Telephone performance of persons with hearing handicap in relation to speech reception threshold.
This investigation shows that there are four relevant methods of telephoning in Denmark for hearing-impaired persons: 1) Standard telephone without extra equipment for persons with a Speech Reception Threshold (SRT) up to about 40 dB in the better ear. 2) Standard telephone with receiving amplifier for persons with a SRT up to about 60 dB in the better ear. 3) Standard telephone plus individual hearing aid primarily in "T" position. Can be used by hearing-impaired persons with a SRT up to 70-75 dB in the better ear. 4) Standard telephone with receiving amplifier plus individual hearing aid primarily in "T" position. This is an effective and cheap solution for hearing losses above 70-75 dB in the better ear.
