#Decibel rating chart for cars full

If I am to consider testing a new vehicle to purchase, the best is that the different car showrooms are all located close to each other, so that you can test them on the same roads.

#Decibel rating chart for cars full

etc etc.Ī lot of sites or magazines do give idle speed, cruising speed 60mph, 70mph and full throttle, but the thing is,…are they all done on same road surface? – cruising, higher speeds.maximum acceleration.

– coarse road surface (if possible, throw different level of coarse surface). Different people have different threshold of noise, or may tolerate different frequencies of noise better.Īpart from the complicated theories different frequency, and how it may not accurately transmit to general decibel readings, another problem with decibel ratings is that, I guess from different sites, the test is not properly done in a controlled environment.Īre all the cars been driven on exactly same road surface? To have the best real world analysis of different car’s quietness, it has to undergo complete test – Were you surprised by any of the cars in the list? Which car do you drive?Ĭould not have agreed more, you still need to test drive, decibel levels is just a guideline, but a very useful guideline.

Mercedes R 350 CDI L DPF 4Matic 7G-Tronic Noise level in decibels (dBA) at different speeds The top positions were snagged by the BMW 730d, Jaguar XJ and Audi A8. Here goes the list of the Top 30 Quietest Cars according to the AUTO BILD test. That’s why it is so important to, after having done some desk research to arrive at a shortlist of interesting cars, go for test drives in your local surroundings and listen with your own ears to decide whether you feel comfortable with the sound or not.Īs a support to your ears, do bring a decibel meter/sound meter (get one at Amazon here) so that you can measure the noise level in different parts of the car – by the left side of the head of the driver, the passenger seat and the back seat. The dBA decibel rating does not convey information about the frequency spectrums of the sound, which is something that also directly impacts how you as an individual perceive the noise in a given car. Out of the vehicles tested, they concluded which were the top 30 quietest and noisiest vehicles respectively in terms of the noise level inside the cabin of the car.īear in mind that a decibel rating of the interior noise level does not give you the full picture of the sound experience. In the summer of 2011, German automotive magazine AUTO BILD conducted a thorough noise study.
