Abstract
A new, nonelectronic hearing aid was studied in 112 patients with mild sloping sensorineural hearing loss. The device, worn all in the ear and made of clear plastic, produced a mean functional gain of 9.6 dB at 1500 Hz, 12.4 dB at 1750 Hz, and 9.1 dB at 2000 Hz, with lesser gains at adjacent frequencies between 1000 and 2500 Hz. Speech discrimination in quiet and in noise was improved. Patient acceptance of the device (in a group of 884 patients) was 76%. The device appears to be useful in the treatment of mild hearing loss.
