Hearing Aid Functions
When using the hearing aid functions:
You can listen to sound that has been slowed down.
You can listen to sound that has been made clearer.
You can listen to the sound once again.
This system employs digital signal correction technology to make the speaker’s voice sound clearer so that you can hear it easily.
7 Slow Function
Even rapid speech delivered by a news announcer is slowed down.
To make rapid speech easier to understand, the main unit lowers the speed at the beginning of each sentence and gradually resumes the actual speed. Use of intervals between words (blank time) produces slower but natural sound without changing the total time of each sentence.
7 Clear Function
You can easily catch sound that has been made clearer.
Aging people have trouble hearing small voices and feel discomforted by loud voices. The main unit produces clearer sound by correcting voices to a level aging people can hear easily.
7 Repeat Function
Even if you miss a word or sentence, you can play back the sound once again.
By constantly storing the sound (10 seconds maximum) to memory, the main unit can repeat portions you missed, including telephone numbers and unfamiliar words/phrases.
