The Honda Accord has been around since the mid-70s and has been one of the best-selling sedans in the world since. The Accord is the perfect car for anyone that’s looking for an incredibly reliable and fuel-efficient car that can carry 4-5 passengers comfortably.

Over the years, the Honda Accord has not only grown in size but also in build quality. The latest (10th) generation of accord gets a completely different interior and exterior design that is far more aggressive, along with new engine options including a peppy 2.0L turbocharged 4 cylinder.

We see a lot of new Accord owners coming out of a slightly older model luxury sedan, like a Lexus or Infiniti, because the new Honda Accord provides so many features and amenities for a much lower cost. That being said, the biggest complaint we hear about almost all Accords is the road noise. It’s not unbearable, but when comparing it to something like an older model Lexus, owners tend to complain that there’s a noticeable difference in the cabin noise of the Accord.

That’s why we’ve created a complete guide to the best Honda Accord noise reduction treatments, no matter which generation you own.

Honda Accord Cabin Noise Reduction Treatment

While the Honda Accord is a nice, comfortable commuter car, it was designed to be an affordable car as well. This means that Honda had to use less sound-deadening materials than some higher-end brands, even their own luxury brand Acura. This can cause unwanted cabin noise. Luckily we’ve developed a kit to keep the cabin of your Accord quiet, just like a luxury car.

If you want the best Honda Accord sound deadening treatment, then check out our Mid Size Car Vehicle Soundproofing Package. This kit is designed to reduce car cabin noise caused by both structural and airborne sounds and will give you a noticeable difference in the cabin noise in your Accord. When installed completely, you can expect to reduce the interior noise of a Honda Accord by 10-15 dB when driving down the highway! The final result is it’s going to feel like you’re driving a luxury car that’s would’ve cost you twice as much as your Accord!

Inside the Mid Size Car Soundproofing Package, you'll find two of our most popular and highest rated products, Damplifier Pro and Luxury Liner Pro. This car soundproofing package provides the greatest amount of noise reduction, because it addresses both the structural and airborne noise inside an Accord.

What is Damplifier Pro?

Damplifier Pro has been the best performing sound deadening mat for almost 20 years. If you’re having rattling or vibration noises coming from your hood, doors, or anything else like this that’s made of metal. These noises are considered “structural”, because the sound energy is traveling through a physical object. Damplifier Pro is designed to silence structural noise by stopping any vibrating metal in your Accord. When you stop the vibrations, you reduce the amount of sound energy release into the cabin, which reduces the total noise level. You can apply Damplifier Pro to the trunk, floor, doors, hood, roof, and firewall to deaden these vibrations and get a noticeably quieter cabin.

We recommend 60% coverage to deaden structural vibrations within your Accord, but you can cover 100% of the metal if you want to max out the results. Because we max out our mat performance, you can choose to do less coverage than a lower end sound deadening treatment.

What is Luxury Liner Pro?

Luxury Liner Pro is our best-performing automotive sound barrier. Think of it as an extra wall that you install between the cabin and the sources of airborne noise in your Accord. We fuse mass loaded vinyl for cars to a decoupling foam layer to build a barrier that blocks Honda Accord engine noise, tire noise, and road noise (all types of airborne noise). You're going to want to get as close to 100% coverage as possible because the better your coverage, because airborne noise behaves a lot like water, leaking its way through any weak points.

Luxury Liner Pro should be installed as a 2nd layer on top of Damplifier Pro on the cabin side firewall, floor, and trunk. To extend the barrier up to the bottom of your windows, you can also install in the doors.

How to reduce Honda Accord Tire Noise

One of the biggest noticeable differences between the Honda Accord and its competitors is the road and tire noise. There’s nothing more annoying than cruising down the highway and hearing that constant whirring of the tires.

That’s why we developed Spectrum Liquid Deadener. This is the easiest way to achieve a tire noise and road noise reduction of 3-5 decibels in a Honda Accord, because it’s a completely external application. All you need to do to install Spectrum Liquid Deadener is apply 3mm of Spectrum into each wheel well (applied as 1mm layers – 3 total layers) directly to the metal. For 4 wheel wells, we recommend purchasing 2 gallons of Spectrum, applied with a spray gun, brush, or roller.
