A NATIONAL PROJECT TO EVALUATE AND REDUCE HIGH SOUND PRESSURE LEVELS FROM MUSIC

摘要

The highest recommended sound pressure levels for leisure sounds (music) in Sweden are 100 dB LAN and 115 dB Lmmax for adults, and 97 dB LAeq and 110 dB Lmmax where children under the age of 13 have access. For arrangements intended for children, levels should be consistently less than 90 dB LAeq. In 2005, a national project was carried out with the aim of improving environments with high sound pressure levels from music, such as concert halls, restaurants, and cinemas. The project covered both live and recorded music. Of Sweden's 290 municipalities, 134 took part in the project, and 93 of these carried out sound measurements. Four hundred and seventy one establishments were investigated, 24% of which exceeded the highest recommended sound pressure levels for leisure sounds in Sweden. Of festival and concert events, 420/0 exceeded the recommended levels. Those who visit music events/establishments thus run a relatively high risk of exposure to harmful sound levels. Continued supervision in this field is therefore crucial.
