Things to Consider Before Buying the Best Automotive Sound Deadening Material
Sound deadeners come in different sizes, brands, and materials. Different brands have their own unique features. It can be quite tricky to decide on the deadener material to buy However if you’re well informed about what to look out for, then you’ll most likely make an informed choice. With that said, here are the things you should consider when buying a sound deadener.
1. Method of Noise Isolation
Before you make a choice, you should know the method of noise isolation that the material uses. First, you should know that soundproofing is not the same as sound absorption. A soundproof material minimizes outside noises from entering the car. Such noises include traffic noise, wind, the humming of the tires, and road vibrations. Thus, if most of the noise is coming from outside, a soundproofing material will work better.
Materials that absorb noise usually absorb noise from within the car such as rattling off the trunk, loud motor, and cabin noise. If most of the noise in your car is coming from the inside, then you should go for a material that absorbs noise.
Nevertheless, you can also combine the materials. For instance, you can use sound-absorbing materials on the cabin and trunk and use soundproofing material on the doors, roof, and floor.
2. Type of the Insulation Material
There’re different types of materials used in making sound deadeners. They absorb or insulate against noise differently. Knowing their differences will assist you to know the ideal sound deadener to use in different areas of your car. The main types of noise insulation materials include:
- Damping Mats- These mats are most common and are ideal for application on panels.
- Insulators- They’re usually made of fiber cloths. They’re ideal for absorbing noise from beneath the car carpets.
- Foam- Foam is most efficient for deadening reverberations in the cabin. Foams are generally available in form of sheets.
- Sprays- Sprays are suitable for application in areas where mats cannot be used. They’re the least common noise deadeners.
3. Thickness of the Sound Deadener
It’s obvious that thickness matters a lot with regard to insulation against noise. Thicker materials are better at deadening sound than thinner ones. You can even use multilayered material for enhanced sound deadening.
4. Size of the Material
Different sound deadeners come in different sizes. The size you should buy should depend on the extent of the area you want to insulate. Some of them come as rolled mats such that you can cut out the size you want. Others come as pre-cut sheets. The size of the sheet to buy should also depend on the area to cover.
5. Oil Resistance
Car bodies are always in contact with oil. Even if you’re very careful with oil and grease, and you keep your automotive clean at all times, you will not escape from having some oily car surfaces. Thus, you will want a sound deadener material that can stick to any surface, even if the surface is oily. Hence, investing in a sound isolation material that sticks on oily surfaces will be a plus.
6. Weight and Flexibility of the Material
Different deadeners weigh different. Preferably, go for lightweight material for easier installation. Lightweight materials are easy to fix since you’ll not use much energy and effort to fit on any surface. Highly flexible material will allow for easier installation. You’ll easily bend it around irregular car surfaces, something which is very common in cars.
In conclusion, it’s clear that there’re many types of sound deadeners to choose from. Avoid choosing a material based on price alone. Choosing a material just because it’s cheap may lead you into choosing a low-quality sound deadener.
Again, an expensive material doesn’t necessarily mean that it’s the best. Thus, the balance between price and quality. Hence, consider other factors such as the size of the material, thickness, flexibility, and method of noise isolation among other factors mentioned previously. By keeping this guide in mind, you’ll automatically stand a better chance of getting the best automotive sound deadening material.
Also, don’t forget that each material comes with its own unique benefits and some shortcomings. Thus, invest in the material that offers the kind of features you want and the shortcomings you can live with for the best sound isolation in your car. That way, you’ll enjoy enhanced music in your car while being in a more comfortable car environment.
