1. Soundproofing room (quiet room):
-A soundproof room is a specially designed room used to reduce the impact of external noise on the internal environment. It usually adopts a multi-layer polymer composite sound insulation board structure, which has efficient sound absorption and insulation effects.
-Widely applicable in various fields, including testing of electronic products such as speakers, microphones, small motors, household appliances, automobiles, mobile phones, Bluetooth earphones, small fans, etc.

2. Silencing chamber (anechoic chamber):
-An anechoic chamber is a special type of acoustic room designed to minimize sound reflection and echo to the greatest extent possible. This type of room is typically used for high-precision acoustic testing and measurement.
-The acoustic effect of an anechoic chamber can usually reach around 20-2dB (A).

3. Microplate soundproof room:
-The microporous board soundproof room adopts microporous board as the main material, which has good sound absorption effect. This type of room is usually used in situations where high sound insulation is required.

4. Silent assembly line room:
-The assembly line soundproof room is designed specifically for production lines, providing excellent sound insulation without affecting the production process. Its sound insulation effect is usually 75dB for the outside and 40dB for the inside.

5. Signal shielding room:
-The signal shielding room not only has sound insulation effect, but also shields electromagnetic signals to prevent external electromagnetic interference from affecting the normal operation of internal equipment.

6. Radio anechoic chamber:
-An anechoic chamber is a special shielded room used for testing and measuring electromagnetic compatibility (EMC). It is covered with absorbing materials inside, which can simulate the electromagnetic environment of free space.

7. Shielding tank:
-A shielded canister is a small shielded room typically used to test the electromagnetic compatibility of small electronic devices.

8. Test the network room:
-A test room is a specially designed room used to test the performance and stability of network equipment.

These types of noise testing rooms have their own characteristics and application scenarios, and suitable types can be selected according to specific testing needs.
