title: Performance requirements for hearing aids.
abstract: The requirements for hearing aid frequency responses, SSPL characteristics, compression limiting, directional response, and internal noise are examined. On the basis of the assumptions made, aids would best serve the hearing impaired if they had flat very-low-frequency gains (and various mid- and high-frequency gains), SSPL responses adjustable in shape and level, directional responses, and internal noise levels below a recommended criterion level.
