Proposal for Recommended Values of Noise Level for Indoor Public Places in Hospitals and Libraries of the Republic of China (Taiwan)

摘要

Hospitals and libraries are among the most frequently visited indoor public places by the public, of which the age distribution is comparatively wide. In order to ensure the rights of the public to enjoy a tranquil environment, we conducted indoor noise measurements for 45 hospitals and 25 libraries around our country. In the meantime, we also conducted a questionnaire survey (1,408 interviews for hospitals and 494 for libraries) and spectrum analysis in order to determine the sources, distribution and impact of the noises. Finally, the recommended values of noise level for indoor public places in hospitals and libraries were proposed (for hospitals, Ｌ_(Aeq(hr)) =60dB(A); for libraries, Ｌ_(Aeq(hr) =50dB(A)), the measurement methods were explained, and a publicity and education manual and a quietness mark were introduced in order to reduce the indoor noise level in hospitals and libraries.
