Table (D) shows the results of the tests carried out on younger children
by means of the Audiometer and Mr. Cowan's Test Frame. The tables
and graphs, so far as they relate to children so tested, are intended to
indicate the hearing power of children of from 4 to 7 years who have
been discovered in the routine tests in the schools, and they furnish a
comparison between the hearing conditions found in infants as a group,
and older children.
The summary of the two foregoing tables is as follows:—
Of children under 7 years of age found with defective hearing, 79 per
cent. showed hearing loss in one ear only and 21 per cent. in both ears,
whereas in older children 58 per cent. have hearing loss in one ear only
and 42 per cent. in both ears. The children showing hearing loss in
both ears had exactly doubled.
The importance of remedial measures being employed at the earliest
possible moment could hardly be demonstrated more tellingly.
