Variable speaker distance is therefore the most important degree of freedom when deploying idealized layouts in actual rooms. It is constrained by the reverberation of the room which leads to uneven direct-to-reverb ratios between speakers at different distances, and the power handling capability of the most distant speaker.
All multi-driver speakers (unless they are coaxial) are difficult to measure correctly if the measuring microphone is placed close to the loudspeaker and slightly above or below the optimum axis because the different path length from two drivers producing the same frequency leads to phase cancellation. It is useful to remember that, as a rule ...
Speech Transmission Index (STI) is a measure of speech transmission quality. The absolute measurement of speech intelligibility is a complex science. The STI measures some physical characteristics of a transmission channel (a room, electro-acoustic equipment, telephone line, etc.), and expresses the ability of the channel to carry across the characteristics of a speech signal.
The measure of the low frequency (many tens of Hz) noise contributed by the turntable of an analogue playback system. It is caused by imperfect bearings, uneven motor windings, vibrations in driving bands in some turntables, room vibrations (e.g., from traffic) that is transmitted by the turntable mounting and so to the phono cartridge.
Microsoft Word allows creating both layout and content templates. A layout template is a style guide for the file styles. It usually contains a chapter which explains how to use the styles within the documents. A content template is a document which provides a table of contents. It might be modified to correspond to the user's needs.

Required for measuring the acoustics in buildings is a signal generator that provides pink or white noise through an amplifier and omnidirectional speakers. In fact, the omnidirectional speaker, or sound source, should provide an equal dispersion of sound throughout the room. To achieve accurate measurements, sound should radiate evenly.
