Helping you hear and enjoy a range of sounds
Features that provide a more natural sound or increase awareness and access to sound.
Examples of what this can help you with:
– Hear clearly with my hearing aids
– Hear front door bell or knock
– Hear traffic
– Enjoy music

High Fidelity Sound
This lets hearing aids deliver very high or low pitches, or very loud or soft sound levels. It can tailor the sound quality for better music enjoyment.
High Fidelity Sound in detail
Music Program is a specific hearing aid program which is intended to enhance enjoyment of music.
Intended Purpose:
Sound Quality
Audibility
Extended frequency range refers to the capability of a hearing aid to reproduce a wider frequency range than is usual for standard hearing aid performance. The extended range can be at low frequencies, high frequencies, or both. This is intended to provide enhanced enjoyment of music and may also improve speech perception and localisation cues.
Intended Purpose:
Sound Quality
Audibility
Speech Understanding
Localisation
Extended dynamic range refers to a hearing aid technology capable of processing sound with a wide range between the softest and loudest input/output. This can prevent distortion from loud sounds, as well as provide more natural reproduction of music.
Intended Purpose:
Sound Quality
Audibility
Speech Understanding

Frequency Shaping
Fits the sound to your hearing loss, so sounds are more natural.
Frequency Shaping in detail
Spatial Cue preservation aims to preserve or simulate the acoustic characteristics of the person’s head and outer ear which help to determine where a sound is coming from. This is done using either digital signal processing techniques or an additional microphone situated in the ear canal. These acoustic characteristics are often lost or distorted by the microphone placement in conventional hearing aids.
Intended Purpose:
Sound Quality
Localisation
Streamed audio equalisation improves sound quality by adjusting gain levels at specific frequencies. For example, compensating for bass leakage in open fittings and compensating for acoustic masking in noisy environments.
Intended Purpose:
Sound Quality
Audibility
| Look out for these words or technical terms sometimes used to describe them like: Binaural cue preservation, Spatial cue preservation, Streamed audio equalisation. |
Frequency Lowering
Changes the pitch of some sounds so that you can hear them more easily.
Frequency Lowering in detail
Frequency Lowering is a hearing aid technology that will shift, or lower, frequencies that are too high for the wearer to hear and shift them at a frequency range That is audible. This is done through a combination of methods, such as frequency compression, frequency composition, frequency transposition, and frequency translation.
Intended Purpose:
Speech Understanding
Audibility
| Look out for these words or technical terms sometimes used to describe them like: Frequency lowering transposition, Linear transposition, Frequency compression. |
Microphone and Receiver
The microphone picks up the sound from around you. The receiver is a tiny speaker that sends the sound from the hearing aid into your ears. Both can improve sound quality.
Microphone and Receiver in detail
Microphones capture sounds, and receivers deliver amplified sounds to the ears. Microphones in hearing aids are small devices that pick up sounds from the environment. They capture sounds and convert them into electrical signals that can be processed and amplified by the hearing aid. Some can even wirelessly connect the microphones between the hearing aids on each of your ears, further improving your hearing in background noise.
Receivers, also known as speakers or earpieces, in hearing aids are responsible for delivering the amplified sound directly into the user’s ears. They receive the processed electrical signals from the hearing aid’s circuitry and convert them back into audible sounds and deliver the amplified sound to the user’s ears. The receivers can be located either in or behind the ear, or directly in the ear canal. When Receiver In the Ear (RIE) or Receiver In the Canal (RIC) are typically placed within either an ear dome or the earmold. The choice and location of receiver depends on various factors, including the individual’s hearing loss, ear shape and size and personal preferences.
Intended Purpose:
Sound Quality
Audibility
Comfort

| Look out for these words or technical terms sometimes used to describe them like: Microphone or Receiver behind the ear, in the ear, in the canal. |
