What Is An Acoustic Windshield?

An acoustic windshield is a type of vehicle windshield that is designed to reduce the amount of noise that enters the cabin of the vehicle.

The term “acoustic” refers to the fact that this type of windshield uses special materials and techniques to help absorb and deflect sound waves, making it more effective at reducing noise than a standard windshield.

An acoustic windshield generally work pretty much like a regular one.

It keeps you and everyone in the car safe from the debris that you may encounter while driving.

However, unlike the regular windshield, an acoustic one comes with a soundproofing insulation layer.

Sandwiched between the glass layers are the standard Polyvinyl Butyral (PVB) layer and an additional Acoustic PVB material.

It’s designed to interrupt the normal flow of acoustic vibration.

Once these vibrations hit the acoustic PVB layer, they are absorbed and converted into heat energy- similar concept to how green glue soundproofing compound works.

Even when you are driving through noisy areas, you can drive quietly and safely with this type of windshield.

Are All Windshields Acoustic Glass?

No, all windshields are not made using acoustic glass. The technology is recent, and most older car models have the traditional heavy-glass windscreen.

In the past all windshields were made of glass.

Since glass is a poor soundproofing material, different manufacturers tried to make it as thick as possible.

Later, windshields were advanced to the double-glazed variety. This one is made using two glass pieces with an air gap in between.

While the double-glazed windshield effectively reduces noise in the cabin, it is much heavier than the acoustic variety.

A few years later came the laminated acoustic windshield.

They were made of thin layers of glass bonded together using plastic.

Of these four varieties, the acoustic windshield stands out for its effectiveness in minimizing cabin noise and its light nature, and durability.

The laminated acoustic windshield comes a close second.

How To Tell If You Have Acoustic Windshield

If you have a car with an acoustic windshield, it will be noticeably quieter inside the cabin than one without. But how can you tell if your vehicle has this type of windshield? Here are a few ways to find out:

  • Check for a sticker or label. Many cars with acoustic windshields have a sticker or label on the inside of the windshield that indicates the noise reduction rating.
  • Look for special markings. Some manufacturers put special markings on the glass itself to indicate that it is an acoustic windshield.
  • Ask your dealer or mechanic. If you’re still not sure, ask your dealer or mechanic whether your car has an acoustic windshield. They should be able to tell you for sure.

Acoustic windshields can make a big difference in the noise level inside your car, so it’s worth finding out if yours has one.

Even if it doesn’t, there are other ways to reduce cabin noise, such as adding sound-deadening materials to the interior or replacing old, worn-out weatherstripping.

How Do You Know If You Have An Acoustic Windshield?

If yours is a modern car, it is likely that it comes with an acoustic windshield.

However, just to be sure, there are different ways to check if you are already enjoying this innovation.

First, this information may be written on the windshield along with other car details, such as the manufacturer and the logo.

Check for the word sound screen, acoustic, or A on the car information list of the windscreen.

Some manufacturers also add an ear image with a curved arrow passing by it. These words or images are the top or the bottom centre of your windscreen.

You can also check this information on your car manual.

If the car has an acoustic windshield, this information will be included somewhere under the windshield category.

However, you may see information on the standard and overall quality of your sound screen.

Benefits of an Acoustic Windshield

An acoustic windshield is a type of car window that helps to reduce the amount of noise that enters the cabin of a vehicle. There are many benefits to having an acoustic windshield, including:

  • Reduced noise levels: An acoustic windshield can help to reduce the overall noise level inside of a car, making for a more comfortable and relaxing ride.
  • Enhanced sound quality: When music is played through the car stereo, an acoustic windshield can help to improve the sound quality by reducing outside noise interference.
  • Improved fuel economy: A quieter cabin can also mean improved fuel economy as the engine does not have to work as hard to overcome exterior noise. This is especially beneficial for long-distance trips.
  • Increased safety: A quieter cabin can also mean increased safety as it is easier to hear things like emergency vehicles or oncoming traffic.
  • Enhanced privacy: Acoustic windshields can also help to provide a sense of privacy inside of a car, as outside noise is significantly reduced. This is ideal for those who want to make phone calls or have conversations without being overheard.

Is Acoustic Windshield Worth It?

The short answer is yes, the acoustic windshield is worth every penny, and the difference in cost with the traditional variety is not as much if you consider the durability.

The quiet you enjoy inside a car with an acoustic windscreen when on the road is simply divine.

Traffic noise can at times go beyond 75 dB, and if you spend hours on the road, this can be a lot to bear.

The noise of other vehicles, vibrations, and the air pressure as it pushes against the windshield can grow to uncomfortable levels, especially when driving at high speed.

Ideally, traffic noise should be about 25 dB.

Car manufacturers use different methods to ensure that the noise inside the vehicle remains within safe levels.                         

Traditionally, many car manufacturers used thicker glass to minimize the noise getting into the cabin through the windscreen.

However, the thick glass added to the weight of the vehicle, reducing its fuel efficiency.

Compared to these thicker windshields, the acoustic one minimizes sound transmission by over 60%.

The acoustic varieties are better at minimizing high-frequency noise, but generally, you will enjoy a 3-4 dB noise reduction.

If you are looking to soundproof your vehicle, an acoustic windshield will help shift the noise levels downwards.

However, you may want to combine this with other soundproofing solutions, such as damping mats.

Other benefits include:

  • Reduced UV transmission which protects the people in the vehicle and minimizes the fading on car interiors
  • Thinner windshields lead to lighter cars, reduced carbon emissions, and improved fuel efficiency.
  • Stronger windscreens that are durable and harder to break into in case of theft.
  • The acoustic layer prevents the glass from caving inwards in case of an accident, preventing glass shard injuries.

The Disadvantages of Acoustic Windshields

Well, acoustic windshields do not come cheap.

If you want to change your current windshield to an acoustic one, you will spend $400 upwards for the windshield alone.

When you consider the durability, you will see that the acoustic windshields are worth every penny.

It is also highly possible that the prices will go down as acoustic windshields become more common.

When you get the windshields installed, ensure that an expert does it. You do not want to get the acoustic layer damaged during installation.

You also have to care for your windshields. In case of a crack, have a professional seal to prevent damage to the acoustic layer.
