Why use a sound level meter?
Environmental noise standards are regulations on the allowable range of noise to protect human health and the living environment. Formulating principles: It should be based on protecting people's hearing, sleep, rest, conversation and thinking, and should be advanced, scientific and realistic.
Strong noise can have adverse effects on people's physiology and psychology. In daily work and living environments, noise mainly causes hearing loss and interferes with talking, thinking, rest and sleep. Then the sound level meter is an instrument suitable for automatic measurement of environmental noise.
This instrument meets the new GB12348-2008 environmental noise emission standard for industrial enterprise boundary noise, GB22337-2008 social life noise emission standard and GB3096-2008 acoustic environment quality standard for measuring low-frequency noise real-time spectrum monitoring sound level meter instrument requirements. Has the following characteristics:
1. It has statistical analysis functions and can automatically run monitoring 24 hours a day;
2. It has octave frequency spectrum analysis function and data acquisition and measurement function;
3. The instrument has a 2.6-inch color screen display with a resolution of 240×320;
4． When the display content is rich and the backlight delay is normally on, the brightness is automatically adjusted, and others can be adjusted manually;
The Institute of Acoustics of China Academy of Testing Technology advocates to the general public that national standards provide standard support for the detection and control of environmental noise. Once people are troubled by environmental noise, or feel that their residence may exceed the prescribed decibel value, the majority of property owners should To protect your legitimate rights and interests, you can apply for testing to the relevant units with testing and arbitration qualifications. The relevant units will also refer to the testing in accordance with national standards to give everyone a safe environment.
