Abstract
|
|
|
|
Frequency transposition (FT) hearing system was designed for individuals with little or no residual hearing at high frequencies. This device compresses and shifts the wide-band, high frequency acoustic energy where important features for speech perception are concentrated to the audible, lower range of frequencies. The usefulness of the FT system was investigated for 12 patients (7 childred and 5 adults) with severe-to-profound sensorineural hearing losses compared with conventional hearing aids. Results suggest that the hearing impaired can benefit from the FT system with appropriate selection criteria and auditory (re)habilitation program.
