1. A method for user fitting of a hearing aid, said method comprising:
performing an initial fitting of the hearing aid in an interactive session between a hearing aid user and a fitter to establish settings for the hearing aid,
for a predetermined period after said initial fitting, allowing the hearing aid user to adjust the settings of the hearing aid, monitoring the hearing aid user’s choice of at least some of the settings and storing said monitored choices in a log,
transmitting said log to the fitter for evaluation of preferred user settings,
evaluating said preferred user settings, and
if said evaluation reveals that the preferred user settings are acceptable, finalising the fitting of the hearing aid accordingly, or
if said evaluation reveals that the preferred user settings are not acceptable, performing an action selected among:
finalising the settings of the hearing aid in accordance with the initial fitting,
performing a new interactive session between the user and a fitter, and
monitoring for a new predetermined period, the user’s choice of at least some of the settings of the hearing aid and storing the results of the monitoring in a log.
2. The method according to claim 1, comprising the transmission of an appropriate code to the hearing aid, said code indicating whether
the settings of the hearing aid are to be finalised in accordance with the preferred user settings,
the settings of the hearing aid are to be finalised in accordance with the initial fitting,
a new interactive session between the user and the fitter is to be performed, or
the user’s choice of at least some of the settings of the hearing aid are to be monitored for a new predetermined period.
3. The method according to claim 2, wherein the hearing aid is a network enabled hearing aid and, wherein said code and said code are transmitted to the fitter via the data network.
4. The method according to claim 1, wherein the hearing aid is a network enabled hearing aid, and wherein the log is transmitted to the fitter for evaluation of the user’s choice of settings by means of a data network.
5. The method according to claim 4, wherein said data network comprises the internet.
6. The method according to claim 1, wherein said settings comprise the maximum gain in at least one frequency band.
7. The method according to claim 1, wherein said settings comprise the compression ratio in at least one frequency band.
8. The method according to claim 1, wherein said settings comprises the user’s choice of programme.
9. The method according to claim 8, wherein said finalising comprises removal of unused programmes.
10. The method according to claim 1, wherein said hearing aid is finalised according to the initial fitting, if said period expires without any log file having been sent to the fitter.
The claims below are in addition to those above.
