Create the Quietest Cars: Why Car Companies Are Making Their Cars Quieter

Quiet Cars

Do you know that a diesel truck that’s 50 feet away generates more than 90 decibels of noise? Any noise greater than 85 decibels can lead to permanent hear loss!

Loud cars are very irritating. Imagine you not being able to listen to your favorite music because your car is overwhelmingly loud. Car manufacturers are currently using innovative technology to make your SUV quieter.

So how do manufacturers make quieter cars?

Today, more car manufacturers are focused on creating the quietest cars. Why is that? Read through to understand why the demand for quiet cars is consistently on the rise.

How Car Exhaust Is Essential in Making the Quietest Cars

Car exhaust is what determines whether the car will be quiet or not. An overly noisy exhaust affects the silence inside the car. So, most manufacturers are now on the lookout on how they can do away with noisy exhausts.

However, some manufacturers opt for a shortcut which is not advisable. They often make the car soundproof. As a result, their deceive car owners that they are driving in a quiet environment yet it’s very noisy outside.

Such cars can bring you problem with governing authorities. Remember, while driving, your car shouldn’t affect how everyone is going about their daily activities. Avoid getting into trouble by getting yourself a car that has a quiet interior and a less noisy exhaust.

What Makes the Cars Noisy?

Cars are noisy due to two main reasons. The first reason is that their exhaust may be too old and thus needs replacement. Therefore, they don’t perform their emission work efficiently, thus causing excess noise.

Secondly, the problem might be the car itself. Certain cars are so powerful that they use a lot of energy to emit burnt gas. This is more common with most sports cars, especially when they’re in the turbo mode.

Fortunately, for these super cars, you can adjust your turbo sound levels. However, if your exhaust is too old, it needs quick replacement to avoid more problems. Besides, you can employ specific innovative techniques to make the exhaust less noisy.

So how do manufacturers fix this problem without compromising on the performance of the car? Here are some techniques that they use in quieting car exhaust.

Installing Sound Mufflers

A car muffler is the last part that precedes the exhaust pipe before the opening. The primary role of car mufflers is to ensure that the exhaust is quiet during emission of burnt gas. But improper installation will lead to noisy exhausts that even affect car performance.

How do you know that your muffler is not functioning correctly? Well, if you’re driving your car and you can hear the exhaust rumbling from the inside, it means that something needs immediate attention. It also means that those who are outside are negatively affected by the loud noise.

How do you fix this? The best solution is getting yourself a new muffler from a reputable manufacturer. The price of a new muffler installation varies depending on the type of the car.

Ensure that you only hire an expert to install the muffler. Otherwise, you’ll be doing zero work and thus lose a lot of money for the poor installation. Besides, this can also affect the overall performance of your car, leading to downtime losses that you should avoid at all cost.

Also, check the quality of the new muffler. Most car owners often make the mistake of merely extracting an old muffler from their old cars. As such, they end up damaging the car exhaust leading to more loud noises.

Making Heat-Resistant Exhaust Pipes

Sometimes, the noise is due to leaking exhaust pipes. You may think that it’s difficult to make holes on the exhaust pipes. But consistent emission of hot air from the exhaust pipe affects a car’s performance.

The only sure way of avoiding this is by making exhaust pipes out of heat-resistant metals. Many manufacturers often combine different metals to produce a metal that is more resistant to heat. It’s therefore very crucial to inspect your exhaust pipe to ensure that it’s made of durable metals.

Otherwise, it won’t serve you for a long time. Hot air makes the exhaust pipe to expand. During cold temperatures the exhaust pipes contract.

The contraction and expansion of the exhaust pipe cause it to stretch and pokes holes into its system. Therefore, weak metals are not suitable for the manufacturing of exhaust pipes because they compromise functionality, leading to poor performance.

Currently, many manufacturers have invested in research to discover new metal combinations that are suitable for car exhaust pipes. Notable innovations in this field are used to make the cars quieter than before. Besides, more vehicle manufacturing companies are committed to ensuring that the world is free from noise pollution.

Installing Silencers

Another common technique amongst most car manufacturers is the use of a silencer. How do they work to improve on soundproofing services?

The silencer narrows the path through which sound passes in the exhaust pipes. As a result, silencers reduce the overall impact of loud sounds in exhausts. In general, narrower sound paths result in quieter noises.

Muffler silencers have flexible prices. However, their installation is delicate, and a slight mistake can cost you a lot. You should only hire an expert to install the silencers professionally.

Moreover, there are numerous tutorials on how to make DIY silencers, but some are misleading. You should, therefore, only use silencers from reputable manufacturers.

More Tips

If your car exhaust is now quieter, but you can still hear unpleasant noise, you should soundproof your cabin. Use sound deadening mats on your car floor and roof. Also, ensure that any loose metal within the car is fixed correctly to reduce the noise within the cabin.

Everybody loves a quiet car, and you should always ensure that your car noise is within acceptable limits. Every fortnight, manufacturers enroll out new ideas to make the quietest cars. Check out our blog for more information on innovative trends in the automotive industry.
