To evaluate and possibly improve the hearing aid fittings of children atten
ding the Westphalian School for the Hearing Impaired or the Westphalian Sch
ool for the Deaf, regular pedaudiologic consulting hours were established a
t both schools. During a 2-year period, 115 children were examined once, 35
children twice,and S children three times. The examinations comprised ear
microscopy, audiometry, and a check of the hearing aids with a 0.6-cm(3) co
upler (children up to 7 years) or 2-cm(3) coupler, respectively.
The following criteria were used to assess the quality of the hearing aid s
etting: status of the external auditory canal and middle ear, acceptance of
wearing the hearing aid, status of the ear mold, technical status of the h
earing aid, and its setting. The results were related to four variables: ge
nder, type of school, age, and mean hearing loss. Overall,just 40.9% of all
children showed satisfactory hearing aid performance at the first examinat
ion and just 37.1% at the second. A significant influence of the variables
on the hearing aid performance was documented for hearing loss only. The hi
gher the hearing loss, the more likely the children were to have good heari
ng aid status. Analysis of the different parameters revealed that an incorr
ect setting was the main problem, with a rate of 20.9%; the rate of the oth
er parameters varied from 6.1% to 15.7%. Thus, no parameter was of major re
levance to the results. The results of the second examination were poorer i
n most parameters than those of the first.
These alarming results, which are probably not only of regional significanc
e, demonstrate that the hearing aid status of children attending schools fo
r the hearing impaired or for the deaf is in urgent need of improvement.
