In the summer of 2011, German automotive magazine AUTO BILD conducted a thorough noise study. 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.
Bear in mind that a decibel rating of the interior noise level does not give you the full picture of the sound experience. 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.
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.
As 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.
Here goes the list of the Top 30 Quietest Cars according to the AUTO BILD test. The top positions were snagged by the BMW 730d, Jaguar XJ and Audi A8.
