The noise levels of electric cars compared to conventional cars?

Question

Can anyone please find the dB levels of electric cars compared to conventional cars please.

Answer 1

no

Answer 2

Our electric car is so quiet; that I feel it is a safety problem.   People do not hear us at all.  We have to watch pedestrians very carefully as well as cyclist.

The only noise is made by the tires on the road.  When I drive it; it is hard for me to tell that it is actually running.

Answer 3

Doesn't really matter.  Everybody listens to their car radio while they are driving so they can't hear any of the other cars anyway.

Answer 4

Not sure on the levels but have heard some that went past me - absolutely silent...

I think it's a safety hazard to other drivers on the road.  

Electric cars should have to play some sort of engine sound out a speaker to help identify their position to other drivers.

Answer 5

Depending on the kind of electric motor and its degree of soundproofing, the noise from the motor will be negligible.  You're far more likely to get noise from tires, wind, gears, and brakes.

If you need a simulation for a db measurement, roll down the road in a gas/diesel car and turn off the engine for a minute (not advisable on a busy or even public road).  Be careful not to crash, that makes a lot of noise.

Answer 6

Outside the car, they're pretty darn quiet, and that's been a problem for blind people.  No problem, just get one of the kits that model railroaders use to add sound to a locomotive, and you're all set!

Inside the car, you won't hear the engine obviously, but at high speed most of the noise comes from road noise and air rushing by the car.  Those won't go away.

Answer 7

They are practically silent when the engine isn't running.  Tire noise may be heard inside and outside of the vehicle, but I can see the safety issue as far as pedestrians are concerned since they can't hear the engine.  Even with the engine running they are fairly quiet, since it is so small.

Just rig up a thing like you may have done when you were a kid with the clothespin and playing card on the spokes of your bicycle spokes.  That way the pedestrians can hear you coming!
