Where is the noise reduction position of Honda CRV?

[DiTravis]

Honda CRV's noise reduction position is located above the rear roof. Automotive active noise cancellation refers to a noise reduction technology that generates reverse sound waves equal to external noise through the noise reduction system to neutralize the noise, thereby achieving vehicle noise reduction. Below is some relevant information about automotive active noise cancellation: Working Principle: By emitting sound waves opposite in phase and equal in amplitude to the noise source through noise-canceling speakers, the two sound waves superimpose to achieve the purpose of noise cancellation. Noise Reduction Range: Some of the vehicle's noise comes from the engine and transmission system. The active noise cancellation system cannot achieve a transformative effect but can only further improve noise reduction on the basis of physical noise reduction, with limited noise reduction range.
