Whether the product is passed or not, the acoustic test ring is also an extremely important ring, so we need to set up a one-time dedicated test room for the acoustic effects of products. How much does it cost to set up such a test room?

The price of the first Silent Room is mainly determined by several factors below:
1. Silent Room needs to have a satisfactory acoustic test effect (to explain, Silent Room's internal environment and sound volume are the test products that need a satisfactory acoustic effect. In Silent Room's practical production, In the plan, the installation of a silent room to reduce environmental noise is also an important design in the acoustics effect design. Based on the practical acoustics effect, the design is based on the difference between environmental noise and the noise required inside the quiet room;

2. The inner and outer dimensions of the quiet room (determining the thickness of the sound barrier);

3. The ventilation and heat dissipation system of the quiet room;

4. Silent room type (movable, removable, fixed);
5. Other special requirements.

Due to different factors, prices have certain effects. Here is an example of a standard silent test room's approximate price. The first is the silent room's acoustic test effect requirements. Under normal circumstances, the noise level of the installation environment is generally about 60-70 minutes. , and the normal volume in the industrial area can be set to 40 minutes for the main noise level in the silent room, and the effective volume level in the silent room can be set to about 30 minutes.

The thickness of the silent room wall is designed based on the sound effect. According to the acoustic effect of the 30-minute sound interval, the thickness of the silent room wall can be up to 500mm. The size requirement for testing a silent room here is approximately 4 square meters. A small silent room can fully meet the requirements of general products. The outer dimension of the silent room is 2.5*2.5*3m, and the inner dimension is 2*2*2.5m. The size and harmony test requirements are the main factors in determining the price of a quiet room. Standard quiet rooms are generally installed in urban areas with a ventilation system and usually require low-noise air conditioning to be installed. Under normal circumstances, all silent rooms are fixed and cannot be moved. Sometimes, for convenience or to move, the silent room will be made detachable. A detachable silent room is usually 20-30 cm long. Price is %.

According to the above specifications, the price of a standard silent room is about 60,000 yen. During actual use, the standard small silent room may not meet the test requirements of customers. The specific price will be determined according to the practical parameters of the silent room. . For example, walkers, air conditioners and household appliances need a large silent room to meet the test requirements. Electric appliances such as horses, speakers and radios need lower acoustic requirements for the internal environment. The running water line silent room produces art that is comparable to that of the previous model. The special design requirements of customers in the silent room, as well as the distance from the installation site, man-made construction, etc. all affect the total price of the silent room, so the price of a large silent room can be as much as several hundred thousand yen.
