Reduce noise

Identify and minimize the resonant frequencies that cause disruptive road noise. Optimize tread patterns for design that produces lowest noise.

tires durability

Increase durability

Pinpoint and mitigate excessive vibrations that can lead to premature wear and tear.

Improved performance

Refine the tire’s structural design and materials to improve grip, handling, and overall ride comfort, without compromising on the acoustic performance.

With electric cars producing less engine noise, tire noise becomes a more noticeable disturbance.

In EU tire labels even include rolling noise measurements ensuring the buyer can make conscious and well-thought decisions when purchasing.

Sorama’s CAM64 and CAM1K acoustic cameras offer an innovative solution for tire manufacturers, providing precise measurements and visualizations of tire vibrations. 

Our advanced acoustic imaging technology helps developers to design tires that deliver quieter, smoother, and longer-lasting performance, meeting the evolving needs of modern vehicles.

Impact of tire vibrations

Tire vibrations play a crucial role in driving comfort and safety. In traditional combustion vehicles, engine noise often masks the sounds created by tires. However, in electric vehicles, tire noise becomes more noticeable and can significantly impact the driving experience.

Mid- and high- frequency vibrations contribute to increased road noise, while lower-frequency vibrations affect grip, handling, and even wear. Understanding these vibrations is essential for manufacturers aiming to produce tires that offer both comfort and safety.

Quieter tires with acoustic camera

Sorama’s CAM64 and CAM1K acoustic cameras provide an easy, non-intrusive way to analyze tire vibrations.

Using sound recordings to create visual representations, our technology shows how tires move and vibrate, helping engineers understand both the shape and frequency of these vibrations. This real-time data is essential for designing quieter tires, especially for electric vehicles.

Benefits for tire manufacturers ​

1. Non-contact measurement: Our acoustic cameras create temporary and spatially high-resolution visualizations of tire dynamics without physically touching the tire, preserving its integrity throughout the testing process. 

2. Accurate visualization: Sorama’s technology precisely pinpoints the exact location and intensity of vibrations, providing detailed data for optimizing tire design. 

3. Comprehensive surface measurement: The CAM1K can capture data from the entire tire surface in a single measurement, enabling efficient analysis of large areas at once.

4. Real-time analysis: The CAM64 and CAM1K allow manufacturers to monitor and measure tire vibrations during real-world simulations, identifying noise issues and performance flaws early in the design process. 

5. Detailed air pressure and particle velocity mapping: Our cameras reveal how sound and vibrations travel within the tire, including how air pressure and particle velocity fluctuate in the time-domainThis near-field measurement provides crucial insights into the tire dynamics, which allows for designing quieter, more efficient tires. 

Testing for quieter tires

To meet the demands of both traditional and electric vehicles, tires are tested under various conditions, including static (unloaded) and dynamic (rolling) scenarios. Sorama’s acoustic cameras are key to capturing the complete sound and vibration profile of a tire in these settings. 

Static testing

The tire is suspended and subjected to controlled vibrations, allowing manufacturers to analyze how the tire behaves without load.

Dynamic testing

Rolling tests simulate real driving conditions by applying loads to the tire. The CAM64 and CAM1K cameras capture how the tire responds to these forces, enabling manufacturers to address noise issues and improve its performance.

The future tire testing with acoustic camera

As electric vehicles become more prevalent, the need for quieter tires will only grow. Sorama’s CAM64 and CAM1K acoustic cameras are helping tire manufacturers adapt to these changes by providing the precise data necessary for silent tire design. 

Integrating advanced acoustic imaging technology into testing and development processes allows manufacturers to produce high-performance tires that not only reduce noise but also offer superior handling and durability.

Improved driving experience

Sorama’s acoustic cameras provide tire manufacturers with the insights needed to optimize tire design. By visualizing vibrational modes and frequencies, our technology helps manufacturers to reduce noise, improve performance and increase durability.

With the near field acoustic holography Sorama’s cameras visualize vibration patterns in real-time, allowing tire manufacturers to make continuous improvements to tire designs, resulting in quieter, more efficient tires that improve the overall driving experience.

Tire manufacturing

Sorama’s CAMiV64 acoustic camera can further improve tire manufacturing by addressing compressed air leaks within the facility.

Compressed air leaks can significantly impact manufacturing efficiency and safety. They often result from worn-out seals, damaged pipes, or valves, causing increased energy consumption, decreased productivity, and potential safety hazards. 

 

Compressed air leaks: 

  • Reduced efficiency: Leaks cause machines to work harder, leading to increased energy use and decreased productivity. 

 

  • Increased costs: Higher energy bills result from inefficient air use. 

 

  • Quality issues: Leaks can lead to defects and potential recalls.

Traditional vs. acoustic detection methods

Traditional methods like sniffers and leak sprays have limitations, such as being time-consuming or less effective in noisy environments. Sorama’s acoustic imaging cameras offer a more reliable solution by detecting the sound of escaping air and converting it into visual images. 

By integrating Sorama’s acoustic technology, tire manufacturers can optimize their production processes, ensuring efficiency, safety, and high-quality products. 

The advantages include: 

  • Quick and accurate detection: Rapidly identifies leaks, reducing detection time. 
  • Non-invasive: Does not require physical contact with equipment. 
  • Easy to use: Minimal training needed for effective operation. 
  • Real-time data: Provides immediate insights for quick fixes.
