The audiometric records of 158 children covering a 5 to 22 year span (average 12 years 4 months) were analyzed statistically and the degree of average initial loss and average relative shift were correlated. The average age at the last hearing test was 19 years 7 month.
It was confirmed that ears with an initial hearing level of less than 90dB (average of 3 adjacent frequencies) showed a higher rate of deterioration (average of 3 adjacent frequencies greater than 15dB) and a greater average shift than ears with an initial hearing level over 90dB. The levels of significance were 0.1% and 1%, respectively.
These results must be kept in mind in the auditory training of deaf children with hearing aids.
