title: VISAUDIO: a Windows software application for Bekesy audiogram analysis and hearing research.
abstract: A Windows software system has been designed to facilitate hearing research programs and decision aid for epidemiological surveys in a military context. VISAUDIO provides graphical displays of audiograms with the results of various processing (smoothing, pathological patterns detection and classification), audiograms with pathological patterns like scotoms and recruitments are described (number, impaired frequencies, severity of loss for scotoms). Classical French ORL indexes are calculated (Index 42 which is the French legal index in occupational medicine, PAM or Lafon's index, IPA from the French norm NF S31-013 and IRB, a new occupational medicine index). An audiometric pattern classification is done for each audiogram using discriminant factorial analysis. The program allows audiogram comparisons on the same screen. The processing and analysis results can also be copied to any Windows software package via a PC clipboard. This prototype software is to be tested in a quasi real-time audiological information system comprising audiogram acquisition, processing, analysis and storage in a database. VISAUDIO software functions are illustrated with examples of screen displays.
