Fitting device for hearing aid stores sound source for test subject's evaluation of each solution vector

摘要

The device includes an initial solution setting device (2a) for defining an initial set of solution vectors to be updated. A parameter writing device (2b) converts the solution vector into adjustment parameter values for the hearing aid and stores them in a hearing aid parameter memory (4). An evaluation value acquisition device (2c) obtains a test subject's evaluation value for each solution vector. An optimal solution estimation device (2d) estimates an optimal solution based on the value of each solution vector and the evaluation value for each solution vector. A sound source memory (1a) stores the sound source for the test subject's evaluation of each solution vector. A sound source presentation device (1d) presents the sound source to the hearing aid, the sound source being ambient noise.
