Deadening:

Floor 100% (completed)...
Trunk 80%
Doors 85% (finish right front door)
Fire Wall 75%
Roof 0%
Front fenders 0%
Engine Hood 0%

I have to say that by doing the floor, doors and most of the firewall the noise level is surprisingly lower that what I expected, It used to be that my 04 Corolla was much quieter that my 08 Yaris, now it's vice-versa! and I could express this feeling in some ways...

-Yaris feels much solid than the corolla now, after driving my corolla for several days or hours and moving back to my Yaris I would experience a feeling of cheap, hallow plastic/metal, noisy and sometimes toyish felling. Not any more!

-You feel the bumps but barely hear them (this is a nice feeling)

-The ride quality between when it was brand new has improved to the point that it doesn't feel like the same car I drove from the dealer to home


Some things that I don't like...

-The height of the floor raised significantly that bothers the operation of the clutch, I took care of this by cutting some of some CCF. But still bothers me a little bit, so the seat mod would have to happen pretty soon. If you don't know what I'm talking about is in this thread about lifting the front of the seat a little bit:

- .....LINK

-A lot of the Panels don't fit back properly in their place (this is because the extra layers of deadening material underneath) some modification has to be done, trimming, cutting, adjusting, etc

-Some panels will break when pulling apart, I broke 2 allready 1 panel that goes in the trunk and 1 panel at the bottom sill of the front left door.

-It's time consuming! and you need good tools to accomplish several tasks like... taking the seats off, seat belts, pulling panels, etc.

-Add more weight to my car, it really doesn't bothers me, and I'm still getting 42.34 MPG; it's more stable than before specially on the highway and cross winds.


But after all (even I'm not finish) the results are very satisfying. I wish I could increase the thickness of the glass of all windows and windshield, increase the thickness of the sheet metal of the car and to be able to treat the Firewall from the engine compartment.

I have a few recommendations...

-If you are only going to treat a section start with the floor and wheel wells; then the doors and I started with the rear doors gaining experience for the front doors and harder to treat.

-Consider using CLD Tiles to control resonances

-Consider CCF to absorb resonances on top of the metal and CLD tiles

-Use CCF as a cushion between panels and prevent rattling

-I highly recommend the use of MLV as a sound barrier this will really help reducing outside noise into your car. Even though it's very hard to work with and you have to be creative.

*Would I do it again?

................................YES!..



Now I'm going to focus more in my stereo upgrade I will finish deadening the other areas and I will post in this thread as well....

Thank you every body for your help, comments and recommendations.

I'll keep making my car less noisier, so I can make it louder!

Thanks

[Alien Mantis]

Yes.

Don't get me wrong... the Yaris NEEDS "deadening".

OK guys she WON!



now there is another reason to go quiet...

Congratulations man! There's nothing in the world like love at first sight.

[Herbicidal]

Congratulations!!! I guess if you have to 'lose', what a way to go.

[Palmer812]

Congrats!!! We now know the real reason you spent all that time deadening the Yaris. When the baby won't stop crying you have somewhere to go and hide.

[gates_2]

Congrats! That must be really exciting!


Quick question..anyone have problems with getting the C pillar off? I'm in the process of gutting my HB to put in deadening, and there seems to be like a metal cliplike thing holding the C pillar in place quite firmly (its different from the other white plastic clips)- Advise?

My C pillar was very easy to pull off.

Thanks guys,

Looks like tomorrow night we'll go back to this project.

Herb, I got your meter, will test soon.

Take any readings yet from your newborn? I KNOW she is not always that quiet and photogenic!!!

I haven't had a chance to do that! she is not very loud! she sleeps eats and you know.

I replaced the 9v battery and drove to work, the meter it's very tricky and I'm slowly finding how it works, even a small change on pavement the numbers increase, even if I talk or sneeze, small bumps on the road, a truck passing by also make the numbers go up or just changing the position of the meter or touching it as well.

Also the position and orientation makes a difference, pointing at the windshield the #s increase a little bit. It's not fair to record MAX readings for reference, so I'm posting actual readings as I drive on the highway...


at 75mph reads... 74db to 78db a small bump or changes in surface bumps and reads... 80db for 1/2 a second

at 65mph reads... 61db to 68db
ps... GPS speed in MPH

All this with the center of the car open (no center console) and no front passenger's seat either and the front left wheel well untreated.

I would like to try this in my Dad's Mercedes...


A couple of nights ago I put some Mat and Ensolite to the center console, I didn't spend a lot of time here, I just wanted to reinforce the plastic panels a little bit, and prevent rattling, I'm also concern on getting back in place this piece, so I didn't put any Mat or Ensolite on the edges... here are the pictures:

You're welcome for the use of the meter.

I'll have to try the highway readings like you did just for comparison and yes, I realize this is all just for fun. However, I'm not taking out my passenger seat or the center console!

[derickveliz2]

Ok, my intention was to record video clips at highway speeds, please don't do this at home LOL

Sorry for the crappy video quality

This video is driving at 70 mph (cruise control) no center console, no front passenger's seat either and the front left wheel well untreated. PS... thanks to herb for letting me use his db meter.

This video is at 80 MPH... CRANK up the volume of your speakers and hear the noise coming from the stick as I move the camera from it.
