What are the reasons for the loud noise inside the Lavida?

Automobile noise mainly comes from the engine and tires. Solutions: Excessive engine noise can be reduced by changing the engine oil, using an intake duct with sound insulation, wrapping the exhaust and cylinder head with soundproofing felt, and adding sound insulation to the engine cover. Tire noise is primarily caused by the tire material, tire pressure, tread design, and abnormal tread wear, which can be addressed by directly replacing the tires. Adjusting tire pressure: If the car tire pressure is too high or too low, it can also produce different noises. Therefore, adjusting to the appropriate tire pressure can help reduce noise appropriately. If the interior noise is very loud, you can also switch the air conditioning to internal circulation to reduce the air flow noise caused by external circulation. The main source of interior noise still comes from the engine compartment. If the engine noise is excessive, an engine inspection is necessary. Noise reduction can be achieved by installing soundproofing cotton under the hood, applying soundproofing materials to the firewall, and also attaching soundproofing materials to the door panels, which can help reduce noise from the outside.
I've found that the noise inside the Lavida is quite loud, mainly due to several reasons. Having driven this car for several years, I've experienced similar issues. The most common source of noise is tire-related problems, such as excessive tire wear or insufficient tire pressure, which can make road vibration sounds particularly loud, especially on rough surfaces. Wind noise is another major contributor; when the window seals age, the sound of wind rushing into the cabin at high speeds can be quite annoying. If the sound insulation panels in the engine compartment are damaged or aged, the roar of the engine can easily penetrate, especially noticeable during acceleration. Worn suspension components, like shock absorbers, can lead to chassis noises, producing a thumping sound on bumpy roads. Internal factors also play a role, such as loose interior panels or unsecured items in the trunk, which can add extra noise. I recommend starting with simple checks, like inspecting tire wear and pressure. If that doesn't help, visiting a professional shop to use instruments to pinpoint the exact noise source would be advisable. Regular maintenance, including replacing old parts, can significantly improve the quietness of the car.
