CIC Buyer's Guide |
| |
Completely-in-the-canal (CIC) hearing instruments are the smallest and least visible of custom ITEs. First introduced in 1993, CIC instruments have since grown in popularity to comprise about 14% of all hearing instruments dispensed (HIA statistics, 2nd Quarter, 2000). Today's CICs range from analog linear to digital programmable, and have a great number of benefits beyond their cosmetic value including enhanced telephone use, improved sound localization, wind noise reduction and high frequency gain. This section of The Hearing Review is intended to provide information about the latest CIC hearing instruments. Descriptions of the products listed below were provided by the manufacturers upon request of The Hearing Review. |
