    Guys,

    I just downloaded and installed a free decibel meter app on my windows phone and was curious to check the noise levels of my Jet. Here are the results:

    Bonnet open and cold engine cranked - 76 dB
    Bonnet open and engine warmed up - 65 dB
    Bonnet closed warm engine - 60 dB
    All doors shut, Music off - 52 dB

    Yet to do a drive and see how much noise when driving at various speeds.

    For reference here is chart of common noises:

    It's cool. It's a simple and rudimentary (not the most accurate) method of comparing the noise level of our cars.

    I'll do the same and post up later. Both Linea D and Palio D. Palio D cold start should rattle the decibel meter nicely. :mrgreen:

    Cheers.

    Maybe you could use this to measure the much talked about wind noise :)

    Interesting :-D , let me download one for my S2 and see what it shows


    I think i made a note of this a few days back after my trip to Himachal , there was no wind noise at the speeds i was at , maximum was around 130 and the only noise was the road / tyre noise.

    So i downloaded the DB Meter on my Windows Phone
    All tests inside a closed garage.


    Cold Start Idle for Linea MJD with 82K on Odo-74-75 DB with Phone placed on engine cover.

    No offence. You have posted a picture of a proper decibel meter, that you say you own. But you cannot be bothered to measure the noise levels in your car and post more accurate readings than what we poor folks have to be satisfied with, using a free app.

    Pray, may I ask, why bother to even post?

    I dont mind.

    I don't have a picture of same right now as I am out of India.

    Alright I went bit overboard,forgive me.

    db meters are weighted they have their own deficiencies.I find it pointless to post the db measured in limited bandwidth of say 100hz to 5khz,where I can hear lot more than what sound meters are blind to. one of the worst is infrasonic frequencies which makes some of us puke or abdominal issues in the run.

    Being an Audiophile I have many other methods of measurement as well which would be too weird here I guess. like a dedicated spl (sound pressure level) response measurement system which can measure from 10 hz to 100khz where comparatively Db meters give only vague values which are very polar.

    I have a glove-box light in my punto. :)

    Here's how noisy the Palio D is. As per a free app on my China (Chaena) phone. :p

    Cold start idle :

    * Standing outside, Bonnet closed, phone near it -72
    * Bonnet open, phone near injection pump - 77-78
    * Sitting inside, blower off - 56
    * AC on, blower at Speed 3 - 61
    * Cruising @ 70kmph with blower at speed 3- 70

    Same figures after engine warmed up.

    Will update this post with Linea figures later on.

    Cheers.
