Calculation of acoustic impedance of multi-layer absorbers
I.P. Dunn,W.A. Davern +1 more
TL;DR: In this paper, a method of calculating the overall acoustic impedance of multiple layered absorbing systems is presented, and good agreement between measured (impedance tube) and computed impedances has been obtained.
Journal ArticleDOI
The statistical bandwidth of Butterworth filters
John L. Davy,I.P. Dunn +1 more
TL;DR: In this paper, it was shown theoretically that the ratio of statistical bandwidth to effective bandwidth for an nth order Butterworth band pass filter is 2n (2n−1).
Journal ArticleDOI
The Effect of Moving Microphones and Rotating Diffusers on the Variance of Decay Rate
John L. Davy,I.P. Dunn +1 more
TL;DR: In this article, the authors investigated the use of moving microphones and rotating diffusers to reduce the uncertainty of decay rate or reverberation time measurements in a reverberant room and showed that in most situations, the ensemble variance of the decay rate obtained with stationary microphones and diffusers is not affected by either a moving microphone or a rotating diffuser.
