road noise Q

[Bourbonator]

I think I remeber scrolling through some posts in which people dynamatted their doors. I think this is usually done for audio reasons, but would the dynamat, or other similar products, effectively reduce road noise? Maybe it's just me or my 4r, and I have yet to test drive other 5g 4runners, but the road noise seems... loud - compared to my sister's 5-year-old bmw. And my mother's 10-year-old mercedes.

Yeah, yeah, I searched, and after 4 pages of non-related results, I come to you all. Someone want to point me in the right direction?

On a side note, traveling at 50mph with all windows up is almost as noisy as driving at 50mph with my driver side window down and rear window cracked.

And I continued my search and read that using dynamat doesn't deaden sound, but resonance on the panel on which it's installed. To reduce sound, you need to use foam as well. (correct?) I would be greatly appreciative if anyone had experience with dynamatting and adding foam to reduce road noise, and could chime in with their experiences and results.

Mass load vinyl?

Not sure if this will help, but mine does not have a lot of road noise nor do the doors sound "tinny" when closing etc. etc. Looking at the sticker, amongst other things, the SE Toyota Distributer added a "sound seal" package.

(I did not order this, it came with the vehicle on the lot). In any case, whatever they did, it worked. My 4runner is very quite and very solid sounding. You might want to call SE and see if they will tell you what they do/did to quiet the 4runner. Here is their contact info- Southeast Region (NC, SC, AL, GA, FL) 954-429-2000.

The package in which the sound seal is found is coded as XY7, "Toyo Guard Plus protection group"and has about 8 other things included with the sound seal like undercoating, first oil change for free, exterior paint sealant and interior protection etc.

Hope this helps, be safe.

Apples to Oranges here, sorry. "You get what you pay for" type of situation. Can't really compare 'luxury' cars/suvs to the 4R.

...doors sound "tinny" when closing...

Have you seen the new (forget the make/model) commercial where they close the doors and there is a solid 'thunk' and things fall from the trees? If it was an SUV commercial I would think it would be directed at the 4R . The 'tinny' sound is the worst when you open the window and close the doors, yikes. I ignore it though, it does not bother me enough to worry about.

I did a complete cover in Dynamat; it added about 180lbs, but, the difference was night and day; it's extremely quiet in the cabin. Dynamat doesn't absorb sound, it absorbs vibration (sound is vibration); whatever, it works. I did doors, roof, pillars, rear hatch, etc., anything exposed to outside noise, excluding glass, of course. During rain, you only hear what’s hitting the glass. I installed a hood pad too, but, I do get a little engine noise, but, it’s negligible. Oh, by the way, when you open or close the doors... think Lexus. Actually, the car is as quiet or quieter than my GS was. Fantastic stuff. There are other products out there, including foam; I researched all of them and opted for the Dynamat for ease of install and consumer and industry feedback. I've had it in for about 1 year and I'm still amazed at the difference. My E500 wagon isn't this quiet. My 5th Gen 4RT is a whole new ride... and the music from the JBL sound system is improved, too.

I know what my next mod will be.

Yea, seen it. Pretty funny. Because I got mine "sound deadened" from the get go, I never experienced the "tinny" sound. I was referring to others on other threads who have. Like I said, whatever they did, it worked!

I'm not suggesting you go the cheap route, but I used rattletrap on the doors and the hatch and it made a huge difference. Even a modest install seemed to make a night and day difference. The complaint about rattletrap is it smells like roofing material which is true, but the smell fades to nothing in just a few days.

The doors are insulated from outside noise and when the doors shut they have a much more solid feel to them.

Silent Running - high performance sound and vibration dampening coating for marine vessels

Demonstration is pretty impressive. Thinking about ordering some.

This stuff would be amazing if it works as well as Dynamat. There could be some serious weight savings.

considering new tires? even as EV cars pass by, the tires make a ton of road noise

Whether you are a noisy person or a person who wants to enjoy a quiet time, we recommend road noise barriers for road noise cancellation. Also known as noise barrier tarps, these barriers absorb noise and can also prevent them from passing from road to residential areas. With these noise barrier, road noise cancellation or reducing road noise in garden becomes easy. You cannot see sound, but sound works like light. If the obstruction will block the line of sight between you and the noise source, it will also block the sound.

I guess that if this has not happened yet on this 9 year old thread it is probably not going to happen.

I think in the nine years that have passed since the OP, a solution has probably been found :ybrick:

 

[Ripper238]

The 4R is not that noisy. Do you have a roof rack, cross bars or any roof top storage?

Edit:
Hahahah

Gets me every time.

We just sold our 15 GX460 and bought a 21 TRD Off Road Premium. Both my wife and I feel the interior noise is the same, if not better.

Great Scotts Marty!
