Audiometric data to be used

The hearing threshold data used for the revision of ISO 7029 must satisfy the following conditions:

  • Published relatively recently (after the first edition of ISO 7029 in 1984)
  • Measured on otologically normal persons
  • Air-conduction pure-tone thresholds measured using earphones (supra-aural or circumaural type)
  • Data obtained for multiple age groups, with results reported separately for males and females
  • Results presented as numerical values or in clearly readable graphical form from which numerical data can be extracted

In the forthcoming revision of ISO 7029, audiometric data from the following publications are planned to be adopted, as they satisfy the above conditions.

Note: This list is provisional and may be modified as publications are added or removed. If you are aware of additional references that should be included or if you have relevant hearing threshold data, feel free to contact me (contact info.).
