How to Reduce Engine Noise?

[LaAlexander]

Reducing engine noise can be achieved by applying sound-absorbing materials under the hood. Engine noise is generated and transmitted into the cabin through the front fenders, hood, firewall, and exhaust pipe, varying with engine speed. The noise inside a vehicle primarily consists of engine noise, wind noise, and tire noise. Other methods to reduce interior noise include: 1. Installing sealing strips and door sound insulation: Wind noise is produced by the rapid flow of air against the vehicle body during motion, resulting from airflow interacting with protrusions or dead angles on the car's exterior. 2. Applying sound insulation materials to doors, door edges, wheel arches, fenders, and chassis; switching to comfort-oriented tires; and attaching soundproofing cotton to the front and rear wheel arches.
