そのI Staxtle Response Audiometryについて そのII Play AudiometryおよびStandard Audiometryについて

抄録

Startle response audiometry was performed on normal kindergartner, outpatient children in our clinic and deaf-school children with highly impai-red hearing mainly. The test utilized pure tones and thirteen social sounds.
Startle response audiometry by pure tones was compared with subjective hearing test (by using hand raising method). The reliability of startle response audiometry by using pure tones was stu-died by comparing the thresholds of first test and retest.
Pure tones were compared with social sounds as to the sound sources of startle response audiom-etry.
Pure tones were compared with social sounds as to the sound sources of startle response audiom-etry.
At the same time, play audiometry and stan-dard audiometry were performed on normal kinde-rgartner and outpatient children.
Possibility on play and standard audiometry to apply was compared. The reliability of play and standard audiometry were studied on comparison with the thresholds of both methods and variation of the thresholds between first test and retest on each methods.
The results were as follows:
(1) Startle response audiometry by pure tones was highly successfully performed on children ab-ove 3 years of age with normal hearing and impai-red hearing, on whome subjective method was im-possible to apply.
(2) The comparison of the thresholds between startle response audiometry by pure tones and su-bjective method showed the same value on 90% of normal children and 75% of children with impair-ed hearing.
(3) Comparing first test with retest of startle response audiometry by pure tones, threshold is lower in retest. The change of thresholds was within 5 phon on 70_??_90% of children tested.
(4) Startle response audiometry by using social sounds revieled higher thresholds than by using pure tones. The response of a parson change amo-ng different kinds of social sounds. The parsons with different degree and type of hearing loss have different and complicated response to the sounds.
(5) Startle response audiometry by using pure tones has a higher reliability. It can be used as a quantitative method in daily practice.
As a sound source of startle response audiom-etry, pure tones is superior to social sounds.
(6) The range of age of children, to whome play and standard audiometry can be performed are the same on children with normal and impaired hearing.
(7) Variation of thresholds between first test and retest of play and standard audiometry was the same.
Thresholds of play and standard audiometry was almost equal.
(8) Play and standard audiometry have about the same reliability. Standard audiometry is a good test which can be used as hearing test for young children as play audiometry.
