AUDIOMETRY
At the end of 1970 two audiometer/vision screener operators were on the staff
of the department.
The year under review saw an added priority given to the routine testing of very
young children to the exclusion of senior school children where experience had shown
that virtually no new case of defective hearing was discovered. An increase last year
of 233 first tests and 178 re-tests on children in the very young age groups was
recorded. The number of first tests in the junior age groups declined by 192, although
there was a slight increase in the number of re-tests, but in special cases e.g. children
with speech defects and children failing to make progress in school, which have first
priority, the number of first and re-tests increased by 321 and 146 respectively.
Audiometers are kept in condition by regular calibration by the manufacturers.
Children who fail the audiometric test are referred for further investigations.
Thirty four new cases were seen and 104 re-examinations were carried out in 1970 at
the Heston Hearing Clinic to which the majority of referrals are made.
