ANC Noise Cancellation: A Powerful Function

After the invention of ANC technology, noise-cancelling headphones have become mainstream. Whether on public transportation, in noisy fast-food restaurants, cafés, or airports, noise-cancelling headphones can people who need to focus on their work and want to block out external noises. However, can these headphones perform well in an actual noisy environment?

To achieve the best performance, other than carrying out tests during the product development stage, running simulations of real user scenarios in different environments is key. Different environmental factors are often unpredictable and uncontrollable. This is the reason why field testing is crucial to ANC headphone development.

Allion has invested in acoustic testing for years and our wireless acoustic testing consultant team discovered that environment simulation testing is one of the biggest hurdles for manufacturers. Other than being expensive, running such tests involves many different types of risks.

Potential Risks

Below are some potential risks that have been summarized by our wireless acoustic testing consultant team:

  • Interference from the environment
  • Occupied Bluetooth frequency
  • Uncontrollable ambient noise
  • Various noises from the environment affect the performance
  • Oversimplified acoustic testing, not considering the characteristics of the human anatomy

When the headphones are put to test in actual user scenarios such as bus stations, airports, offices, or public transportation environments, the factors that affect the results can become very complex.

Reproducing an Ambient Noise Field is Easier Than Ever

Based on the risks mentioned above, Allion can provide clients with environmental noise field testing for different scenarios and users. Our consultant team records actual noise conditions on-site and then builds the simulation of each sound field. With this type of reconstruction technology, we can help manufacturers simulate various environment scenarios to test and verify product performance.

With this technology, the services we can provide for ANC products include:

 Subjective assessment 

Professionally trained experts will conduct listening assessments.

  • Noise cancellation performance: Experts will evaluate the noise reduction performance of ANC headphones in various environments
  • Call quality: Experts will evaluate whether the noise reduction can provide a better voice quality in various environments.

 Objective assessment 

Conduct objective evaluations with test standards and measuring equipment.

  • Noise cancellation performance (Insertion Loss, ISO 4869-3)
  • Call quality: (POLQA, ITU-T P.863)

Allion’s wireless acoustic testing consultant team can provide the most realistic and comprehensive ANC headphone testing environments. With our sound field reconstruction technology, we are confident that we can help clients improve their products.
