Summary

A survey of how audiologists evaluate hearing aid telecoils, with a proposed protocol for setting the telecoil programme, from a themed issue on telephones and telecoils.

Key findings

  • Reports survey data showing no clear pattern in how audiologists evaluate hearing aids with telecoils; the great majority relied on informal patient judgments of sound quality rather than probe-microphone or speech-recognition measures.
  • Reviews formal telecoil-fitting protocols and finds that none has gained wide acceptance, perhaps because of the time and equipment they need.
  • Argues that protocols using an induction loop input do not represent telephone use, and proposes a seven-step protocol that uses a standard inductive signal source to play a known speech or noise signal while the telecoil memory is programmed.

Limits

Read from the publisher's abstract only; the full text, including the survey's size, method and date, could not be read. The article is about telephone use and dates from 2003. Its authors worked for a hearing aid maker and Pehratek Products.
