A soundproof box is a metal tool like a box used to isolate external noise interference. When testing a product in a certain sound environment, what is the noise level of the test product? If the test product is required to be tested in an environment with an external noise level of 70 decibels and a temperature of 30 decibels inside the box.
Main function and scope of application: Provide a sound insulation testing environment for product noise inspection, also known as audio shielding box. The sound absorption tip of the sound insulation box is a special sound absorption structure dedicated to anechoic and semi anechoic rooms, with a minimum cutoff frequency of 40Hz, which can achieve sound absorption characteristics of over 99%. Suitable for the testing of electroacoustic parameters of electroacoustic products, as well as the measurement and scientific experiments of various mechanical, electromechanical, light industrial and household appliances and other products. In engineering, sound absorption structures are often made into fixed products. When selecting various types of sound absorbers, it is not only necessary to understand their performance, but also to install them correctly in order to achieve high sound absorption, low cost, and economic and practical effects. The area ratio and peak height are the main factors affecting the sound absorption efficiency of sound absorbers
Sound barrier structure
1. The outer surface steel plate of the soundproof box wall has undergone degreasing, phosphating, and spray molding treatment.
2. The walls of the sound insulation box are all made of 2mm thick national standard cold rolled steel plates.
3. The interlayer of the sound insulation box wall is made of multi specification density fireproof and environmentally friendly sound-absorbing cotton, medium density board, and damping board.
4. The wall of the sound insulation box is made of 8 cm peak absorbing cotton.
5. The interlayer of the soundproof box wall is made of soundproof panels.
