Summary

Compared extended and restricted bandwidth in fitted hearing aids for 24 adults with high-frequency hearing loss.

Key findings

  • Twenty-four participants with mild-to-moderately-severe sloping sensorineural hearing loss used DSL v5.0 fittings with maximum available bandwidth or reduced gain above 4.5 kHz.
  • Extended bandwidth yielded an average maximum audible output frequency of 7.5 kHz for a 65 dB SPL input; the abstract reports a 4.1% consonant discrimination improvement, attributed to /s/, /z/ and /t/.
  • No significant change in loudness perception or preferred listening level was found. Forty-six percent preferred extended bandwidth and 33% had no preference.

Limits

Only the publisher abstract, author information, acknowledgments and funding statement were readable, through a Wayback Machine copy. The full paper and detailed methods were not read. Hearing-aid bandwidth evidence, not a venue-system or codec comparison.
