Claim of US Patent No. 10,511,921

1. A method of pre-fitting a customizable sound processing device for a user, the method executed by a computing device and comprising:obtaining a hearing map representing the user's hearing, the hearing map being obtained by:
playing back acoustic signals to the user, the acoustic signals comprising at least one synthesized or recorded spoken word;
obtaining user input related to the user's perceptions of the acoustic signals, by providing a user interface through which the user may enter the word or words which the user heard;
determining an accuracy of the user input relative to the word or words actually played back and estimating, directly from the user input and without any intervening process of user specific testing, a percentage of information transmitted to the user; and
estimating, directly from the percentage of information transmitted to the user and without any intervening process of user-specific testing, hearing map parameters within specific frequency bands so as to derive the hearing map representing the user's hearing;
establishing a virtual signal processing path in the computing device which reflects a signal processing function of the customizable sound processing device;
updating parameters of the virtual signal processing path based on said hearing map; and
passing an audio signal through the virtual signal processing path and playing back the processed audio signal to the user.
