Trends in Amplification

Extensive personal experience with professional recording and audio signal processing technology has enabled the author to continue his music career after experiencing sudden sensorineural hearing loss. The iPhone™ is one such device that has been found useful for many music and general listening situations that would otherwise be intractable. Additional techniques and technologies are described that the author has found useful for specific situations, including music composition, rehearsal, and enjoyment...

To restore hearing sensation, cochlear implants deliver electrical pulses to the auditory nerve by relying on sophisticated signal processing algorithms that convert acoustic inputs to electrical stimuli. Although individuals fitted with cochlear implants perform well in quiet, in the presence of background noise, the speech intelligibility of cochlear implant listeners is more susceptible to background noise than that of normal hearing listeners. Traditionally, to increase performance in noise, single-microphone noise reduction strategies have been used...
