Car noise at 65 decibels is considered high. Below are common classifications of car noise: 1. Engine noise: The vehicle's engine is a source of noise, which varies with different engine speeds. 2. Road noise: Road noise is generated when the vehicle is driving at high speed, caused by wind cutting in and the vibration of the chassis, as well as sand and gravel impacting the vehicle's underbody. These are the main sources of road noise. 3. Tire noise: Tire noise is produced by the friction between the tires and the road surface during high-speed driving. The level of tire noise depends on road and vehicle conditions; the worse the road condition, the greater the tire noise. Additionally, there is a significant difference in tire noise between asphalt and concrete road surfaces.

I've been driving for a while and think 65 decibels of car noise isn't very high, but it might feel uncomfortable in daily life. During normal driving, the interior noise typically ranges from 50 to 70 decibels. For example, cruising on city roads at 65 decibels is quite common, sounding about as loud as a normal conversation. If the car is older or the tires are heavily worn, wind or engine noise can increase, making it easier to feel fatigued. On long drives with 65 decibels of noise, I pay attention to checking window seals or upgrading soundproofing materials to improve comfort. Legally, many places set a standard of up to 65 decibels during the day as acceptable, so this isn't exceeding limits—no need to worry too much. However, if frequently exposed to such noise, it's still advisable to do some simple maintenance to reduce it.

From my experience, 65 decibels of car noise is at a moderate level—neither high nor low. Common vehicles reach this value during acceleration or high-speed driving, similar to the volume of a vacuum cleaner working. Professionally speaking, this noise level won't cause immediate hearing damage, but prolonged exposure to 60-70 decibel environments may lead to fatigue and stress, affecting driving concentration. I believe checking tire conditions and chassis components is crucial, as worn parts can amplify noise. Urban noise standards typically limit around 65 decibels, which most vehicles comply with. Simply put, 65 decibels in a car is quite common, and maintaining good habits like closing windows can easily control it.

When considering health impacts, 65 decibels of car noise isn't highly hazardous, but may cause mild discomfort. Typically, such noise comes from wind or engine sounds, equivalent to normal conversation volume, which could potentially lead to fatigue or even headaches while driving. Short-term exposure is fine, but prolonged exposure may increase stress risks. I recommend replacing worn tires promptly to reduce noise sources, while regular vehicle maintenance helps with noise reduction. At 65 decibels, it's not extremely loud - just avoid excessively noisy cabin environments.
