Innovative Testing and Certification Solutions for Acoustics

Care for Ear Health Away from Noise

With the development of science and technology and the expansion of urbanization, not only a large number of artificial sound sources such as earphone speakers have appeared, but also the noise in public areas has also increased significantly. Therefore, the sound insulation needs and hearing attenuation problems of modern people are more obvious. Based on years of experience in the field of testing and certification and a large number of tests on related products on the market, TÜV Rheinland has set strict standards for hearing health and noise reduction capabilities to help everyone maintain good hearing and stay away from noise.

We are a globally recognized provider of testing and certification services with many years of experience in traditional access and voluntary services. We are well versed in industry requirements and provide a solid foundation for acoustic products to enter the market.

At the same time, we not only inherit our fine traditions, but also carry forward our excellence in multiple dimensions. Through relevant certifications such as hearing care, high-performance noise reduction, and low-noise and interference-free, we will open up broader possibilities for you.

  • All sound source products

Extensive research shows that long-term, repeated exposure to noise and single exposure to extremely loud sounds can cause irreversible damage to the auditory system, resulting in hearing loss.

Based on our continuous accumulation of large amounts of research in the field of hearing health, we ensure that products that have passed the test and obtained the certification mark will not cause hearing loss to users beyond normal physiological attenuation.

  • TWS earbuds
  • Notebook
  • Tablet

Various noises in daily life, especially low-frequency noise caused by friction, collision, etc., have great damage to the experience of personal audio equipment and the efficiency of voice information communication.

Through professional acoustic laboratories and strict certification standards, we can guarantee that the products have good noise reduction effects and voice communication quality.

  • Household electrical appliances

Studies have shown that the noise generated when home appliances are running can have a negative impact on people's sleep and memory, accelerate hearing loss and cause emotional instability.

We combine the objective measurement in a professional anechoic room with the subjective evaluation of real environmental noise to ensure that the noise during product operation will not have too much impact on the daily life of users.
