Air conditioningĪir conditioning fans create noise in themselves, plus the noise of the air exiting the vents at high speed can be considerable if the air con is on full. Wind noise will be much more if you open the windows. The less drag, generally the less turbulence and wind resistance and (usually) this results in less wind noise. Vehicle manufacturers are constantly trying to create ever more streamlined vehicles, and this is measured using the coefficient of drag. Wind noiseĪs wind hits the car turbulence is created around the wing mirrors, panel gaps, door seals, and any trim or bits that stick out. All these contribute to noise in the cabin. There’s also conducted noise through the chassis that will resonate and vibrate other parts in your car whether they are loose or not. Sometimes these parts will become a little loose and that allows them to vibrate. Your car is made of thousands of parts all screwed and glued together. Vehicles at the peak of their rev range can be very noisy – in fact, a Ferrari Enzo is well over 100dB at peak revs in first gear, which is eight times louder than an average car travelling along a road at 100kph in top gear at 70dB. If you tend to drive the car hard up through the rev range you will experience a noisier journey. If your exhaust is a performance exhaust it will offer less resistance to the sound in the silencer and will therefore be louder. If there’s a hole in your muffler then you will notice a greater amount of sound. The exhaust system channels the noise to the back of the car and uses a silencer (muffler) to dampen the noise before it exits the back. In order to propel your car forwards, fuel is exploding within the engine, and that is noisy in itself.

Later on we’ll look at what type of cars are best for this. It also isn’t something you can do much about, however, you should consider what their needs might be if you travel a lot with passengers, particularly children. This isn’t constant noise, but it can be distracting.

Whether it’s a child, your aunty or your pet dog, your vehicle occupants will make noise at some time. But what about the constant background noise that your vehicle makes, and how does this affect your concentration and health if you are in the car for long periods of time? What creates cabin noise in a vehicle? Especially when you are learning to drive, having noisy mates in the car can distract you enough to take your attention away from the road. I was hoping that I could find a way to objectively figure out if applying some of the suggested DIY fixes for the wind noise had any effect, but it looks like that won't be the case.In this article we’ll explain how noise can have a serious effect on your driving ability and your health, and what steps you can take to choose a quiet car.

Going 80 down the highway with all windows fully open would give around 74 dB, which is a much smaller increase than what I subjectively hear (yes, I know the decibel rating is logarithmic ).

Intentionally opening the windows a small crack would produce a very noticeable and loud sound of the wind, but would only increase the decibel readings by ~ 2 dB. These numbers seem to match Car and Driver's tests. When the car was accelerating I'd get spikes of 71 dB, and lows of around 66 dB. My typical test was: all windows up, ventilation off, set cruise control to 75 - 80. I have a pretty accurate meter (it was calibrated using a known 80 dB source), and would consistently get around 68 dB of noise when cruising on the highway. Unfortunately, I determined that the DB meter was fairly useless for detecting wind noise.

I did some fairly extensive testing using a DB meter before purchasing the Palisade.
