  1. Analog vs. Digital“’A Hearing Perspective” Andy Raguskus, CEO SONIC innovations, Inc.

  2. Range of Normal Hearing 120 Upper Comfort Level Lawnmower 100 Loudness (dB) 80 Vowels 60 40 Consonants 20 Threshold of hearing 0 250 500 1000 2000 4000 8000 Frequency (Hz)

  3. Typical Hearing Impairment 120 Upper Comfort Level Lawnmower 100 Loudness (dB) 80 Vowels Threshold of Hearing 60 40 Consonants 20 0 250 500 1000 2000 4000 8000 Frequency (Hz)

  4. Analog: 2 Channels 120 100 Loudness (dB) 80 60 40 20 0 250 500 1000 2000 4000 8000 Frequency (Hz)

  5. Digital: Graphic Equalizer 120 100 Loudness (dB) 80 60 40 20 0 250 500 1000 2000 4000 8000 Frequency (Hz)

  6. Digital Advantages • Understanding Speech in Noise • Graphic Equalizer • Compression • Temporal Cues • Background Noise Suppression • Reprogramming • Tiny Size Overcomes “Stigma” • Battery Life

  7. Summary • If the algorithms are robust, digital implementation is better than analog. • If the algorithms are not effective (majority of hearing aids in the world today), analog vs. digital doesn’t matter.
