Comparison of concert hall measurements of spatial impression
Journal of the Acoustical Society of America, 96:3525-3535.
Two different types of measures of spatial impression, lateral energy fractions and interaural cross correlations, were measured at a number of locations in 14 different concert halls. The mean and range of the hall‐average values of these quantities give an indication of typical conditions to be expected in other larger concert halls. Comparisons of hall‐average values of the two types of quantities showed them to be significantly related at medium and lower frequencies in good agreement with theoretical expectations. Individual position measurements were less well related and showed that other factors had a major influence on the individual position measurements. In some halls the two types of quantities varied quite differently with increasing source–receiver distance. At a particular seat location, the two types of measures cannot always give similar indications of expected spatial impression. Calculating hall‐average values from a small number of measurement locations is shown to introduce significant errors.
