The goal is to design and develop an auditory substitution device that through the use of a digital hearing aid and either vibro- or electro-tactile stimulation can substitute for regional frequency hearing loss.
Less power consumption – 1.2mW per 3 mm electrode
Potential for shock and burns (only @ v. large current)
Sensation quality varies
Limited dynamic range of sensation
Less variation in sensation
More power consumption - 138 mW per 4 mm electrode
Harder to attach
More complex constructionElectro- vs. Vibro-Tactile Stimulation
