Sound quality features of hearing aids

Sound quality features of hearing aids provide and support hearing ability, awareness and access to sound and communication.

High fidelity sound

High fidelity sound enables hearing aids to:

  • detect very high or low frequency sounds

  • detect very loud or soft level sounds

  • tailor the sound quality to increase or enhance enjoyment of music.

Manufacturers may use the following terms:

  • music programs

  • extended frequency range

  • extended dynamic range.

Frequency shaping

Frequency shaping enhances the sound quality of a hearing aid by making sure it is as close to natural hearing as possible.

Manufacturers may use the following terms:

  • binaural cue preservation

  • spatial cue preservation

  • streamed audio equalisation.

Frequency lowering

Frequency lowering uses technology to change the pitch of certain sounds so you can hear them more easily.

Manufacturers may use the following terms:

  • frequency lowering transposition
  • linear transposition
  • frequency compression.

Sound delivery

Features such as how sound is delivered to your ear are fundamental to providing safe and appropriate amplification. These physical parts can include:
