Abstract

An overview is given on an approximate statistical comparison of the results obtained by a direct hemi-anechoic method versus a reference reverberant method for a consumer product, namely a conventional household refrigerator-freezer. The statistical validity is limited by the sample size of six. The data indicates that the range of values of the 1-meter equivalent sound levels is comparable for both measurement methods, and that there is a slight bias (lower) for the direct hemi-anechoic method.
