[DailyDriver]

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.

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.

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.

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.

It's hard to have a sense of scale with db (decibels) so I thought about what if I open the window at 80mph? almost 10 db more, but to my ears it was twice as much louder. It's interesting how these measurements work, we are used to grab a ruler and measure, but with decibels I guess it doesn't work the same way.

the dB scale is exponential. either 0 or 1 dB is supposed to be the lowest volume of sound a human ear is supposed to be able to hear. Every increase of 3dB is technically a doubling in volume. HOWEVER, human ears suck as listening tools. Human ears usually perceive a 6 to 10dB increase as being a doubling in sound.

So, you saying that a 10dB increase felt like a doubling is within normal perception.

Also, once you start getting up past 120dB, the ears really can't tell what a doubling is... especially when you start getting in the 140+ range.

Another thing, there are many different decibel measurement tools out there. I know of only one that is accurate & consistent regardless of environmental conditions. Many are very liberal with their ratings (higher readings than they should be).
