Topic: How quiet is your car?

[safristi]

as a comparison BUNNY FARTS are rated @ 0.001dB...................


 and that annoys me when i'm resting......................

I have the same app so I'll give the Sebring a try this weekend.

Interesting topic, don't remember much discussion here about interior noise in terms of empirical data.

Initially I was thinking that since dB is a logarithmic scale that a 3dB increase in background noise would be twice as loud. However, I did some reading that suggested that a 3dB increase barely perceptible to the human ear.

Curious if anyone has any experience in this field to educate us one how much of an increase in noise level is really significant.

What is WFO?

I'll do a test this afternoon. I hate driving on American Interstates, so freaking loud!

WIDE FACKING OPEN!!

I read the reviews on that app and the permissions - it wants wifi state and network state so I assume advertising?

There seems to be varying degrees of accuracy, i.e. 50db in a quiet room with no noise and a maximum of around 80-90 or so no matter how loud.

App, my system pumps 120 db of sound that I know for a fact (EPA and police measured) 5 metres outside my house , yet free version measures up to 80. Uninstalled."

Another app - "Noise Meter" has no advertising or permissions needed but has the same high rating with no noise and max of around 80-90.

So I didn't bother.

On the other hand the critical levels of over 85 db if measured incorrectly could damage your hearing.

From what I read somewhere - at higher levels - that 3db increase cuts the time in half that is safe.

i.e a rock concert or jackhammer at 100db is dangerous and has a maximum safe time. 3db more and that time is cut in half.

^^That's flat out wrong.  We have a a VERY expensive meter here at work as I said earlier, and I tested it right beside the app.  The "real" meter read 88....the cell phone app read 88.  When I walked outside, they were also both identical (about 60).

^^^ I guessed it was accurate based on what you wrote - up to 88db - but what about higher?

They seemed to suggest there may be a hardware limit of around 90.

Hang on...let me go pound a pice of steel with a hammer and see what number comes up....

**EDIT**  I got up to 94 dB pounding a large hammer on some steel.  I may have been able to go higher, but it was clear I was starting to annoy my co-workers...

What? My ears are ringing.

Do some more and compare so we can rely on 100db accuracy.

With all this talk of how quiet teh Verano is, I'll test it when I go out this evening.  I forgot on my way home.

Heheheh.....my co-workers will go insane.  I don't need it to be accurate for 100+ dB.  As I said...although it might not be EXACTLY as accurate as a professional meter, it's pretty darn close...and close enough to use in a much quieter car.

I just installed the app and whistled into the microphone and it hard stopped at 90 on my nexus.

I actually have a professional DB meter around here someplace, I bought it when I was doing stereo installs.  But I to have compared it to apps on phones and they are identical.

Of course the meter offers more features and averages.

I'm not sure if I can screen grab a momentary burst.......??

**EDIT**  I just got it to 92....but on the min-max scale thing it stopped at 90.....Hmmmmmm

[wing]

whatever, I'll report back around 7:30 or 8 with my result.

32 off sounds right.  65 at idle, huh?  Not exactly quiet.

Just downloaded the app I will test the Berlin taxi tomorrow.

As a baseline my wife is 65 db.
