road noise

[meleagant8]

bad trip nga....putcha, ang dalas ko madisgrasya sa mga pako, turnilyo etc....

ngayon lang, merong mahabang pako na punasok sa gulong ko...lumabas sa sidewall...sana di tinamaan sa loob....

uy cliffjumper, naka sounds set up ka na ba?dapat ba naka sounds set up bago maglagay ng mga acoustiofoam?

[theveed]

ubod ng ingay ang NCT3... as in sobra... para kang naka tube na gulong na malaki... bad trip...

change your tires... also, while waiting for your current set to wear out... always check the tire pressure... laking ingay kung mali pressure mo.

don't know why local goodyears suck so much...

[cliffjumper]

meleagant8.. di pa ako naka setup, plano ko talaga sana kaya lang napurnada yung pera ko sa mmg.. ipon muna ulit ako. My main purpose in installing acoustifoam is to reduce road noise. pero i heard na mas gaganda ang output ng set up mo kapag naka acoustifoam. siguro mas rinig mo yung crispness ng sound dahil walang masyadong road noise na kalaban.

boss theveed.. your right. daming bad effects kapag mali tire pressure (either over or underinflated). road noise, bad fuel milage, bumpy ride etc.. kala ko nga dati sira yung shocks, yung pala overinflated lang yung tires ko..

[theveed]

reducing the noise floor of your car will increase your sound system's efficiency on transferring clear sound to your ears...

yun nga lang, bibigat ang kotse mo hehe

[boybitz]

using visual inpection, pag tama ang tire pressure, how much of your tire should be on the floor? Kunwari pag flat d ba halos buong diameter nya nasa sahig. e pag ok, mga ilang inches?

[theveed]

you can't visualize proper tire pressure... there's no way unless your eye is keen enough to see 1mm of lift or whatever... Just get a decent tire gauge...

hey gonna revitalize this thread!

Im planning on dynamatting my 2nd Gen CRV from what I've read. Only all four doors though cause I have no problem with engine noise.

I have set up my sound system and noticed that there is only this thin plastic on the doors with white goo. Do you think dynamat would make a big difference on just the four doors, or at least something noticeable?

[Blackbird]

does anyone have any feedback on the Goodyear Ducaro GA tires? they're supposed to be quiet daw...

wala na yata kasi nung Bridgestone Turanza GR-50 SS eh... or if ever, walang available sa size na kelangan ko 185/70/R13

[morrissey_05]

sorry to resurrect this old thread. but the road noise is driving me crazy.

pls tell me if what im doing is right: planning to use flashband on the doors, in case i want to have good sounds later on. maybe only a layer or too. for the floors, acoutifoam.

another question: where do i buy acoustifoam? been too handyman in rob manila pero wala daw. same sa true value shang. or should i specify han gang brand?

thanks all for your inputs.

morrisey, nakabili ka ng flashbands? acoutifoams? san ka nakabili? ako rin, plan ko maglagay.. pero may nabasa ako na dapat hindi asphalt-based un mga ilalagay, kasi daw madali matunaw especially dito sa pinas na super init.. baka bumagsak, specially kung sa ceiling ilagay.. i need to confirm kung asphalt-based ba o hindi ang flashbands..

[simplicity]

asphalt based ang FlashBand. even the one i used - FlashingTape - is
asphalt based. pero hindi naman bumagsak or anuman. mas ok pa nga
daw siya kesa sa FlashBand kasi kelangan mo pang i blower or heat
gun yung FlashBand para dumikit. yung FlashingTape ni-roll ko lang using AA size na battery.
btw, kelangan mo lang linis ng mabuti at patuyuin yung didikitan mo.
what i did was clean the driver side door first then tinutukan ko ng
electric fan while i was cleaning the passenger side door. nung tuyo
na i let it stay for a while pa ra mas sigurado akong tuyo na.
(open doors)

[kooldud]

naglagay ka rin sa interior ng door? or dun lang sa may door panel? naglagay ka pa ng matting on top of the FlashingTape? or kinabit mo agad un door panel? sa door ka lang naglagay? isip ko nga rin FlashBand (or similar) un ilalagay ko, para mas mura.. pero sa RAAMMat, ang prob daw sa mga asphalt-based, pag tumagal, natutunaw dahil sa init.. tapos mabaho daw.. un RAAMMat ata ngyn, door kit lang 4k na..hehe mahal...

the road itself does not make noise. it is your tires on contact with the road and your suspension insulators that transmits vibration and noise inside the cab. start with cruising tires. even a lexus sedan will make noise if you use the wrong tire. then, check your suspension rubber bushing for wear and age. if they are not firm and pliable anymore, it might be time to replace them. long before rubber insulators (bushings) were installed on the suspension, they used metal to metal, that's right, metal to metal flex joints on the lower control arms. they transmit noise and worse if not lubricated with suspension grease an additional squeakiness (specially ford) happens. in the late '70's, the suspension were insulated and even the engine noise isolation was beefed up by the additional rubber insulation on the engine/transaxle cradle to further isolate noise, vibration and harshness (NVH). with your car, again start with the right type of tire with the correct air inflation pressure. nip the problem at its cause or origin similar to spraying air freshener in the room without removing the dead rat, would still smell dead rat
