Please take note if you are the owner of SAGA LMST !! Don't simply cut your door panel and door trim, because this kind of car door trim is too weak and the internal structure was unsatisfactory. Therefore, please think wisely if you want to cut the door panel. You are being advice that go to the experience workshop to do the modification

SAGA LMST door panel re-modify

it's too weak about the door panel, need add a soundproof vibration damping

after StP vibroplast soundproof

after vibration damping , add another layer of contact damping

door trim also need soundproof with 2 layer

HOW MUCH U KNOW ABOUT SOUNDPROOF ? JUST READ IT

mr.wong — Sun, 13 Mar 2011 18:51:03 +0800

Before i upload the picture and share my knowledge, i wanna specially thanks to Mr.Dmitriy ( StP's technical consultant) who come from Ukraine,and teach us wat to do can Efficiently to reduce the car noise and improve comfortable in our car. Thanks to Mr.Dmitriy

MR.DMITRIY picture

Mr.Dmitriy is come fro Ukraine, he is a Acoustics Engineering, specially in Physical Acoustics, so he is a professor in Acoustics Engineering. Now work as a Technical Consultant in Stp. Before he work as a Technical Consultant in Stp, he is a experts in Car Audio System, he won alot of champions in EMMA, ISACA international competition.

Mr.Dmitry said : If you wan to get maximum effect use complex of suitable materials for each surface and follow " Applications instructions. Acoustic Materials" . Different materials are different effective.

3 catagories of soundproof :

a) Vibrations Damping Materials

- Reduce the low frequency noise (50hz - 1000hz)
- absorb / reduce the vibrations

b) Sound Damping Materials

- Reduce / Absorb / Reflect the mid high frequency
- Reduce wind noise, road noise and heat insulating properties.

c) Contact Damping

- Absord mid to high frequency
- Required to eliminate squeak of the contacting element of interior and also for joint sealing

Only use a suitable materials of soundproof, then just can efficiently to reduce the noise. If not。。。。。just wasting ur money

Mr.Dmitriy was explained the door strucure and vibrations caused by mechanical movements.

Explained that where is the noise come from

Use a dry cloths clean the surface

Measure the size of the door

Using the Stp BiMast Bomb to reduce the door vibrations and noise
