What is the level of 60 decibels of in-car noise?
2 Answers
In-car noise of 60 decibels is within the acceptable normal range. Here is additional information: 1. In-car noise requirements: According to the "Technical Conditions for Safe Operation of Motor Vehicles" issued and implemented by the former National Bureau of Technical Supervision on January 1, 1998, the in-cabin noise level for buses should not exceed 82 decibels; the noise level near the driver's ear should not exceed 90 decibels. If the in-car noise is below 60 decibels, it is considered within an acceptable range, with 40-60 decibels being the normal range for conversation. 2. Sources of in-car noise: 1. The vehicle engine is one source of noise, which can be generated and transmitted through the front fenders, hood, firewall, and exhaust pipe. 2. Road noise is produced when the vehicle is driven at high speeds, caused by wind cutting in and vibrations from the chassis, as well as gravel hitting the chassis.
Hey, after driving for so many years, I often experience in-cabin noise on highways or urban roads. 60 decibels sounds like the level of normal conversation, not too harsh. While driving, this is equivalent to the sound of the engine running smoothly with windows closed, comfortable enough to clearly hear music or podcasts. I've tested it myself with a car app, 60 decibels is usually achieved at around 50 km/h in the city; if the noise exceeds this, say reaching 70 decibels, it might mean the windows aren't properly closed or there's a tire leak, so it's worth checking. Regular maintenance like oil changes and cleaning air conditioning filters can effectively keep noise within safe limits. A 60-decibel driving experience is quite pleasant, doesn't affect concentration, and is suitable for long trips.
