It should be used in all cases of children attending Schools
for the Deaf. It must be made clear that the Pure Tone Audiometer
does not rival the Gramophone Audiometer.
Children in attendance at the Clinic who were "failures" with
the Gramophone Audiometer Test are regularly re-tested as a
control. It has also been used and affords valuable information—
in nearly all the cases of Otitis Media and Nasal Conditions, with
associated deafness, to determine exactly the amount of the
"hearing loss."
All the children at the School for the Deaf were tested with
the Pure Tone Audiometer and Audiograms made of their "Hearing
Loss." The information afforded is of the greatest help to the
teacher, especially in the correct scientific setting of the Multitone
Electrical Aids suitable to each case. Periodical tests are made of
those cases at the School for the Deaf.
The Pure Tone Audiometer has also been used at the Aural
Clinic to ascertain the qualitative loss of hearing in a number of
children, which could be obtained by ordinary methods only with
approximate accuracy.
Its use will be greatly extended in association with the Gramophone
Audiometer in the proceeding inquiry into the amount,
nature, and correction of deafness amongst the whole school
population.
Both Audiometers are kept at the Clinic Centre, and any
particular cases can thus be tested during the course of the Clinic
by a member of the Clinic Staff who has special experience in this
work. This facility has been found exceedingly helpful when an
immediate hearing test is desired.
Tonsils and Adenoids.—A conservative line has been adopted
in regard to the operation for the removal of tonsils and adenoids.
It has been found that a large number of children who have had
tonsils and adenoids removed have derived little or no benefit
