Range of Normal Hearing Frequency (Hz) Loudness (dB) Threshold of hearing Upper Comfort Level Lawnmower Vowels Consonants

Typical Hearing Impairment Frequency (Hz) Loudness (dB) Threshold of Hearing Upper Comfort Level Lawnmower Vowels Consonants

Analog: 2 Channels Frequency (Hz) Loudness (dB)

Digital: Graphic Equalizer Frequency (Hz) Loudness (dB)

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

SummarySummary If the algorithms are robust, digital implementation is better than analog. 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.
