The audibility challenge

Children with severe-to-profound hearing loss need maximum audibility and speech understanding without the risk of over amplification. Sumo DM addresses this issue in three ways:

• It shapes the frequency response and MPO to maximize the child's residual hearing
• It maps the three crucial levels of sound (soft, speech and loud) precisely into the child's restricted dynamic range
• It provides the compression ratio and dynamics necessary to meet the child's requirements

Sumo DM uses highly flexible frequency shaping plus linear and non-linear amplification strategies to achieve the above-mentioned goals.
