This paperaddressesthe problemof loudspeak er test. Two applicationsare investigated:loudspeak er manufacturingfault detection and maintenance.In order to comply with practical requirements,we proposea new, brief, nonstationarytest signal. Recordedloudspeak er responsesareprocessedusinganimproved time-frequenc y decisionalgorithm. Thefault detectionprocedure is testedwith real data. Resultsshow its accuracy andpractical interest.
