    Abstract: A field ready, unsupervised-use ready, method and apparatus for audio fittin g a hearing aid is described in a hand held configuration having paired comparison (hearing selections) stored in and derivable from a memory therei n. The paired comparisons are presented one at a time to a user and a preferred selection for each paired comparison is made by a select indicator after the user toggles back and forth between the selections for as many times necessa ry in determining their preferences. A genetic algorithm converges all the preferences upon a single solution. Crossover and mutation genetic algorithm operators operate on a linear range of indexes representative of parametric values of the pairs. A fully integrated hearing aid having all the above described features incorporated therein is also presented.
