When portions of a signal are masked in noisy environments, perceptual restoration can be accomplished through auditory induction (AI). There are 2 classes of AI: (a) temporal induction (TI), which restores contextually appropriate segments of a signal masked at both ears by transient noises; and (b) contralateral induction (CI), which restores a signal masked at one ear when it is heard at the other. TI can prevent fragmentation of steady sounds and can permit comprehension of speech that would otherwise be unintelligible, while CI can prevent mislocalization of a sound source to the side of the unmasked ear. Both classes of AI are subtractive processes requiring that the neural units corresponding to the perceptually restored sound be among those stimulated by the louder interrupting sound. The rules governing AI provide information concerning general principles underlying perceptual organization in hearing.
