Motor Trend March 2016 issue has an article "Three Rows & A Baby Turbo" reviewing the new Mazda CX-9. There is this:
"The engine soundtrack isn't the only thing missing from the CX-9's cabin. There isn't much road or wind noise, either. Weight-saving measures in the structure (and the lighter engine) helped pull some 250 pounds out versus the last CX-9, and that gave Mazda's engineers some latitude to put back in extra sound-deadening materials. By comparison, the smaller CX-5 has just 9 pounds of sound-deadening material in the floor to the CX-9's 53 pounds. The CX-9 also has acoustic glass in the windshield and, for the first time in a Mazda, in the front side windows. The acoustic treatment reduces interior noise levels by the claimed 12 percent at the highway speeds compared with the outgoing CX-9."
Based on its press release, I thought Mazda had put "particular effort" to "enhance sound insulation performance throughout the body" on 2016 CX-5? The result was only 9 pounds of sound-deadening material in the floor on the CX-5? No wonder so many people are complaining the noise level in the cabin!
Hopefully Mazda will consider more sound-deadening materials and acoustic glass at least to the next generation CX-5 to reduce the noise level in the cabin.
