There is too much noise between elevator machines in high-rise buildings. How to eliminate or reduce noise?
The low-frequency noise generated by elevators is mainly structural sound transmission. If real estate developers do not install sound insulation and shock absorption measures, residents can install a sound insulation wall with a thickness of about 50 mm in their rooms.
Acoustic board is a kind of board with sound insulation function. There are classification of building sound insulation and structural sound insulation. Not all frequencies of sound can be blocked by sound barriers. Everything has its own natural vibration frequency, and the sound close to the vibration frequency of the object obviously reduces the sound insulation effect of the sound insulation board.
The main characteristics of sound insulation board: on the premise of ensuring sound absorption and sound insulation effect, it has the characteristics of simple manufacture and installation.
Extended data:
The noise of the elevator is unbearable, and the sound reaches the ear bone for a long time.
Low-frequency noise refers to sound with a frequency below 500 Hz. Because the noise generated by elevators is generally in the middle and low frequencies, and the human ear is not sensitive to low-frequency noise, it is easy to ignore its harm.
Dou, director of the environmental impact assessment office of China CDC, pointed out that although the impact of low-frequency noise on physiology is not as obvious as that of high-frequency noise, it can directly reach people's ear bones, making people's sympathetic nerves nervous, leading to tachycardia, elevated blood pressure and endocrine disorders.
Meng Qingshu, an otolaryngologist in xuanwu hospital, Capital Medical University, said that low-frequency noise is a kind of chronic damage to human body, which easily makes people fidgety, irritable and even lose their minds. If it is disturbed for a long time, it may also cause neurosis such as neurasthenia and insomnia, and even affect the development of the fetus in the uterus of pregnant women.
People's Network-Owners often suffer from insomnia due to elevator noise. Property response: in line with national regulations.
