Measure the sound pressure levels to which physical education teachers are exposed in gyms. In addition, evaluate the self-reported effects on physical education teachers. The sound pressure levels of ten gymnasiums were evaluated and a subjective questionnaire containing eight questions was applied to 12 teachers. The equivalent sound pressure level varied from 57 to 78 dB (A), the maximum sound pressure level ranged from 69 to 105 dB (A), and the minimum sound pressure level varied from 40 to 61 dB (A). The mean maximum
