What does 60 decibels sound like?
But any sound that is loud enough and lasts long enough can damage hearing and lead to hearing loss. A sound’s loudness is measured in decibels (dB). Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB. Following is a table of the decibel level of a number of sounds.
What makes a humming noise when going 60-70 mph?
I’ve had my Dart for 10 months and this problem just started. A loud humming noise when going 60 – 70 mph. It doesn’t matter if I am accelerating, coasting or breaking…if I am in the 60 – 70 zone the hum is happening. My RPMs seem to be fine. The noise is not the revving noise that the car makes when it accelerates.
Why does my Car Make Noise at 45 mph?
Since it only happens at 45+ MPH, and is fairly quiet to begin with, listening from outside the car is not an option and it gets drowned out by the wind when the windows are down. The sound only seems to be slightly affected by vehicle speed.
What does it mean when you hear a whining noise in your car?

Where does the humming noise come from in a car?

What kind of thumping noise does a car make?
It sounds as if I have a bold spot on a tire and is very faint. I can also feel it faintly through the steering wheel. It’s not a ticking or hard knocking noise. Also, the noise is variable depending on the speed AND the duration of noise is also speed dependent (going slow, the thump is drawn out. Going faster, the thump duration is shorter.)

Is it bad to listen to car noises?
But there are some car noises you don’t want to hear, because they can signal trouble. Every once in a while, roll down the windows and start listening for “any sound that is odd,” says Mike Peth, director of technical training at Ohio Technical College in Cleveland.
