How to Make your Car Quieter inside in 7 Simple Steps

In this guide, you’re going to learn how to make your car quieter inside as Rolls Royce. Did you know that Rolls Royce cars are ultra-quiet even at 125mph? But these cars are damn expensive.

The noise entering your car cabin comes from different sources. They include the tires, the wind, and the mechanical components of your car.

Whenever the tires tread come in contact with the road, you can hear some sounds they produce. The larger the treads of the tires are, the noisier they are.

Mechanical components of your car include the engine, the exhaust, and others. When the engine and the exhaust systems are faulty, the car will produce some noise when driving.

And while it’s impossible to achieve Rolls Royce level of quietness on budget cars, you can still make the cabin quiet as cricket. Below is a detailed guide on how to make your car quieter inside.

How to Make your Car Quieter inside

First, let’s understand the four kinds of noises that leak inside your car’s cabin. They include:

  • Wind noise
  • Road noise
  • Engine noise
  • Exhaust noise
  • Suspension noise

1. Use Sound Deadening Materials to Reduce Wind Noise

Wind noise is unavoidable at high speeds. Less aerodynamic cars, for example, SUVs, suffer the most in this case.  Fortunately, you can reduce road noise by addressing certain areas.

Most budget cars have doors with poor sealing. This leaks in a lot of wind noise. One of the best ways of addressing wind noise is by adding door weatherstripping to the door frames.

Adding sound-deadening materials to your car’s floor, doors, and the roof lining can help you reduce wind noise, especially on less- aerodynamic cars.  Sound deadening material is an excellent product you can use in your car. A good example is Noico Sound Deadening.

They come with automotive self-adhesive insulation. The materials are lightweight, ensuring efficiency and maximum sound insulation.

Installation of the Dynamat mats is quite easy; what you do is remove the floor mat then apply the sound dampening mat on the floor.

In addition, ensure that all insulation materials on the car body are functioning well and if not consider replacing them.

2. How to Reduce Road Noise in Car?

There are three ways you can address road noise in your car. Replacing your tires with softer rubber tires will help reduce road noise. When choosing, go for the tires with a higher profile instead of those with a lower profile for better results.

After changing the tires, you will notice a big difference, and your car cabin will be quieter than before. This helps reduce the road noise in your car.

As in the case of wind noise, adding a layer of Dynamat to the floor, doors, and bonnet’s underside will greatly minimize road noise.

You can also opt for a thicker layer of rubberized underbody coating to eliminate road noise. Ensure that you get the best coat from 3M or a trusted dealer as most of the underbody coating are scams.

3. Inspect your Car Engine

Some of the noise you hear while inside your car may be coming from the engine. It is normal for an engine to produce a low sound when the car starts, but some may produce unusual noise that can be annoying.

The reason for the unpleasant sounds may be old and dirty oil in the engine or use of engine oil that does not suit your car. Old and dirty oil does not lubricate well compared to fresh oil, which makes the engine to be noisy.

When the moving parts in the engine are not lubricated and come into contact, they produce some sounds.

Ensure your car is using the right oil. Unsuitable oil that does not suit your car and is less or heavier than what car needs. Most engines get quieter when they use synthetic oil than when they use mineral oil.

If the oil is okay, check whether the engine parts are worn out since they tend to produce noise. If they are worn out, consider taking your car to an experienced mechanic to replace the worn-out parts.

4. Inspect the Exhaust System

Most cars are designed with stock exhausts that do not make noise. If your car is using a free flow muffler, it will produce more sound compared to the stock exhaust.

The exhaust system over time rust and may develop small holes, making them noisier. Repairing or replacing such exhausts will bring a big difference in the noise levels in your car.

5. Check your Car’s Suspension Parts

Car’s suspension includes ball joints, suspension –link rods, shocker bolts, and steering ends. These parts can be the primary source of noise in your car. They need to be re-torqued after some time.

The bearings should be greased often to avoid friction, which later leads to wearing out, and finally, they start producing some noise.  If you can do the work yourself, then consider taking your car to a mechanic to attend to the suspension parts.

6.  Use Soundproof Sprays

The soundproof spray is a liquid soundproofing material. They mainly used in parts you cannot reach in your car, for instance under the car. They are cheaper and easy to use and work effectively.

The sprays are heat resistant and should be applied in multiple layers for better results. They can be used to block tiny holes in your car, which may be an entrance of noise into your car.

7. Regular Car Maintenance

Like any other vehicle, a car needs regular maintenance. If your car does not get regular servicing, then it is likely to produce noise. All the moving parts need to be lubricated from time to time.

Inspect the exterior car body to check if there are any damages, especially after an accident. Take your car to a professional mechanic frequently to check whether there is something that is not working properly.

Final Thoughts on How to make your car Quieter Inside

A lot of budget cars have poorly designed parts that cause rattles. The biggest culprits are parcel trays as well as interior trims and dashboard fitments.

Joints also need to be lubricated regularly to eliminate squeaking and rattling.

Above are different ways on how to make your car quieter inside. The key is to ensure that all these ideas work simultaneously.
