Abstract
In this paper we examine the practical aspects of measuring the impulse response of a tubular acoustic system, taking into account thermal and viscous attenuation. Though good approximations for the frequency response of such a system exist for the continuous time and frequency case, we show that transforming these approximations to the discrete time domain is not trivial. We show how the discrete impulse response can be calculated theoretically using methods derived from digital filter design, and compare the theoretical calculations to experimental results. The comparison shows an improvement in the agreement between theoretical and experimental results, in comparison to previously published results..
