A new more powerful bone-anchored hearing aid: first results.
In a pilot study seven subjects were asked to use a new more powerful bone-anchored hearing aid, the BAHA cordelle, for 5 days. All seven had a moderate or severe sensorineural component in their hearing loss and had been using a BAHA superbass on a daily basis for more than 2 years. Free-field thresholds and speech recognition were measured with the BAHA superbass and with the BAHA cordelle. A questionnaire was also filled in to obtain subjective information about speech recognition with the BAHA superbass compared to the BAHA cordelle. Aided thresholds in the high frequency range with the BAHA cordelle were better than with the BAHA superbass. In six of the seven subjects there was significant improvement in the speech recognition score with the BAHA cordelle. These six subjects expressed preference for the BAHA cordelle.
