An estimated 1.5 billion people suffering some form of hearing loss globally, an ageing population and a growing and substantial incidence of hearing loss among young people (most likely as a result of excessive noise exposure) are all fuelling the market for audiology devices. The challenges facing today’s manufacturers not only relate to sound quality and background noise rejection, but increasingly to personalisation and design for specific inner and outer ear conditions.

  • Hearing Aids– Advanced testing ensures high-performance and reliability in modern hearing aids.
  • Calibration of audiometers

Audio performance has become increasingly important to our everyday lives, both in entertainment but also, crucially in communication, where real-time global meetings between multiple people are held in often challenging environments with high background noise levels. Addressing these issues requires complex designs and accurate measurements to ensure customer satisfaction with the audio quality.

  • Entertainment Systems – Optimize acoustic performance in home theaters, surround sound, and gaming consoles.
  • Infotainment Systems – Fine-tune vehicle audio systems for music, conversation, and connectivity.
  • XR Glasses – Ensure audio-visual synchronization in VR, AR, and extended reality devices. 
  • Alarm & PA Systems – Improve voice clarity and reliability for safety alerts and public announcements.
  • Soundbar Testing
  • Headphone Testing
