Ways on How to Make Your Car Quieter Inside

1. Inspect the car engine

Checking the state of your car should be your first priority when you want to make the car quieter. The first place you should start is the engine.

The engines are designed in such a way that they can make a little bit of noise, which is not bothersome.

However, when the noise is loud enough to cause annoyance inside the vehicle, then there is a problem.

Most engine noises are as a result of dirty or the incorrect oil. So, you should check on that using a dipstick.

If the stick is not visible through the oil, then its time you change the oil.

Also, if you are using mineral oil instead of synthetic, then that could be the cause of the noise.

As you check for the oil, also check whether the engine parts are okay. Worn out parts can create noise when the car is in motion.

Change the oil and fix any damaged parts or take your car to the repair shop for fixing.

2. Check the Suspension and the Exhaust Pipes

Consider also checking the suspension and the exhaust pipes of your car. The suspension parts include shocker bolts, steering ends, and the ball joints.

These parts are prone to friction if they are not lubricated enough. Therefore, you should get the right lubrication for your car and grease it occasionally.

The exhaust system is also prone to rust, which may damage its parts if not checked regularly. Also, the type of exhaust pipes that you use contributes to the noise inside your car.

If you are using a free flow muffler, then that could be the cause of the noisy car. If you want silence, try using stock exhaust.

The first step to fixing a noisy car is by installing sound deadening mats. These mats are made of soundproofing properties that muffle the noise inside.

Installing the mats is an easy job in which you can do a DIY project. All you have to do is remove your car’s floor mat then install the new mat.

Sound deadening mats come with their own adhesive, which means you won’t waste money purchasing a new adhesive.

When installing the mats, remember to clean the floor first; otherwise, the adhesive won’t stick.

You can cut the mats into patches and install them in all the areas where noise is leaking.

The best thing about these mats is you can install them on any surface that leaks noise inside the car.

Areas such as the hood, the trunk where the noise leaks from the wheels, and the doors should be soundproofed.

Sound deadening mats are effective and quite affordable if you are worried about the budget.

However, the best sound deadening mats according to most online reviews is the Dynamat.

The mat is quite pricey compared to others, but it is effective at minimizing noise. But if you can’t afford it, you can try FatMat sound deadening mat.

While installing mats, you can also add a weather strip in case the one you have is worn out or damaged.

Remember, even the tiniest of the gaps can leaking too much noise in the car.

4. Upgrade car tires

Consider changing your tires to something with a better and softer material that has a higher profile.

You can change the car tires yourself or have a professional do it for you.

Once you change the tires to a softer material, you will notice the changes in the amount of noise getting inside the vehicle.

You may also coat the tires with rubberized undercoating. When shopping for the coating, ensure you purchase from authorized sellers.

5. Try Soundproof Sprays

You can also use soundproof spray t to reduce the noise inside your car. The soundproof spray makes the application of insulation easy when sprayed in hard to reach areas.

These hard to reach areas makes it harder when you are installing sound deadening insulation. The spray works by absorbing sound waves inside the car.

Here are the steps that should help you when insulating the car with spray sound deadener:

The preparation. You need to clean the areas in the car where you want to soundproof.

Start by removing rust, dust, and any unwanted substance in the vehicle.  You can use a rust encapsulator to treat the rust.

Get the necessary materials. Purchase spray nozzle, mixer, spray gun, among other things.

Make sure you wear protective clothing for your safety.

Once you have everything ready, then you should start applying the sound deadener. Ensure you are at least eight inches away when you are applying.

Give it 20 minutes for the paint to dry up before applying another layer on top of it. Repeat the process until you have three layers of the paint.

Once the paint has dried up, return everything to its place. If you had floor mats and sound deadeners installed, you can return them the way they were.

The spray is effective and easier to use, even if you don’t have any experience.  It can be used alone or combined with other soundproofing products, but either way, they work effectively at minimizing noise.

The soundproof spray is also affordable if you are worried about the budget.

6. Use Reflective Insulation

Reflective insulation is a good example of a product to use when you are thinking of minimizing noise in a car.

The insulators are mostly used to minimize heat from the floorboard.

The insulators are placed beneath the mats for effectiveness.

7. Ask for a Professionals Help

Finally, if you have tried all the options and even checked the vehicle, then its time you thought of other ways.

Consider getting a professional’s opinion for the noisy car.

Your comfort is paramount, even if you will have to spend more money to have your car fixed.
