Honda’s Innovative Noise-Cancelling Technology for Quieter Car Rides

Electric vehicles have highlighted that car tires are a significant source of unwanted cabin noise. Honda has devised a clever solution – hidden resonators that function similarly to noise-canceling headphones to eliminate tire noise.
Tires, made of rubber and filled with air, generate sound at specific frequencies when they make contact with the road, akin to a basketball hitting the ground. Honda’s engineers have identified these frequencies and developed passive resonators that are installed on the wheel rim inside the tire, effectively neutralizing the unwanted noise by addressing the air movement within the tire.
In the 2024 Corvette E-Ray, you can experience this technology on the track. Tires are essentially hollow rubber chambers filled with air, continuously interacting with the road surface. The noise produced within a tire, known as pipe resonance, travels through the suspension system and into the vehicle’s cabin, causing the audible tire noise passengers hear.
Honda’s innovative approach uses the principle of Helmholtz resonance—similar to the sound produced when blowing across an empty bottle—to design a resonator that encircles the wheel, generating a frequency to counteract the tire noise caused by air movement inside the tire.
Honda asserts that their noise-reducing wheels significantly diminish tire noise inside the cabin. The resonators, crafted from lightweight resin, are secured to the wheel with the help of centrifugal force and can endure forces up to 1,500 times that of gravity during high-speed driving. This design also minimizes unsprung weight, enhancing driving pleasure. First introduced in 2010, Honda’s practical noise-reducing resonator has since evolved into a second-generation version, which is half the weight of its predecessor.
