A transient testing technique has been developed for rapid testing of components of acoustic systems. Transient pressure data are digitized, recorded and utilized in frequency-domain to provide the dynamic characteristics of the system. The idea behind the method is to make use of the sampled time data of a sound source and two microphones measuring the pressure at two locations in a steel pipe attached to the component of the acoustic system. The analysis procedure is based on the construction of a mathematical model for the system from the experimental response data. Experiments were conducted for many acoustic components of various geometrical configurations such as partition pipes and expansion chambers and excellent agreement between experimental and theoretical results is illustrated. The proposed approach is applicable to field testing situations where short duration testing with a minimum of portable equipments is desi-rable and no special requirements such as anechoic terminations are available.
