Selectable Digital Tone Setting
Personalize your amplifier to fit your individual hearing abilities by choosing from four digital tone settings. Each setting allows you to boost and enhance the specific speech frequencies you can't hear well, making difficult-to-hear words fully intelligible.
4 Tone Settings:
- Amplifies low frequencies making lower pitched sounds easier to hear. This setting is for people with low frequency hearing loss.
- Amplifies all sound frequencies equally making every word full volume and natural sounding. This is the standard setting.
- Boosts middle to high frequencies making each word more intelligible. This is for people with mild high frequency hearing loss.
- Amplifies high frequencies making high pitched sounds more distinguishable and easier to understand. This is for people with severe hearing loss and difficulty hearing high pitch sounds.
