Method and system for fitting hearing aids, for training individuals in hearing with hearing aids and/or for diagnostic hearing tests of individuals wearing hearing aids

摘要

A hearing aid is fitted to an individual and/or the individual is trained in hearing with the hearing aid. In a first step a stimulus signal is provided. In a second step, the stimulus is presented to the individual. In a third step, a response of the individual in regard to the stimulus is obtained. In a fourth step a hearing aid parameter is adjusted based on the response. In an alternative or additional fourth step, a further stimulus signal is selected based on the response. The second step of presenting the stimulus signal comprises the sub-steps of obtaining a first and second signal based on the stimulus signal. In a further sub-step, the first signal is processed and presented by the hearing aid. Simultaneously, in a further sub-step, the second signal is presented by a supplementary loudspeaker for improving the stimulus presentation in regard to direct sound.

主权项

1. A method comprising the steps of:
providing a stimulus audio signal by a stimulus signal provision means (42); obtaining a first audio signal and a second audio signal different from the first audio signal, which both are based on said stimulus audio signal; presenting said first audio signal, acoustically to an individual (1) by a receiver (22) of at least one hearing aid (2) worn by said individual and simultaneously presenting said second audio signal as direct sound acoustically to said individual (1) by at least one supplementary loudspeaker (31); receiving a response of said individual (1) in regard to said acoustic presentation of said first and second audio signal; and using said response in at least one of a process of fitting said at least one hearing aid to said individual; a process of training said individual in hearing with said at least one hearing aid, and a diagnostic hearing test of said individual wearing said at least one hearing aid; wherein said first audio signal and said second audio signal are different and wherein said first and/or said second audio signal is obtainable by filtering said stimulus signal, and wherein said first audio signal and said second audio signal are substantially complementary such that adding said first and second audio signal results substantially in said stimulus signal.
