My 2015 Mazda 6 has only done about 80,000km and the cabin noise is irritating me. I do a lot of long freeway driving and I can't stand it any more. I can't make calls or listen to music unless I put it on really loud. How can I reduce the cabin noise (wind noise, road noise)? What do you recommend? I have heard there are new Active Noise Cancellation technologies around but not sure if there is an aftermarket one. I have also heard using premium tyres might help, but that’s not a permanent fix.
US-based Bose is certainly working on a system that will cancel out noise in cars. At the moment, though, it’s not available and will probably only be fitted to brand-new cars as standard equipment. At first anyway, because tech like this has a habit of tricking down to the aftermarket. However, that’s not much help to you right now.
Wearing noise-cancelling headphones is not practical (or sensible, or legal) so you need to look at an old-school solution such as the tyres you mentioned or stripping the car’s interior and fitting a noise-suppressing matting under the carpet and inside the doors. If it’s any consolation, it’s not your imagination; Mazdas for the last 20 years have been harshly criticised for their interior noise levels when the competition seems to do it better.
Ironically, active noise cancellation technology as proposed by Bose is not to tame mechanically noisy cars, but to remove wind and road noise from electric cars which are otherwise so quiet, these secondary noises become a big nuisance.
