This study introduces a new PC-based system for measuring bone-conduction (BC) hearing aids directly on the patient. The system assesses hearing aid vibrations against individual hearing thresholds, offering a more precise adjustment method.

Area of Science:

  • Audiology
  • Biomedical Engineering
  • Signal Processing

Background:

  • Traditional bone-conduction (BC) hearing aid fitting relies on skull simulators and subjective psychoacoustic free-field audiometry.
  • Objective in situ measurements of BC hearing aid performance are lacking.

Purpose of the Study:

  • To present a novel PC-based system for in situ measurement of BC hearing aids.
  • To correlate hearing aid induced skull vibrations with individual BC hearing thresholds.

Main Methods:

  • Development of a PC-based system for real-time measurement of skull vibrations.
  • Integration of BC hearing threshold data at specific frequencies.
  • In situ testing of BC hearing aids on individuals.

Main Results:

Related Experiment Videos

  • The system successfully measures hearing aid induced skull vibrations in relation to individual BC hearing thresholds.
  • Preliminary measurements indicate low vibration levels, but demonstrate sufficient system sensitivity for relevant data acquisition.

Conclusions:

  • The novel PC-based system offers a promising approach for objective, in situ assessment of BC hearing aids.
  • This technology could lead to more accurate and personalized BC hearing aid adjustments.
