Technologies adapted for hearing-​impaired children

August 12, 2016
Sound processing is essential to developing communication skills. Hearing loss affects children’s capacity to listen, talk, and read.

These abilities allow us to have conversations, express our needs and wishes, and create connections with people. While hearing loss occurs in the ears, the effects occur in the brain. The brain interprets sound and must be stimulated for its development. BrainHearing™ technologies allow constant signal processing to maximize your child’s language and speech development.

Instantaneous protection

BrainHearing™ technologies include Speech Guard E, an amplitude strategy using traditional wide dynamic range compression (WDRC) with linear amplification. When the input signal level is constant and stable, Speech Guard E uses linear amplification to retain speech details. If there are sudden changes in sound volume, Speech Guard E uses WDRC compression to instantaneously protect against excessive loudness and quickly improve low sound gain.

Children and noisy environments

K. Angelo and T. Behrens (2014) evaluated the impact of Speech Guard E’s double compression on speech comprehension in noisy environments for school-aged children (8 to 15 years old). They conducted three behavioural speech recognition tests adapted to children (Hint-C) under three amplification conditions: linear amplification, WDRC compression, and Speech Guard E (WDRC and linear).

The study’s main finding is that children demonstrate better word recognition with Speech Guard E double compression than with hearing aids using only linear or WDRC amplification. Above all, results show that specific amplitude compression characteristics in hearing aids have an influence on school-aged children, even when speech and noise are at moderate levels.
