title: Field trials of a tactile acoustic monitor for the profoundly deaf.
abstract: Profoundly deaf subjects were given information about sound level in their environment by means of a body-worn unit coupled to a small vibrator worn on the finger. Results of trials on 19 adults are discussed. The Tactile Acoustic Monitor was found to be useful for identifying domestic sounds by means of their distinctive timing patterns. No significant overall improvement in subject's control of voice level was observed, although some subjects found that having a voice level monitor gave them greater confidence to join conversations. Various design improvements were suggested by the trials. Modifications which have been incorporated into an improved unit are described.
