained
in the material, it has been possible to derive empirical
regression formulae from which the influence of certain
geometrical design variables can be quantified. The author has
found these fairly simple relationships useful in teaching and as
guide lines both in the early stages of physical hall design and
in setting up electronic reverberation enhancement systems.
