That makes sense because this is working as a binaural recording. Your head just got to be the size of the car. IMHO it shouldn't matter that it's a car because we're still working with left and right...like headphones.

I'm making this a standard for my demo.

Base coat is on:



Three coats of Toyota OE1 base coat. The kick has three coats of automotive primer so far.

[derickveliz2]

Looking good! any more shots of the kicks? I think I'm just going to use the OEM kicks and cut a hole, then cover with grill cloth, for the Mid-Bass (LOWS) I'm still thinking about it.

PAT M, sent me a few tracks, some similar to the virtual hair cut, the effect is good, but not as good compare to headphones, also sent me some bachata songs! that rock the Latin way!

Thanks PAT M.

[sqcomp]

I actually do have the kicks installed at this point...BUT...

I've got another plan for the door panels that I'm exploring right now. I think I'll hold off on pictures of the area until I'm done with the panels.

I worked on more deadening, and guess what??

This is GREAT! very simple and effective:

There is something very easy to do that kills most of the engine noise and kills completely the noise from the little motor and mechanism of the wipers!

Materials used less than 3 square feet of MLV, 1 sq ft of thick MAT and left overs of 1/4 ccFoam, Time about 2 hours (for me at midnight)

Will try to explain later with more details.
Driving at about 80mph RPMs are around 3.5K and it's very quiet! 4k RPMs at 90mph and still very quiet! (O:

.... you've left us hanging! Aduh! Can't wait to hear where the sweet spots are!

[derickveliz2]

Sorry, over the weekend I try to spend more time with my family, and try to avoid computer contact, jeje.

Well...
You know me I'm chasing noise all the time and after treating most of the areas in the car, I still get road noise in the cabin! what kind of noise:

Engine Noise

Wind Noise

The little Motor from the Windshield wipers

So I took off the wipers, lift the plastic cover and exposed the wipers motor system on the pilots side and a big opening into the cabin (COWL TO REGISTER DUCT SUB-ASSEMBLY), where the air goes into the interior air filter.

I knew that engine noise will hit the hood and travel up ward towards the windshield and the glass will transmit the noise inside, I'm aware of the wind hitting the windshield adding extra noise, but inspecting this area it's like a long channel made of very thing metal between the engine and the fire wall, right where the windshield begins and it goes from side to side (COWL TOP PANEL OUTER). See images below...

So I started adding some thick MAT (little peaces of CLD Tiles) along this channel, only in the inside, to prevent from reverberating due to the engine noise and transmitting that into the cabin via the windshield and the big opening for the fresh air that goes inside the cabin.

2 issues to resolve, "water" and "air flow" I can't really sealed. I start cutting small pieces of MLV the biggest one with a long shape (see picture below) and just lay it down on the passengers side, I cut 2 smaller ones for the pilot side that I slide under the wiper's electric motor, one more piece of MLV slightly bigger than the opening for fresh air, I cut 2 small triangles on the top side to prevent blocking the air flow.

Doing this I just hit 3 balls in a row, Engine noise, Wind noise, and wiper's noise. I know it's not completely sealed, but it doesn't need to, think MLV as sound barriers like the ones along highways, big solid walls blocking transit noise towards houses along the road.

The end result, a big change, why I didn't do this before, it's so easy and effective!

Re-cap...

FRONT STAGE HISTORY...

1st image: very narrow stage, image no good

then...

2nd image: better image but still narrow stage

and now...

3rd image: sweet!


1: very narrow stage, image no good


2: better image but still narrow stage


3: sweet! the BEST so far for me.

I can say that I've come to the same conclusion. The height on the second setup is probably the best...or at least how I had mine was. Still though, the trade off leans me more towards the third setup.

I don't miss the height, because it's up there! I would never go back to mids on a-pillars, at least in a Yaris.

How is the new HAT woofer?

I'm doing a demo tomorrow.... another P99 owner with Focal speakers mmm... we'll see!

D.

[sqcomp]

The new woofer is going to tooling soon. We should have a test mule in a month or two for testing.

If this had been a competition, guess who WON!....



ps....
That's him: p99rs, boston acoustics gt-5750: focal 165vrs, seas tffnc/g and focal sb25a1; rockford fosgate r150-2: tang band 1362sa

...I'd bet you you'd be even better with an SE midrange in there...

I wish I could be there mang. Still, I have complete confidence in what you're doing D. I also wish you could be down at Spring Break in Daytona over the weekend of the 23rd. There's going to be world class systems going head to head in competition. I know you'd dig that.

Was it Focal's shallow mount Polyglass line component mid bass you were listening to? A Boston Acoustics 5 channel (75 x 5 & 250 x 1), a preloaded Focal woofer, a SEAS tweeter, What was the Tang Band and the RF amp for?

I know L3SEs is what I'm missing now, to be a complete HAT system. (some day!)

I wish you where here too, you would be proud of me! I wish I could go to Daytona, but... that's the price I have to pay for 2 beautiful children that keep me and my lovely wife very busy. (O:

I think he had the TB on the doors, the 3" Focal and SEAS tweeters on PVC pods up on the a-pillars, and 10 in Focal woofer in a ported box in the back, Yes 2 amps the BA and the RF, on a 05 Toyota Matrix.

I had this asked many times in other forums, and I would like to share here:

Lets talk about deadening a car:

Ok, first lets recognize there are 2 types of deadening, what is your target?

1.- a system to Block noise (road, engine, wind, rain, exhaust, etc)

2.- a system to reduce rattles and condition a car acoustically (also helps to reduce road noise but not as effective as #1


To accomplish 1, you need:
-CLD Tiles (expensive) you only need to cover 25% of the area this prevents vibrations
-CCFoam 1/8" or 1/4" works good, this helps absorb high frequencies and prevent rattles
-MLV, mass loaded vinyl, to block the noise

To accomplish 2, you need:
-inexpensive MAT, 1 or 2 layers of 100 coverage is common. You can use expensive stuff too, but that is up to you!
-CCFoam 1/8" to prevent rattles and smooth edges

For example, I did #1 on the floors and wheel wells,
I did #1 on the rear doors (no speakers there)
I did #1 and #2 on front doors where my Mid-Bass speakers are.

so... what would you like to accomplish?

Here is some good reading:
