THE SEMI-ANECHOIC CHAMBER
Core configurations:
-
Semi - anechoic chamber structure combined with sound - absorbing materials, bringing the background noise down to as low as 25dBA, nearly achieving absolute silence.
-
A high - precision acoustic testing system that can capture noise data across the entire frequency range, with an error of no more than ±0.5dB.
-
A full - scenario simulation test bench that replicates real - world working conditions, ensuring the reliability of the tests.
Testing significance:
-
Quantify the operating noise to ensure that every product meets the in - vehicle noise - free standard.
-
Identify the source of noise to drive the noise - reduction optimization of products.
-
Maintain tranquility during the journey, reduce auditory fatigue, and enhance travel comfort.
