Mazda 5 Facelift - An even Quieter Place to be
Mazda 5 facelift is not only more practical and easier to use, it is also a quieter place to be, making its passenger cell even more communicative and relaxing. Engine sound, for instance, has been reduced (for all engines) by the introduction of a multi-resonator around the fresh air intake duct. It has six different types of resonators that are designed to cut noise at frequencies between 80 to 470 Hz. Road noise has also been reduced by increasing the rigidity of the rims of the alloy wheels. This reduces load wheel vibration, which is transmitted to the body and experienced as road noise by passengers, by 1 dB. And, Thinsulate® insulation sheeting has been added to the roof liner, which absorbs high-pitched road noise (at 250 Hz and above) transmitted through the body shell.
