Abstract : A variety of laboratory procedures have been used to measure human response to aircraft noise during the development of the effective perceived noise level (EPNL) concept. Evaluation of these procedures to determine their effectiveness would be useful in further refinements of EPNL. This report describes a project to demonstrate how four of the laboratory methods can be tested and the results used to provide a comparative evaluation. The general conclusion is that experimental plans for four basic psychoacoustic laboratory methods have been demonstrated. The report describes some tentative findings that are interesting and significant in the context of the demonstrated examples. (Author)
