AB  - As a conclusion to previous work, cepstral analysis is applied to electroacoustic measurements in order to deconvolve room reflections and obtain an anechoic (free-field) result from measurements taken in a reverberant environment. Theoretical limitations of the cepstrum in dealing with bandpass systems are discussed and it is seen that room deconvolution is complicated by the inherent low-frequency high-pass nature of the loudspeaker itself. The phase nature of room reflections is also discussed and it is shown that minimum-phase behavior is still exhibited at the relatively large measurement distances and the modest time window lengths required for adequate low-frequency measurements. This minimum-phase behavior of room reflections helps to simplify the deconvolution process.
