Additional Car Noise isolation

Car noise refers to the sound vibrations produced by a car when the vehicle engine is running. There are different reasons for car noise ranging from poor noise isolation by automotive manufacturing companies to aging of the vehicle.

In order to reduce the amount of noise in your vehicle there are several measures one can take. Begin by ensuring your automobile is well serviced, old cars have multiple mechanical problems and loose parts which increase the number of vibrations inside and out. Mechanical problems can be a loud source of noise. An exhaust muffler may be an appropriate measure to insulate exhaust noises. There are certain tires that also cause vehicle noise which can be reduced by changing the tires.

Once you have reduced the mechanical noise to the lowest level it is time to isolate the interior of the vehicle from noise. This is easily achieved by the following measures. Start by using various damping materials that absorb sound waves and vibrations. They include damping mats made of a special kind of rubber used to cover the vehicle panels and insulate the sound. The principle holds that the added weight on the panels by the damping mats helps to reduce panel vibrations. This material should be placed between door panels which are close to each other to reduce their vibrations and within the engine compartment to deaden the rattling sounds.

One may also use foams instead of damping mats. Foams are much lighter and tackle the noise problem to a considerable extent. Foam sprays serve the same purpose. This is achieved by spraying foam into the small spaces along the panel, in the engine and around the doors to create sound absorbing joints that disperse vibrations.

There are also paint sprays that are used in areas where the mats are too bulky to use. The vibration of metals is usually very high. Take for instance iron sheets, even when blown by wind the rattling produced can be deafening. Note the effect paint has on the iron sheet, it makes the sheet heavier resulting in reduced vibrations. This is the same effect paint sprays have on the car and vehicle parts that produce noises. Paint sprays can be applied evenly around the entire vehicle using different colors in different areas. The advantage is that sprays can be used in almost all areas of the vehicles and can cover areas that are difficult to reach by other means.

Use of insulation can also reduce car noise. Placed underneath the interior carpet of the car, insulation actively absorbs sound waves. Although the sound absorption of insulation material is significantly low, it doubles as a heat absorber as well as a cushion of the interior carpet. If you are planning on insulating your vehicle yourself begin by taking the correct measurements of the desired areas. Cut the insulation according to the specific measurements and start removing the interior carpet. Apply the appropriate contact adhesion to the body of the car along the desired areas and carefully place the insulation on top of the adhesive. Press the material firmly over the adhesive to ensure it sticks strongly. Follow up with foaming spray to cover crevices that may have been left out and allow them to dry.

It is impossible to  completely isolate sound from a vehicle but having followed these steps you will have significantly isolated noise from your car. Try these measures and enjoy the experience of driving a noise isolated automobile.
