First Claim
1. A hearing aid system comprising:
- a programmable hearing aid having a housing adapted to be worn at an ear, said housing containing an input transducer and an output transducer with a signal path therebetween, signal processing means connected in said signal path for influencing a signal in said signal path dependent on a parameter set, and a parameter set memory accessible by said signal processor means for storing at least one parameter set for use by said signal processing means;
identifier means in said housing for identifying a current hearing situation defining an environment in which said programmable hearing aid is disposed;
matching means for allocating respective parameter sets in a plurality of parameter sets to different hearing situations, said matching means including a first memory for storing said plurality of parameter sets, input means for identifying a current hearing situation among a succession of hearing situations and for allowing a wearer of said hearing aid to select and allocate a parameter set, for said plurality of parameter sets, for each hearing situation each time it occurs, a second memory for storing respective allocations made by said user among said parameter sets and said hearing situations, and control and processing means for evaluating said allocations in said second memory for assigning a parameter set among said plurality of parameter sets to each hearing situation dependent on said allocations and for programming said parameter set memory with said parameter sets respectively allocated to said hearing situations, said parameter set memory then supplying to said hearing situations, said parameter set memory then supplying to said signal processing means, when a current hearing situation is identified by said identifier means, the parameter set allocated to the current hearing situation; and
said matching means comprising an external control module. including at least said input means, and an auxiliary module, said auxiliary module containing a remainder of said matching means not contained in said external control module, and means for wirelessly transmitting data at least from said external control module to said auxiliary module, said auxiliary module being temporarily mechanically connectable to said housing and adapted to be worn at an ear together with said housing during a matching procedure, consisting of a training phase and a hearing aid configuration phase, in which said respective parameter sets in said plurality of parameter sets are allocated to different hearing situations and being electrically connected to said signal processing means, and after said matching procedure said auxiliary module being removable from said housing.

Abstract
A hearing aid system with a hearing aid has a matching arrangement with a first memory for several parameter sets available for selection for each of several hearing situations, an input unit for selecting a current hearing situation and for selecting one of the several parameter sets available for this hearing situation, and a second memory for allocation data that identify the parameter sets selected for each hearing situation. For the determination of an optimal parameter set for each of several hearing situations, an optimal user-specific parameter set is allocated to each hearing situation as it arises during an optimization phase. After the optimization phase, the allocation data are evaluated for the determining an optimal parameter set for each hearing situation. This parameter set is then permanently programmed as the parameter set which will be called to set the transmission characteristics of the hearing aid whenever the hearing situation allocated thereto occurs.

13. A method for determining an optimal parameter set for controlling transmission characteristics of a programmable hearing, aid having a housing containing a signal processor, in each of a plurality of different hearing situations, comprising the steps of:
-
temporarily mechanically connecting an auxiliary module to said housing and temporarily electrically connecting said auxiliary module to said signal processor;
providing a remote control in a wireless communication with said auxiliary module;in a training phase, wearing said hearing aid and said auxiliary module by a user in said plurality of different hearing situations; in said training phase, making a plurality of different trial parameter sets from said auxiliary module available for selection by said user in each hearing situation each time a hearing situation each time a hearing situation occurs; in said training phase, for each hearing situation, said user selecting one of said trial parameter sets deemed optimal by said user and storing an allocation in said auxiliary module of said one of said trial parameter sets to the hearing situation for which it was deemed optimal; in a hearing aid configuration phase, evaluating all of the stored allocations of said trial parameter sets to the different hearing situations and remotely programming said hearing aid via said auxiliary module, using said remote control to assign one trial parameter set in said hearing aid to each hearing situation for controlling said transmission characteristics of said hearing aid when said hearing situations respectively occur; and removing said auxiliary module from said housing. - View Dependent Claims (14, 15)
