Many students at Swedish educational institutions have problems with their hearing. This is shown by a Swedish study involving more than 1,500 students, which has been carried out for the Swedish hearing organisation HRF.
40% of the students who took part in the study said that they are disturbed by noise at their institution. 42% reported often or regularly having problems hearing what the lecturer was saying and as many as 62% said that they could not hear what other students were saying during lectures.
Research has shown that a poor sound environment can reduce memory and learning ability.
Irritated and tired
Of the students who had problems with their sound environment, 78% experienced that they have trouble concentrating, 66% become irritated and over half become tired. Four out of ten have trouble remembering and 29% say that the poor sound environment gives them a headache.
The most disturbing sounds are for example voices, footsteps and the sounds of chair legs.
HRF believe that the problems with poor sound environments are especially the result of poor acoustics, bad sound insulation, poor sound engineering and improper room-layout.
1,527 students at five educational institutions in Sweden participated in the study. 80% were under 34 years of age. Around 16% said that they had reduced hearing and 14% said that they had tinnitus.
