With the development of urbanization and industrialization, people are increasingly exposed to noise in their daily lives. Noise is a harmful environmental pollution, how many decibels of noise are harmful to human health? This article will explore this issue. Firstly, how is noise measured? We usually use decibels as the unit of measurement for noise. Decibel (dB) is a relative unit used to measure the intensity and volume of sound. The greater the noise, the higher the decibel level, and the maximum range of human hearing is 0dB to 140dB. 0-40 decibels is a very quiet environment, suitable for sleep; Normal living and working environment is around 40-70 decibels; A noise level above 70 decibels is very loud, and long-term living above 85 decibels can cause harm to human health. Generally speaking, for every 10 decibels increase, the level of noise pressure increases tenfold, and the intensity of sound also increases tenfold.
Read MoreWhen accepting the anechoic chamber, selecting measuring points to test the acoustic effect is a very important step. Here are some suggestions to help you select measuring points and perform acoustic testing: Determine the number of measuring points: According to the size and design requirements of the anechoic chamber, determine the number of measuring points that need to be tested. Usually, several measuring points should be evenly distributed inside the anechoic chamber to ensure that the acoustic performance of the anechoic chamber can be fully evaluated.
