Soundproofing Saab Cars To Quieten Road Noise

Many people know the sound performance of speakers will improve if there are car soundproofing on whole car too. The sound also becomes very clear as the traffic noise, wind noise and tyre running noise are all dropped to a minimal level. Also, the atmosphere in the car will be much better if there is as little noise from outside.

Many people has lack of soundproofing knowledge that make them not confident to do car soundproofing installation for their cars. Simply because they are afraid of money spent without good noise reduction effect. In fact, this is very true that people do waste their money that won’t create an obvious effect that they can feel after the installation.

there are many good soundproofing solutions on the market and most are based on multi-layered car lining with special noise reduction materials. One such solution is StP by Standartplastand in the following example we can see an applied solution of a Spanish studio that on the Saab 9-3 did a demonstrative reduction (soundproofing) of cabin. The “Standartplast”  was established in 1996 as a scientific researcher in the field of acoustic integration, and for more than twenty years, STP has been offering comfort, safety and acoustic advantage to its customers.

This Saab 9-3 1.8t has been completely soundproofed except for the roof with StandartPlast materials, the best in the market.

The first layer (StP Aero) has been applied to the entire vehicle sheet from the inside. This first layer eliminates vibrations from drive rolling and engine for example. Therefore in this way we reduce much of the road noise caused by vibrations.

The functionality of the second layer (StP Accent and StP Biplast) is absorbing both sound and cold and heat, therefore we have applied StP Accent on the entire floor surface as well as the second layer inside the doors. In the wheel arches we have applied the highest range of StP, the Biplast Diamond Wave 15, which promises to be the most efficient in terms of sound absorption, and the truth that has pleasantly surprised us. We have also used this material in the door panels, thus achieving surprising exterior noise insulation.

The third layer is StP NoiseBlock and is only determined on horizontal surfaces or with few degrees of inclination, since it is a material that has a high weight and although the adhesive is very strong, it could reach a peel off on vertical surfaces. This layer is made of asphalt cloth and almost completely blocks the sound from outside. It is important to know that it works together with StP Accent or StP Biplast, since it requires that some of these materials attenuate the external sound and avoid contact with the metal sheet to perform its function. Conclusions Worth it? Flatly yes. The reduction of outside noise is very impressive, and even more so the road noise. According to the measurements, the road noise has been reduced 18dB (+6dB is double of the sound sense).

Costs

The total cost has been approximately $ 500 (Floor + wheel arches + trunk + 4 doors), and this Soundproofing installer are located at Spain (Barcelona) Parets del Valles.
