AUDIOMETRIC THRESHOLD MEASUREMENT IN CHILDREN WITH INTELLECTUAL DISABILITY: PREFERRED RESPONSE MODE
Journal Title: Journal of Hearing Science - Year 2018, Vol 8, Issue 2
Abstract
BACKGROUND Pure tone audiometry is primary clinical tool in assessment of auditory disorders. Hence, its accuracy is essential in success of aural rehabilitation programs. However, studies have reported that push button as response modes have significant effect on threshold in normal MATERIAL AND METHOD Air-conduction thresholds were measured for each response mode at octave intervals between 500Hz and 2000Hz in 14 ID with normal hearing sensitivity. Response mode order was randomly assigned to three different groups to measure the thresholds. RESULTS There was significant preference for using the verbal response during pure tone audiometry among ID. The results indicated that verbal response yielded threshold in significantly less time. The participants who were assigned push button or hand raise also responded with verbal response. For push button participants, this occurred before the button was pushed and for the hand raising participants, verbal response occurred before the push button. CONCLUSIONS The study finds verbal response more beneficial in measurement of auditory thresholds for persons with ID. Therefore, It is suggested that during the pure tone threshold measurement verbal response may be preferred. This may provide more accurate thresholds for rehabilitation and mangement purposes.
