Noise Ratio

Hearing aid design to alleviate the noise problem has concentrated on improving the signal-to-noise ratio with the aid, using devices such as directional microphones, adaptive filters, and circuits that discriminate between steady-state noise and speech. The design approach discussed here is directed at improving the speech recognition of hearing-impaired listeners at a given signal-to-noise ratio, by restoring to their perception speech cues they no longer hear because of their impairment. This allows them to retain more of the redundant information in speech after masking has taken its toll, and empowers their ability to separate desired from undesired signals (what Broadbent calls "selective listening" in persons with normal hearing). Experimental results are presented.

Hearing Problems

The teachers of 2231 elementary school children were asked to identify those with known or suspected hearing problems. Following screening, the data were compared. Teachers identified 5% of the children as hearing-impaired, while screening identified only 3%. There was agreement between the two procedures on 1%. Subsequent to the teacher interviews, rescreening and tympanometry were conducted. These procedures indicated that teacher screening and tympanometry were in agreement on 2% of the total sample or 50% of the hearing-loss group. It was concluded that teachers could supplement audiometry, particularly when otoscopy and typanometry are not available.

At Home

This study attempted to maximize environmental language learning for four hearing-impaired children. The children's mothers were systematically trained to present specific language symbols to their children at home. An increase in meaningful use of these words was observed during therapy sessions. In addition, as the mothers began to generalize the language exposure strategies, an increase was observed in the children's use of words not specifically identified by the clinician as targets.
