ACETT and conventional hearing aids

The technologies use different approaches. Hearing aids amplify acoustic sound for users who can benefit from amplification, while ACETT provides an alternative tactile channel for awareness and communication.

Conventional hearing aids

  • Primarily amplify acoustic sound.
  • Benefit depends on the user's hearing profile and residual hearing.
  • Focus mainly on auditory listening support.

ACETT Ecosystem

  • Converts acoustic information into tactile feedback.
  • Does not depend on sound amplification as the primary interaction channel.
  • Adds communication, learning and environmental awareness through the app ecosystem.
