Automated Audiometry
Scoping Review

Here you find an overview of all automated audiometry approaches included in the scoping review published in JMIR. When multiple reports described the same underlying approach, these reports were pooled in one approach-cluster.

Living document

We would like to further expand this overview as a living document. If you find an approach not yet included please reach out to us.

Below you find an overview of all automated audiometry approaches included in the scoping review published in JMIR. When multiple reports described the same underlying approach, these reports were pooled in one approach-cluster. The name of the approach, citations to the initial report and/or common authorships were used to cluster the reports.

Inclusion criteria were:

  • Validated approaches of pure-tone threshold audiometry
  • published in the period from juli 2012 to juli 2021 in a peer-reviewed journal

We would like to further expand this overview as a living document. If you find an approach not yet included please fill out this form so that we can add it. Also if you find new report that could be added to an existing approach please let us know. You can send your suggestions to resources@computationalaudiology.com

RMSD fell below 5 dB after a median of 67 trials using an automated Hughson-Westlake algorithm for unilateral air audiogram in normal hearing and hearing impaired. The MLAG algorithm 49 trials for the same accuracy(Barbour et al. 2019).

Mean testing time 2.1-4.8 minutes for bilateral air audiogram in normal hearing. RMSD fell below 5 dB after 19-44 trials.

Mean testing time 5-7 minutes, for bilateral air audiogram in hearing impaired. RMSD fell below 5 dB after 50-63 trials(Heisey et al. 2020).
