  1. OtoID: New extended frequency, portable audiometer for ototoxicitymonitoring Marilyn F. Dille, PhD; Peter G. Jacobs, PhD; Samuel Y. Gordon, BSEE; Wendy J. Helt, MA; Garnett P. McMillan, PhD

  2. Aim • Report on validation and verification of OtoID portable audiometer that allows hearing testing on hospital treatment unit and automated patient self-testing. • Relevance • Portability of equipment is increasingly important component in practice of audiology.

  3. Method • 40 subjects: • Young and old. • With and without hearing impairment. • Conditions: • Manual hearing test by audiologist vs self-test with automated testing. • Sound booth vs hospital treatment unit. • Data analyzed for: • Testing bias, repeatability, and American Speech-Language-Hearing Association-significant ototoxicity false-positive rate.

  4. Results • OtoID automated and manual testing modes provided equivalent and repeatable results in subjects who varied in age and hearing status when tested in both locations. • Further, there was little potential for false positive (for ototoxicity) findings.

  5. Conclusion • OtoID device will: • Enable widespread ototoxicity monitoring, • Allow clinicians to minimize or prevent progression of hearing loss.
