Conduct comprehensive and detailed research and analysis on the current situation and trends of the automotive muffler industry
Car silencers are mainly used to reduce the noise generated by the generator of motor vehicles. The principle is that the exhaust pipe of a car is composed of two pipes of different lengths, which are separated and then intersected. Due to the difference in length between these two pipes being equal to half of the wavelength of the sound waves emitted by the car, the two rows of sound waves interfere and cancel each other out during superposition, weakening the sound intensity and reducing the transmitted sound, Thus achieving a sound reduction effect.
The 2017 China Automotive Silencer Market Status Survey and Development Prospect Prediction Analysis Report released by China Industry Research Network believes that automotive silencers are specialized equipment that hinders sound transmission and allows airflow to pass through, preventing and controlling aerodynamic noise. As of * *, in order to suppress environmental noise caused by high-pressure airflow emissions, there are already various types of mufflers in the world, most of which use impedance composite silencing principles. Due to complex structure, large weight, high-temperature oxidation sound-absorbing fillers, high-speed airflow impact sound-absorbing fillers, water vapor infiltration sound-absorbing fillers, and other reasons, frequent maintenance, poor noise reduction effect, and short service life of silencers have always been the main problems faced by automotive silencers.
The 2018 China Automotive Silencer Market Status Survey and Development Prospect Prediction Analysis Report comprehensively and meticulously analyzes the current situation and trends of the automotive muffler industry through years of monitoring and research by the automotive muffler project research team, combined with the development status and prospect trends of the Chinese automotive muffler industry, relying on authoritative national data resources and first-hand research data, Written using quantitative and qualitative scientific research methods.
