Data obtained from a questionnaire survey of 152 deaf adults living in Colorado are reported for the purpose of acquainting speech and hearing personnel with a hearing loss group who use manual communication. The respondents were questioned concerning their medical and audiological history, communication abilities and preferences, as well as their educational, vocational, and social backgrounds and environments. The data suggest that this deaf population seldom utilizes otologic, audiologic, or speech pathology services, although indications were noted of interest in such activities. It is suggested that an increase in understanding by speech and hearing clinicians of this profoundly deaf population may result in mutual benefits to both groups.
