In terms of how you can reduce the noise in your world, exactly what noises you are trying to reduce will have an effect on how you can create a quieter environment.
When you are looking specifically at reducing the cabin noise of your vehicle, whether to make a quieter ride or to improve the audio quality from your sound system, there are a lot of options you can look into.
When you are reviewing different products that say that are going to solve the noise problem that you have, you need to understand the terms they use. Although many products are advertised as ‘soundproof’, this is rarely what they truly mean.
What Is Sound Deadening?
This is a term that you will most often see associated with vehicle noise. When people talk about sound deadening properties, they are usually meaning ways in which they can reduce the noise inside the cabin.
This may mean reducing the shakes and rattles from loose fittings or things that roll around in the trunk, through to decreasing the road noise that permeants through into the car’s interior. There are a lot of product that can be used to help you achieve a quiet drive, have a look on here for more ideas: https://soundproofpros.com
Removing rattles can be just a case of hunting them down and making sure that everything is tightened properly. However, generally, you will need to look a little more into applying a sound deadening product.
What Is High Tack Permanent Adhesive Sound Deadener?
There is a range of products that can be placed inside your doors that will help reduce road noise and rattles. Generally, they will come in an adhesive sheet that can be cut to fit your door.
Remove your door panel, then just follow the instructions for your brand to stick the sound deadener sheet to your door, then replace your panel. It is generally easy to apply to contoured areas, so it can also be used on your roof, trunk and wheel housing.
Some people have successfully used this type of product on their floor, under the carpet, to reduce road noise, but there is a range of products that can be used specifically for this purpose.
An added advantage of using this type of adhesive product is that is will also increase the insulation of your vehicle. This generally will save you fuel costs from running air conditioning but will just generally produce a more comfortable ride.
If you do install this product, make sure that you are using something that has been specifically designed for use with motor vehicles rather than for another purpose such as home soundproofing.
Check that it has a fire rating suitable for use in your car, and is waterproof. You do not want a product that will attract moisture from being against a cold metal exterior as this will obviously potentially cause serious structural concerns.
Under-Hood Thermal Acoustic Lining For Engine Noise
This product is designed to reduce engine noise and minimize engine vibration. As an added advantage its insulating properties can help protect your custom paint job from premature fading and cracking. This is more noticeable if you have a high-performance engine that produces a lot of heat after running for a while.
You could potentially use this product for generators to reduce the noise that they produce.
Some of the options for this product will come with aluminum coating, so you will need to confirm that this will not interfere with any computer system or other electronics that you have installed in your vehicle.
Spray-on Sound Deadening
While this is still a relatively new kid on the market, there is a range of competing brands bringing spray-on products to the automotive industry.
Basically, this work as you’d expect. You have a spray can full of the sound deadening liquid that is sprayed on to the surface of your car. It can be used instead of adhesive matting, or it can be used alongside – saving you the pain of having to ensure that all the little corners are covered by adhesive matting.
A very similar product that has been around for a little longer is a spray-on rubber, which also has noise reduction properties. Noise reduction is a large market, so much research is consistently seeing new developments (see here).
One of the advantages of this product is that it can be painted on. You can also layer it up, meaning that you can reapply if the sound reduction is not at the level you want it at after the first, or second, coating.
Most of this type of product can also be painted on with a color topcoat, although you will generally need to allow at least 6 hours for each coat to harden. If you are planning to use a spray-on product near highly flammable or high heat areas, such as engine bays or around mufflers, you would be wise to consider using a high heat resistant paint as a final coating.
Do Speaker Baffles Do Anything Useful?
This will actually depend on the quality of your speakers, but for people who are looking at reducing frequency vibrations in the car, you probably have replaced the standard sound system that came with your vehicle when you bought it, with something decent. https://electronics.howstuffworks.com/gadgets/automotive/car-audio-system-sound2.htm
Speaker baffles can help to isolate the sound from speakers in your car doors, giving you a cleaner sound, more focused direction, and less bass escaping and vibrating around the door panel cavity.
The added advantage of using a speaker baffle unit is that they help to protect your speakers from water damage if your doors leak or develop condensation – and doors actually develop quite a lot of moisture internally.
Speaker baffles will alter the audio quality and frequencies. Generally, this will be a positive effect, however, for some systems, and for particular musical styles, the altered quality may not be a desirable effect.
Some research into the type of baffle and reviews before you go ahead and make a purchase would be a good idea.
