Hearing Aid Glossary Flashcards
What is Wind Guard ?
Detects wind noise, and adaptively reduces it.
The hearing aid user has a very natural sounding experience, with soft wind noise in the background and preserved audibility for other sounds in the environment
What is Noise Tracker II ?
Reduces unwanted background noise without affecting the quality of speech.
The stronger the setting the more the background noise will be reduced. Improves comfort in noisy listening situations without compromising speech understanding.
What is Impulse Noise Reduction ?
Reduces amplification for sudden, brief noises.
Improves listening comfort and sound quality for impulse sounds like clanking silverware or jangling keys
What is the Synchronised Acceptance Manager ?
Gradually applies gain over a chosen period of time, to reach final target fittings.
The 2.4 GHz wireless connection ensures that the adaptation process is coordinated between the client’s two hearing instruments.
Allows the user to gradually and comfortably adjust to the new hearing instruments
What is Tinnitus Sound Generator ?
Built-in Tinnitus Sound Generator with Nature Sounds consists of either fully flexible modulated noise or the option of several, water-inspired Nature Sounds, to help manage a client’s tinnitus.
Helps break the ‘vicious cycle’ and win some relief from tinnitus by diverting attention away from tinnitus
What is the Environmental Classifier ?
Analyses the incoming sounds and classifies them into listening environments
Complex sound processing adapts to the listening environment and provides a comfortable hearing experience.
What is SoftSwitching ?
Smoothly switches the hearing aid between omni and directional mode depending on the sound environment.
This is available for Adaptive Directionality, Multiscope and Autoscope options and unlike the binaural strategies, is also applicable to monaural fittings.
Natural and unobtrusive way to ensure hearing aids are in the directional mode when needed.
What is Digital Feedback Suppression (DFS Ultra™) ?
Reduces feedback while preserving amplification without compromising sound quality.
User is not bothered by feedback or by sudden reduction of volume, which some other hearing aids do to prevent feedback.
What is Music Mode ?
Slows down feedback cancellation to ensure that tonal sounds are not adversely affected utilising the same processing method. Rich sound quality for music is preserved.
Extra comfort, better audibility and a distortion-free music experience.
What is Sound Shaper ?
Allows audibility improvement for high-frequency sounds by compressing them in a frequency zone where they can be heard.
Improves the audibility of speech cues that would otherwise have been lost, while maintaining the best sound quality possible.
What is Environmental Optimiser ?
Provides automatic adjustment of hearing instrument settings across 7 different listening environments.
Hearing aid users can enjoy optimal audibility and listening comfort, even when moving through rapidly changing sound environments.
What is Adaptive Directionality ?
Adaptive Directionality dynamically changes the directional pattern to reduce the loudest sounds from the rear.
This is preferable to Fixed Directionality for users often in environments with multiple, moving, or simultaneous noise sources.
Creates an effect of zooming in on the speakers directly in front of the listener, and zooming out when the listener is surrounded by many speakers, resulting in improved speech to noise ratio and thus better speech understanding
What is Natural Directionality II ?
Provides the listener with the benefits of both omnidirectional and directional modes simultaneously.
Employs an asymmetrical fitting strategy with one ear always in directional (the “focus” ear) and one ear always in omni (the “monitor” ear).
Allows users to stay aware of background noises, increases ease of listening. No need for manual or automatic switching between different directional programmes.
What is Binaural Directionality ?
Relies on Ear-to-Ear data exchange to select the optimal microphone mode on each ear so the strongest voice signal is clear without losing the ability to perceive the surroundings and other speakers.
Users are provided with the information they need to instinctively react and tune in to the sound they are interested in.
What is Binaural Directionality III ?
Improves the ability to stay aware of sounds to the sides and back; more than 30% of the time, the signal of interest is not directly in front of the hearing aid wearer.
Providing the brain with the right information from both ears lets clients effortlessly follow conversations and shift attention naturally to important sounds around them.
