How to eliminate noise in Tiguan?

[DeHailey]

Methods to eliminate noise in Tiguan are as follows: 1. To reduce engine noise, attach sound-absorbing materials under the hood. 2. To reduce wind noise, install sealing strips or perform door sound insulation. 3. To reduce tire noise, replace with comfort-oriented tires. Details are as follows: 1. Engine noise is generated and transmitted into the cabin through the front fenders, hood, firewall, and exhaust pipe as the engine speed varies. Therefore, vibration damping and sealing these areas can effectively control and reduce engine compartment noise. 2. Wind noise occurs during vehicle movement due to friction between rapidly flowing air and the car body. It enters the cabin through door gaps, so only by enhancing the vehicle's tightness and sound insulation can it be reduced. 3. Tire noise generally consists of three components: air noise from airflow in tire tread gaps and surrounding air disturbance, vibration noise from the tire body and tread patterns (particularly noticeable as road noise and uneven surface noise), and amplified resonance noise formed by friction/impact between tread and ground (especially on bumpy roads) combined with vibrations from components like fenders and mudguards.
