The highest recommended sound pressure levels for leisure sounds (music) in Sweden are 100 dB LAeq and 115 dB LAFmax for adults, and 97 dB LAeq and 110 dB LAFmax 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, 42% 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.
瑞典针对成人休闲声音（音乐）推荐的最高声压级为等效连续A声级100分贝和峰值A声级115分贝，在13岁以下儿童可进入的场所，推荐值为等效连续A声级97分贝和峰值A声级110分贝。对于专为儿童设计的活动安排，声级应始终低于等效连续A声级90分贝。2005年，开展了一项全国性项目，旨在改善音乐厅、餐厅和电影院等音乐声压级较高的环境。该项目涵盖现场音乐和录制音乐。瑞典的290个市政当局中，有134个参与了该项目，其中93个进行了声音测量。共调查了471家场所，其中24%超过了瑞典休闲声音推荐的最高声压级。在节日和音乐会活动中，42%超过了推荐水平。因此，前往音乐活动/场所的人面临接触有害声级的风险相对较高。因此，该领域的持续监管至关重要。
