Application of Soundproof Enclosures for Automotive Peripheral Equipment

Soundproof enclosures play a crucial role in the noise testing of automotive peripheral equipment and are a key link in ensuring the quality of vehicles and the driving experience. With the continuous improvement of consumers' requirements for vehicle comfort, the operating noise of equipment has become an important indicator for measuring vehicle quality. Soundproof enclosures effectively isolate external noise interference and absorb the sound generated by the operation of internal equipment through special acoustic materials and structural designs, providing an accurate and stable low-noise environment for testing.

In the field of motor noise testing, soundproof enclosures are particularly widely used. Take the massage assembly of a massage seat as an example. If the noise generated by the operation of the internal motor is too loud, it will seriously affect the comfort and experience of passengers. Testing the massage assembly in a soundproof enclosure can accurately capture and analyze the noise spectrum during motor operation. Engineers can optimize the motor structure, adjust the clearances of components, or improve the drive system based on this to reduce noise.

The testing of various hydraulic valves also relies on soundproof enclosures. During the operation of hydraulic valves, different degrees of noise will be generated due to the flow of hydraulic oil, the opening and closing of valve cores, etc. Soundproof enclosures create a nearly ideal acoustic environment for hydraulic valve testing, helping technicians accurately measure the working noise of hydraulic valves and determine whether they meet the design standards. Through the analysis of noise data, potential fault hazards such as wear and leakage inside the hydraulic valves can be detected in a timely manner, and improvements and optimizations can be made before the products are put into use.

In conclusion, soundproof enclosures are indispensable in the noise testing of automotive peripheral equipment due to their excellent sound insulation and noise reduction performance. From small motors to complex hydraulic valves, strict noise testing is required in soundproof enclosures. This not only improves the quality of automotive products but also brings a quiet and comfortable driving environment for consumers.

Shenzhen Saisheng Technology Co., Ltd. has a variety of soundproof enclosure products, mainly including drawer - type soundproof enclosures and pneumatic soundproof enclosures. The isolation degrees of different models of soundproof enclosures vary as follows:

ST - SG006C Drawer - type Soundproof Enclosure: It can provide a stable testing environment with a background noise as low as 25 - 30 dBA. In the frequency range of 300Hz - 20kHz, the sound isolation ability is about 40dB. The isolation degree is greater than 25dB in the range of 100Hz - 300Hz, greater than 35dB in the range of 300Hz - 500Hz, and greater than 40dB in the range of 500Hz - 20kHz.

ST - SG955 Pneumatic Soundproof Enclosure: It can provide a testing environment with a background noise as low as 30 dBA. In the frequency range of 300Hz - 20kHz, the sound isolation ability is 40 - 80dB. The isolation degree is greater than 25dB in the range of 100Hz - 300Hz, greater than 35dB in the range of 300Hz - 700Hz, and 40 - 80dB in the range of 700Hz - 20kHz.

ST - G009 Drawer - type Soundproof Enclosure: The background noise is as low as 30 dBA, which is suitable for audio testing of medium - large - sized equipment. In the frequency range of 300Hz - 20kHz, the sound isolation ability is about 40dB. When the external noise is 80dB - 90dB, the internal noise can be controlled at 40dB.

ST - SG1011 Fully Automatic Soundproof Enclosure: It can meet both manual button operation and programmed control operation and is suitable for mass production in factories. The isolation degree is greater than or equal to 20dB in the range of 80Hz - 100Hz, greater than or equal to 25dB in the range of 100Hz - 200Hz, greater than or equal to 35dB in the range of 200Hz - 400Hz, greater than or equal to 45dB in the range of 400Hz - 1500Hz, and greater than or equal to 50dB when the frequency is greater than 1500Hz.
