由于城市化和工业生产、交通运输的发展,无论发达国家,还是发展中国家,噪声都是严重的环境问题。随着科学技术的进步,噪声控制有所改善,但噪声依然是导致人们感觉污染、降低环境质量的敏感问题。对干扰噪声采取的控制措施,应当仔细考虑噪声的数量和质量。声音的数量可以根据按频率校正的声音的能量来表述,相应的主观感觉是响度。然而,即使声音的能量相同,不同的 Due to urbanization, industrial production and transportation, noise is a serious environmental problem in both developed and developing countries. With the progress of science and technology, noise control has been improved, but noise is still a sensitive issue that causes people to feel pollution and reduce the quality of the environment. The control measures for interference noise should carefully consider the quantity and quality of noise. The amount of sound can be expressed in terms of the energy of the frequency-corrected sound, and the corresponding subjective feeling is loudness. However, even if the sound energy is the same, different
