Improving behavior observation audiometry testing and scoring procedures.

The need exists for improving behavioral testing of low-functioning children, particularly profoundly involved multiply handicapped children. In this study, behavior observation audiometry (BOA) was modified for systematic evaluation of childrens' responses to sound without observer bias. The data were analyzed statistically and a minimum response level was computed. This BOA technique was used to test the hearing of 82 profoundly involved handicapped children. Results suggested that BOA can be helpful in evaluating the hearing of low-functioning children.
