This application claims priority of German application No. 10 2008 019 105.1 filed Apr. 16, 2008, which is incorporated by reference herein in its entirety
The invention relates to a method for setting a hearing aid and a hearing aid in which the hearing programs can be selected.
Modern hearing aids generally possess complex classification algorithms enabling automatic adaptation to environmental situations so as to ensure satisfactory hearing comfort and good speech intelligibility at all times. A method in this regard for adapting a hearing aid to a current acoustic environmental situation is disclosed in patent publication DE 603 07 576 T2. One of a plurality of hearing programs in the hearing aid is therein offered to the hearing aid wearer, while at the same time the current acoustic environmental situation is analyzed. Learning hearing aids, as described in patent publication US 2005 0129262, are also known.
In spite of all the aforesaid improvements, hearing aid wearers often wish for changes in the configuration of a hearing aid, also in the sequence of the stored hearing programs for example. Investigations and observations made by the applicant demonstrate that about half of all hearing aid wearers would like a change in the program sequence. At the present time, however, the sequence of the program positions can only be changed by the hearing aid acoustician or the manufacturer. This is perceived as inconvenient on the part of the hearing aid wearers.
It is the object of the invention to overcome these disadvantages and to disclose a method and an associated hearing aid which more effectively adapt the sequence of the program positions to the needs of a hearing aid wearer.
According to the invention the object addressed is achieved by means of the method recited 1 and the hearing aid recited in the independent claims.
According to the invention the method for setting a hearing aid in which hearing programs can be selected, the program positions of the hearing programs having a predefinable sequence, comprises the following steps:
Measuring time periods within which hearing programs are selected,
calculating a new sequence of the program positions with the aid of a learning algorithm, taking the measured time periods into account, and
modifying the sequence of the program positions after a predefinable time span in accordance with the calculated sequence. This offers the advantage that hearing aids adapt to new acoustic environments, and favorite programs are placed in the front section of the program positions in accordance with the hearing aid wearer's preference.
In a further embodiment variant the learning algorithm can weight the measured time periods, with the program position of a hearing program selected for a longer time being placed before the program position of a hearing program selected for a shorter time. As a result the usage time of a hearing program becomes a metric for the hearing aid wearer's preference.
In a development the learning algorithm can take into account at least one sound variable relating to an environmental situation and/or at least one desired setting value of the hearing aid. An advantageous aspect of this is the inclusion of additional characteristic variables.
Furthermore a selected hearing program can be signaled to a hearing aid wearer by means of a sound icon or a talking beep. Preferably the name identifying the selected hearing program can be displayed on a remote control of the hearing aid. By this means the hearing aid wearer quickly and easily recognizes the selected program.
In a further embodiment variant the hearing program in the first program position can be selected automatically when the hearing aid is switched on. This makes a hearing aid wearer's favorite program active immediately when the hearing aid is switched on.
Also disclosed according to the invention is a hearing aid in which hearing programs can be selected, the program positions of the hearing programs having a predefinable sequence. The hearing aid includes a measurement module by means of which it is possible to measure time periods within which hearing programs are selected, a computing module having a learning algorithm by means of which a new sequence of the program positions can be calculated taking the measured time periods into account, and a change module by means of which the sequence of the program positions can be modified after a predefinable time span in accordance with the calculated sequence.
In a further embodiment variant the computing module can weight the measured time periods in such a way that the program position of a hearing program selected for a longer time comes before the program position of a hearing program selected for a shorter time.
In a development each selected hearing program can be signaled to a user by means of a distinguishable sound icon or a different talking beep through a hearing aid receiver. By this means the program selection becomes clearly audible.
Advantageously, the name of the selected hearing program can be displayed on a display of a remote control.
Furthermore, the hearing program in the first program position, which can correspond to the favorite program of a hearing aid wearer, can be selected automatically when the hearing aid is switched on.
In a development the hearing aid can be preconfigured at the time of sale/dispatch in different hearing programs for different hearing losses. As a result the hearing aid does not have to be specially adjusted at the time of sale or, as the case may be, at the time of dispatch to the hearing capacity of the hearing aid wearer.
Further special features and advantages of the invention will become apparent from the following explanations relating to an exemplary embodiment and with reference to schematic drawings, in which:
A program selection button 10 for selecting hearing programs is connected to an input and output of the signal processing and transmission unit 8 and to an input of a time measurement module 2 via a program selection module 11 in which, inter alia, the sequence of the program positions is stored. An output of the time measurement module 2 is connected to an input of the signal processing and transmission unit 8. A remote control 12 is connected to an input/output of the signal processing and transmission unit 8 via a wireless interface.
When the hearing aid 1 is shipped or after it has been set by a hearing aid acoustician, the program positions of the hearing programs have a sequence corresponding to the expected usage behavior of a hearing aid wearer. In this case the most preferred hearing program is in the first position and the program that is expected to be least useful is placed last. However, the real needs of the hearing aid wearer are usually different from these preset default settings. Only when the hearing aid is in operation does the user realize that other hearing programs are more important and therefore need to be placed in a position further forward in the sequence so as to be more easily and quickly selectable.
The time measurement module 2 therefore measures the time periods within which individual hearing programs are selected. From these time periods a computing module 3 in the signal processing and transmission unit 8 calculates a new sequence of the program positions with the aid of a learning algorithm. After a definable time span this new sequence is transmitted to a change module 4 which thereupon modifies the sequence of the program positions in the program selection module 11 accordingly. The new sequence is then made available to the hearing aid user. The different programs are recognizable by means of distinguishable sound icons or talking beeps in the receiver.
Over a defined time span the hearing aid 1 therefore automatically learns which is the preferred hearing program of its hearing aid wearer from the measured individual usage time. For example, the first program position is occupied by the most frequently used hearing program, the second program position by the second most frequent, etc.
As a result a hearing aid user's favorite hearing programs are placed in the front section of the program positions. In addition the hearing aid can start already in the favorite program of a user, since hearing aids typically start in the first program.
