A software speech strategy for running cochlear implants. The CIS speech strategy is digital and only fires one electrode at a time, but various electrodes are fired in rapid succession—833 times per second for the original software, and  5,156 times per second for the newer Hi-Res software.

A basic hearing aid that uses analog circuitry. This circuitry processes sound as a voltage rather than as bit as a digital hearing aid does. These aids tend to be relatively unsophisticated  and usually require the user to adjust the volume as needed.

Named for the shape of this kind of hearing loss on an audiogram. Both the high and low frequencies are normal or near-normal, but there is a broad dip in the mid-frequencies that looks like someone took a bite out of the top of the audiogram.
