A prototype software program was developed to combine the speed and flexibility associated with MLV with the standardization of recorded word lists. The sound quality of 20 personal computers was evaluated for total harmonic distortion plus noise (THD+N). The computers with the poorest sound quality were then used to replace the recorded speech sources of two clinical audiometers and tested for compliance with ANSI standard s3.36-1996. Of the 20 computers evaluated, only one had sound quality too poor to qualify for clinical use under the ANSI standard. These findings suggest the sound quality of most personal computers is adequate for clinical use, and future computer-based presentation methods for word recognition testing could provide an attractive alternative to traditional methods.application/pdfviii, 100 pagesengCopyright protected, all rights reserved.Audiology -- Computer programsSpeech therapy -- Computer programsText
