Introduction. Teachers as well as other people of similar
age can be affected by acquired hearing disorders, inevitably
deteriorating quality of verbal communication.
Objectives. The aims of this work included audiometric
assessment of hearing in teachers with focus on the problem
of hearing among these professionals, as well as highlighting
the resulting difficulties in the process of oral communication
between teachers and their students.
Material and methods. Results of screening tests of primary
school teachers of rural schools from different parts of Poland
have been assssed. The material was acquired during the program
implemented by the Institute of Physiology and Pathology of
Hearing in cooperation with Agrarian Social Insurance Fund
in 2008 and 2011. Nine hundred twenty two teachers were
included in the examinations; 1680 women and 242 men. Pure
tone tests were performed at 500 Hz to 8000 Hz frequency
band using the Senses Examination Platform. Hearing threshold
elevated to 25 dBHL or more for at least one frequency within
the 500-8000 Hz frequency range was regarded as abnormal
result of pure tone audiometry test.
Results. The analysis of audiograms shows that ca. 35.3% of the
examined teachers had hearing losses of different degree. The
prevalence of hearing defects in teachers grows with age. Flat
or ramp-shaped audiograms accounted for the majority, nearly
90%, of all studied hearing loss cases.
Conclusions. In spite that the averaged audiograms of the
teachers were within normal values for the respective age
groups, considerable hearing impairments were recorded
already in teaches younger than 50.
