✦ Synopsis

S UMMA RY

Though computer-generated low crest-factor signals can now be produced and processed to derive the impulse response of auditoria, the use of impulsive signals remains the simplest and, in many cases, a fully viable technique. The advantages of a uni-polar half-cycle sine wave test signal are discussed and compared with those of the hi-polar single-cycle signal The particular requirements for visual display of the impulse response are reviewed, as are the signal requirements and analysis options for objective measures involving integrated energy. In each case the implications are considered of interference between reflections which arrive simultaneously.
