NCC sound-absorbing tip Its excellent sound-absorbing performance provides an ideal acoustic environment for full/half anechoic rooms. Our laboratory with single or double wall design can meet the r&d needs of various customers with ISO 3745 and ISO 26101 accuracy level. Through a very special strong sound absorption structure, the absorption of most sound waves on each surface is realized, and the free field of acoustics is simulated, making the laboratory like an empty and silent reflection space. Sound-absorbing wedge can be selected according to customer demand and cost, including metal sound-absorbing wedge, cloth sound-absorbing wedge. Realize customized production, fully meet the requirements.

The main differences between metal and cloth chopping:

The difference of exterior material and the difference of durability.

NCC Boheng fabric wedge and metal wedge are filled with the same internal materials, including yellow standard glass wool, white formale-free glass wool, environmentally friendly fiber wool, etc.

The main difference between the two is the difference of external decoration materials, metal wedge is to use metal materials as packaging materials, the production process needs to bend, polish, and then use the paint process, the process is more complex; The cloth cutting only needs to do the cloth cover, the material is filled in the cloth cover. Therefore, the durability of metal wedge is better than cloth wedge, and the service life is longer than cloth wedge. Of course, the cost of metal wedge is also more expensive than cloth wedge, which will be about 4 times more expensive.

Cloth wedge is more widely used in major laboratories, its service life of about 30 years, to achieve the life can be purchased separately, the cost is low, and its sound-absorbing effect compared with other acoustic products, has a greater advantage.
