We are pleased to present an insight into our NVH testing capability. In the following release you can learn what KFB can do around Squeak & Rattle (S&R) testing. These tests are crucial in ensuring that vehicles meet the highest standards of quality and customer satisfaction.

Squeak & Rattle refers to the noises and vibrations that can occur in a vehicle’s interior and exterior due to various factors, including material interactions, mechanical movements, and structural integrity. Such noises are often perceived as quality issues by customers, potentially affecting their overall experience and perception of the vehicle’s build quality.

Key Causes of Squeak & Rattle Include:

Material Interactions: Friction between different materials can cause squeaks.
Mechanical Movements: Loosely fitted parts or components can result in rattles.
Structural Integrity: Poor assembly or material fatigue can lead to unwanted noises.

Importance of Squeak & Rattle Testing:

Customer Satisfaction: Reducing S&R improves the perception of a vehicle’s quality.
Durability Assessment: Helps in identifying potential durability issues early on.
Regulatory Compliance: Ensures the vehicle meets stringent quality standards.

To ensure the highest level of testing accuracy and reliability, KFB has adhered to the following accreditations:

SAE J3168: A standardized method for evaluating and documenting squeaks and rattles in automotive components and systems.
ISO 17246: Specifies the acoustical testing requirements for road vehicles, ensuring a consistent testing environment and conditions.
VDA 230-206: Focuses on interior trim components, identifying potential squeak and rattle issues under various conditions.
GM NMD 9525P: General Motors’ proprietary test method for evaluating potential squeak and rattle issues.
Ford CETP 00.00-L-467: Ford’s internal standard for assessing S&R issues, ensuring compliance with their rigorous quality criteria.

Our commitment to quality is demonstrated through our adherence to the highest industry-leading standards. By performing Squeak & Rattle tests, we can assure automotive manufacturers that their products will meet the highest standards of quality, resulting in a superior user experience.

At the Acoustic Research and Innovation Center (ARIC), we are dedicated to maintaining the highest standards of quality and compliance, which form the cornerstone of the trust we build with our business partners. In line with our relentless pursuit of excellence and continuous improvement, ARIC is excited to announce significant advancements in our laboratory capabilities.

We extend our accreditation to include the measurement of the reverberation sound absorption coefficient, adhering to several key international standards:

PN-EN ISO 354: Reverberation sound absorption coefficient on large samples (10-15 m²).
PN-EN 1793-1: Sound absorption properties in the conditions of diffuse sound field of road noise barriers.
PN-EN 16272-2: Sound absorption under the influence of the diffuse acoustic field of railway noise barriers.
Standard 20189: Sound absorption by furniture and spatial elements.
PN-EN ISO 10140-2: Insulation of ceilings against air sounds, including evaluating impact sound insulation.
PN-EN ISO 10140-1 and PN-EN ISO 10140-3: Insulation of ceilings and increase in insulation against impact sounds.
Additionally, we are implementing advanced laboratory measurement methods for footstep noise on ceilings in accordance with PN-EN 16205, along with determining the RWS index in sones in accordance with ISO 532-1.

These advancements highlight our unwavering commitment to enhancing our capabilities and delivering superior acoustic solutions to our clients. As we continue to push the boundaries of acoustic research, ARIC remains at the forefront of innovation and quality in the industry.

As the number of electric cars continues to grow, so does the infrastructure supporting them, particularly high voltage AC/DC chargers. This increase in devices that emit constant, bothersome noise, often close to our living and working spaces, poses a challenge in terms of ecology and comfort of living. How can we manage it?

KFB Technologies would like to summarize its comprehensive capabilities and expertise to reduce noise output from electromobility infrastructure. Here’s what we offer:

#ARIC Laboratory Space and Expertise: We provide the necessary environment and knowledge to consult and support the design of silent solutions through specialized sound and vibration analyses, experiments, and simulations.

Testing: We conduct sound power level measurements of electromobility infrastructure according to a variety of standards, including ISO 3744, ISO 3741, ISO 3745, ISO 9614, and ISO/TS 7849.

As electromobility infrastructure expands, KFB Technologies is committed to innovating for a quieter, more pleasant environment. Interested in exploring opportunities for a better future? Let’s innovate together.

Nantes, France, August 2024 —KFB is taking part in in the 53rd International Congress and Exposition on Noise Control Engineering, Inter-Noise 2024, from August 25-29 in Nantes, France.

Hosted by the French Acoustical Society, Inter-Noise 2024 brings together global experts in noise control engineering under the theme, “”From Jules Verne’s World to Multi-disciplinary Approaches for Acoustics & Noise Control Engineering.”” This theme celebrates the intersection of science and imagination, inspired by Nantes-born author Jules Verne, and highlights the importance of multidisciplinary approaches in addressing the challenges of noise control.

We are excited to contribute to the event’s rich scientific dialogue, showcasing our innovative solutions in industrial acoustics. Our team, gathered here shortly before the beginning of the event, will engage in technical sessions and discussions on the future of noise control, focusing on emerging sound sources, urban soundscapes, and advanced acoustic data representation.
