Patent ID: 8879745

Claim:
A method of deriving individual gain compensation curves for hearing aid fitting, comprising: providing a hardware and software system that detects, measures and records head azimuth for sound direction affirmation by a patient; establishing thresholds-of-hearing levels of the patient comprising: providing a user interface coupled to the system for allowing user input during at least one hearing test; providing pulsing tones to the ears of the patient, with each frequency of the pulsing tones for each ear being individually swept with ever decreasing intensity; allowing the patient to use the user interface to indicate to the system when the pulsing tones are no longer heard; and recording the pulsing tone level for each ear of the patient when the patient uses the user interface to indicate to the system when the pulsing tones are no longer heard; providing a plurality of audio signals through a plurality of test sequences to the ears of the patient, wherein the plurality of test sequences comprise: establishing binaural balance for right and left ears of the patient comprising; measuring an equal-loudness level by providing a first tone with a first sound pressure level to one ear of the patient and a second tone with a second sound pressure level to the other ear of the patient and varying the first and second sound pressure levels according to azimuth head motion; and instructing the patient to turn their head until the first tone is perceived to be equal to or balanced with the second tone between both ears of the patient; and generating at least two data points for each ear corresponding to the measured equal-loudness level with each data point of the at least two data points taken at different SPLs.
