Honda Fit, noisy

Discussion in 'Fit' started by Andrew Murray, Apr 14, 2007.

  1. Hi. Just test drove the Fit. Really liked it, very peppy for small engine,
    but really noisy. Anybody know of good way to inulate passengers from
    engine noise, without overheating engine.

  2. I use carpet padding under the carpeting. I usually do this on old cars,
    since if there are any holes the padding will get wet. We don't want that

    Or, you could get something like DynaMat. You have to remove the interior
    and put it under the carpet and behind the door panels.

    The thing would be as quiet as a Cadillac!

    1) fit a bigger muffler ; Lexus has a very big muffler
    2) find ways to incr spark size (i) disable useless drain of current
    e.g. bypass windows' motors relay, or diasble internal EGR's
    valve & solenoid, (ii) use copper wires to conduct heat out of
    transformer coils to get more amperes ; faster combustion
    can really cut exhaust noise

    You wish.
    In my experience sound deadeners work wonders for stopping rattles and
    increasing bass tenfold but they don't do a dick
    to decrease road noise. You get what you pay for.
    If peace and quiet is high on the shopping list I suggest
    to pay for a luxury or a near luxury car.

  5. I put foam carpet padding in a Corolla and the quietness was

    Like an Accord or Camry.

    My 07 is notably quieter than the 04, which was already quiet, and
    generally the Camrys are quieter yet.

  7. Chea, all you have to do to reduce the noise is to take those pills
    that make the voices in your head go away.

    Okay, you managed to treat the window glass too???

    I still don't understand how that would help with the ENGINE
    noise the OP is drying to drown. You can treat the floor all you want
    and I might even believe it would drown the cacophony of pebbles
    on an unpaved section of a road but how would that help with the
    ENGINE noise? To drown the engine noise there are two options:
    1. Treat the firewall with prodigious amounts of sound deadeners
    (including liquid ones because firewall is a bitch to get to
    and a bunch of piping going back and forth thru it does not help)
    2. Install a quieter engine (such as a six or an eight) and operate
    it at half the potential at low rpm.

  9. Well, the overall level of noise in the car came down immediately.

    What happened was, the car was stolen and gutted on the interior. When I
    got it back the carpeting was still there, but the seats, console, etc
    were all removed. I removed the lower part of the dash and the carpeting,
    laid the carpeting out on the ground and cut the carpet padding in
    patterns to match the carpet. This covered the entire floor panel from the
    top of the firewall all the way to the back of the car ('85 Corolla Hatch).

    I used 1/2" padding with a 'vapor barrier' on one side, and put the vapor
    barrier towards the floor. The car was incredibly more quite then it had
    ever been before. I was amazed. I had bought the car in '86, so it wasn't
    like it was new to me. I did the rebuild in '91, so I was well familiar
    with how loud the car was.

    Interior noise levels are one place where Honda doesn't do a great job.

    Professional undercoating helps quite a bit to reduce road noise and
    also damps the conduction of engine noise through the floorpan.
    John Horner, Apr 18, 2007

  11. But can also lead to trapping moisture and causing premature rusting.

    I bought a Corolla in '86 from the Service Manager at a Toy dealer. He
    didn't undercoat it, and I asked him about it, and he shot back at me,
    "You want it to rust?"

    That car went the longest without rust of any Toyota I had previously and
    had undercoated.
