Improvements in electric and hybrid technology have made car engines quieter recently. The overall joy of the in-car experience has been negatively impacted by this, though, as tyre noise is now more audible. The onus is in the hands of the tyre makers, to return the seamless driving experience to the riders.
- Modern vehicles, especially Hybrid and EVs are quitter since they have no engines
- The noise of conventional tyres has become more audible
- Tyre and road interaction and aerodynamic effects are two processes that affect tyre noise generation.
The Role of Tyres in Noise Pollution
Both internally and externally, tyre noise significantly contributes to vehicle noise pollution. It is produced by intricate mechanics that involve elements like friction between the tyre and the road surface, which causes vibrations and the transmission of sound waves. Airflow around the tyre and other aerodynamic phenomena can contribute to noise production. For tyre noise to be effectively addressed and tyre noise reduction solutions to be developed, it is essential to comprehend these mechanisms.
Identifying how much tyre noise contributes to overall vehicle noise levels is important. The importance of tyre noise has become increasingly apparent due to improved roads, advances in electric and hybrid technologies, and quieter automotive engines. In reality, studies have shown that tyre noise can contribute significantly to the overall noise made by a vehicle when travelling at modest speeds.
- The interaction between the tyre and the road surface, which causes vibrations and the transmission of sound waves, is one of the complicated mechanisms that contribute to tyre noise.
- Tyre noise makes a major contribution to overall vehicle noise levels, especially in light of developments in electric and hybrid technologies that have quietened automobile engines and increased tyre noise’s audibility.
- The tread pattern of a tyre plays a crucial role in noise generation as it determines how the tyre interacts with the road surface. Large, open blocks and aggressive designs in tread patterns tend to produce more noise than smaller, tightly packed blocks or patterns that are designed to reduce noise.
- Tyre noise is also influenced by the tyre compound, which specifies the exact materials used in tyre production. Harder compounds tend to produce less noise but may slightly reduce traction, whereas softer compounds often offer better grip but can increase tyre noise.
Advancements In Tyre Noise-Reducing Technology
To address the problem of tyre noise and improve the overall driving experience, tyre manufacturers have made breakthroughs in noise-reducing tyre technology in recent years. These improvements include the creation of innovative tread designs, the use of cutting-edge tyre compounds, and the incorporation of noise-cancelling materials in tyre manufacturing.
One noteworthy strategy used by tyre manufacturers is the creation of tread patterns with a focus on lowering noise emissions. Companies can reduce tyre rotation noise by designing tread patterns in a way that cancels out air compression vibrations. Noise emissions are significantly reduced by the placement of special grooves and blocks that are intended to jumble sound waves produced by air compression. An excellent example of this is Bridgestone, which has been using this technology in several of its tyres to produce quieter driving experiences.
Similarly, with their Pirelli Noise Cancelling System (PNCS), Pirelli has taken noise reduction a step further. This cutting-edge method involves adding a strip of noise-cancelling polyurethane to the tyre’s inner lining. As a sponge, the polyurethane strip absorbs and muffles the noise produced inside the tyre’s huge, empty inner air chamber. The PNCS makes this chamber, which is notorious for adding to tyre noise, a main target for noise reduction. Pirelli tyres now offer a quieter ride and much lower noise emissions thanks to the incorporation of this technology.
Advancements in noise-reducing tyre technology enhance the driving experience by minimizing intrusive tyre noise, reducing driver fatigue, and increasing overall satisfaction. These innovations also contribute to environmental goals by reducing noise pollution and demonstrating a commitment to a quieter and more sustainable future on the roads.
Benefits Of Tyres In Reducing Noise Pollution And Enhancing Passenger Comfort
Even though OEMs may achieve low NVH levels and a more peaceful ride with substantial insulation on the car body, tyre noise still annoys passengers, especially at higher speeds. This is where tyres that cancel noise come into play. The noise levels originating from the tyres have significantly decreased thanks to ongoing innovation from tyre manufacturers worldwide.
Noise-reducing tyres offer a range of benefits that contribute to improved driving experiences and environmental considerations:
-
Less Fatigue
Quieter tyres significantly enhance the overall in-car experience by minimizing the transmission of noise and vibrations to the cabin. This reduction in unwanted sounds allows occupants to fully immerse themselves in music, conversations, and other audio experiences, creating a more enjoyable and serene atmosphere. The ensuing serene and relaxing interior atmosphere significantly enhances driving comfort, decreasing driver fatigue and raising overall comfort, resulting in a more leisurely and enjoyable ride for guests.
-
Innovative Low Noise Pollution Tyres
To provide quieter and more serene surroundings, noise-reduction tyres are essential for minimising noise pollution in urban areas. These tyres reduce overall noise levels for passengers by reducing tyre noise, particularly at faster speeds. Innovative solutions, such as Goodyear’s SoundComfort Technology with its polyurethane foam component, efficiently reduce tyre cavity resonance, resulting in considerable reductions in peak tyre noise and vehicle interior noise and promoting a more peaceful soundscape for all.
-
Enhanced Tyre Performance
The maintenance of essential tyre performance characteristics while utilising noise reduction technologies is highly valued by manufacturers. By doing this, it is made sure that improvements in noise reduction won’t negatively impact crucial elements like rolling resistance, handling, braking, and tread wear. Tyres that prioritise these characteristics can efficiently minimise noise without compromising overall performance and safety. This method makes it possible to create tyres that are less noisy and still provide the best performance possible on the road.
-
Ongoing Research
An important factor in significantly lowering noise pollution is ongoing research and development in the tyre sector. Tyre manufacturers make investments in enhancing tyre compounds, improving tread patterns and investigating cutting-edge building materials. These initiatives seek to improve noise reduction capabilities without sacrificing tyre performance. Research & development activities assist provide increasingly quieter tyres that help reduce noise pollution and create more calm settings for communities by persistently pushing the limits of noise reduction technologies.
