2016 Access Cab Road Noise

Both of my 1st Gens were louder in cab than my 3rd Gen

 

Why is the picture upside down???

 

I know this is an older thread, but it was an enjoyable read.

So what brought me here? A Google search for "2017 Tacoma interior noise level." Why? Because I feel that my crew cab is also relatively loud. It's probably the low-qual stock tires (most likely...furthermore the highway I frequently travel isn't exactly a basketball court either), but sometimes when a car passes on the side, either on the road or if I'm in a parking lot, then it sounds like noise "leaks" through, almost like an cracked-open window.

 

My 2016 AC is reasonably quiet too.

 

I know this is an old post but... I noticed the cab noise on my '18 access cab on the test drive. I'm sure it wasn't in the 90+ dB range, but it was noticeable, and mildly irritating. Last week I removed my rear seats and rear cab panels to swap with another TW member who bought a Utility package but wanted the rear seats. The first thing I did was to put foam in the rear air vent holes. I used 1.25" X 1.25" X 42" long Air Conditioner Foam Weatherseal made by M-D cut up into 2+" lengths. This change alone, made a huge difference. Today, I sprayed the back panel with Boom Mat spray sound deadening. The truck is much quieter now, and I haven't even put the new trim panels on the back wall. I'm sure I'll be happy now.

 

Yep, old post, but the road noise is indeed apparent. At first, I didn't couldn't hear it too well, but after owning the truck for about a year and a half now, the difference is subtle but very apparent when the HVAC vents are on Recirc vs. outside ventilation. Drive at highway speeds and set the cruise control so speed/noise is constant. Turn on and off Recirc mode, and it can be heard. The difference of air pressure pushes open the cabin vent flaps and the noise soaks through. At 70-75MPH, the difference is probably a good -10dB on Recirc mode.
