Abstract
The paper examines and discusses possible explanations of the
systematic deviations between conventional and intensity-based
sound transmission loss measurements frequently reported in the
literature. Both the conventional diffuse-field method and the
method based on the sound intensity technique are subject to
several systematic errors of comparable size. The sources of error
include non-linear decay functions, the absorption of the
partition itself, and intensity measurement errors, which are
aggravated by the fact that the sound field conditions are usually
fairly difficult. It is concluded that with very careful
measurement procedures there are no systematic deviations.
