Claim:
1. A method for automatically generating a personalized equalization filter for listener, the method comprising: measuring a first hearing profile of the listener as a deviation of a first recorded response profile, obtained from a first equal loudness hearing test when the listener is listening through a personal listening device in a personal listening environment, from a first reference equal-loudness contour associated with a first given phon level; automatically generating a first personalized equalization filter based on the measured deviation of the first hearing profile such that application of the personalized equalization filter to an audio signal played through the personal listening device provides an equalized listening profile that recovers the equal-loudness contour for which the hearing profile was measured; applying the first personalized equalization filter to an audio signal played through the personal listening device; and automatically adapting the personalized equalization filter to a new phon level that differs from the phon level for which the listener's hearing profile was measured so that the personalized equalization filter automatically adapts to match an equal-loudness contour of the new phon level, wherein automatically adapting the personalized equalization filter to a new phon level that differs from the phon level for which the listener's hearing profile was measured comprises: wherein automatically adapting the personalized equalization filter based on the second recorded response profile and the second reference equal-loudness contour associated with the second given phon level comprises:
