Why is the car so noisy?

The reasons for loud car noise are as follows: 1. The engine mount rubber is aged or loose. In fact, the rubber blocks between the engine and the frame, if these engine mount rubbers become aged or loose, the engine will vibrate, and the faster the speed, the louder the vibration sound will be. It is necessary to tighten or replace the engine mount rubber. 2. If the oil viscosity does not match the engine, it is easy to produce carbon deposits, causing the engine noise to increase. 3. Engine misfire, mainly refers to one or more cylinders of the engine not working properly, usually manifested as obvious intermittency in the exhaust gas flow from the car, and severe shaking of the exhaust pipe, and the engine's "puttering" or "thumping, thumping" sound can be clearly heard.
I think excessive car noise is a very common issue, and I've encountered it several times over the years of driving. There are several main causes: Engine compartment problems are the most prominent. A loose belt will produce a squeaking sound, an exhaust leak causes a puffing noise, and if the engine oil hasn't been changed for too long, it can also make the engine noisier. Tire issues are also frequent – both overinflation and underinflation can easily cause a humming noise, and worn tread patterns will increase tire noise. For the car body, aged door seal strips can cause wind whistling noises, and loose underbody panels will rattle on rough roads. Additionally, maintenance habits have an impact too. For example, a clogged air filter forces the engine to work harder and louder, while pebbles stuck in tire treads create a tapping sound when rolling. My suggestion is to first identify the pattern when noticing noise: if it occurs at idle, check the engine; if it happens at high speed, investigate tire or wind noise – this approach can save a lot of unnecessary repair costs.
