Abstract:
1. A method comprising: presenting, by a sound card, a first stimulus signal at a first frequency and a second stimulus signal at a second frequency to a user, the first frequency and the second frequency in a human audible frequency range; receiving adjustments, from a user interface operated by the user, to the first stimulus signal and the second stimulus signal to adjust an intensity of the first stimulus signal and the second stimulus signal; determining, by a processor, a first hearing threshold and a second hearing threshold based on the adjustments to the first stimulus signal and the second stimulus signal; calculating, by the processor, the difference between the first hearing threshold and the second hearing threshold to yield a user threshold difference; asking questions to the user from a questionnaire; receiving questionnaire answers from the user; calculating, with the processor, a user predicted pure tone average based on received questionnaire answers; receiving, with the processor, a user age; receiving, with the processor, a user gender; creating, by the processor, a set of candidate audiograms, where each audiogram in the set of candidate audiograms has an associated threshold difference comprising the difference between the first hearing threshold and the second hearing threshold, an associated predicted pure tone average, an associated age, and an associated gender; comparing, with the processor, the user threshold difference, the user predicted pure tone average, the user age, and the user gender, to the associated threshold difference, the associated predicted pure tone average, the associated age, and the associated gender associated with one or more audiograms in the set of candidate audiograms; and selecting, with the processor, a correlated audiogram from the set of candidate audiograms whose associated threshold difference, associated predicted pure tone average, associated age, and associated gender are most closely correlated to the user threshold difference, the user predicted pure tone average, the user age, and the user gender.
