Fitting of hearing devices
First Claim
1. A method for fitting a hearing device for a recipient, the method comprising:
- obtaining threshold levels for the recipient unaided by the hearing device;
obtaining threshold levels indicative of a minimum signal for the hearing device that causes a hearing percept by the recipient;
calculating a transmission loss using the threshold for the recipient unaided by the device and the threshold for the hearing device that causes a hearing percept by the recipient;
generating one or more control settings using the calculated transmission loss; and
providing the control settings to the hearing device so that the hearing device applies a gain to sound received by the hearing device that separately compensates for the transmission loss and a hearing loss of the recipient,wherein the transmission loss is at least in part a result of losses at a coupling between the hearing device and the recipient, which coupling has at least a portion that is implanted in the recipient.

Abstract
The present invention relates to recipient fitting of a hearing device. An embodiment of the present invention determines the transmission loss for sound applied to the recipient by the hearing device. Separate gains are then determined for compensating for the determined transmission loss and the measured hearing loss of the recipient. For example, in an embodiment, the hearing device may compensate for transmission losses in a 1:1 manner (i.e., the transmission loss in 100% compensated for). The hearing device may apply a different gain to compensate for the hearing loss, such as a gain that is a fraction (e.g., 33-55%) of the measured hearing loss.

7. A fitting system for determining control settings for a hearing device, the fitting system comprising:
-
a device comprising; a processor; a data storage device; and an interface configured to connect to the hearing device; a user interface connected to the device to enable user interaction with the device; wherein the data storage device has stored therein thresholds for a recipient unaided by the hearing device; and wherein the processor is configured to; determine thresholds indicative of a minimum signal for the hearing device that causes a hearing percept by the recipient, and to calculate a transmission loss using the stored thresholds unaided by the hearing device and the thresholds with the device; to generate one or more control settings using the calculated transmission loss; and to provide the control settings to the hearing device via the interface so that the hearing device applies a gain to sound received by the hearing device that separately compensates for the transmission loss and a hearing loss of the recipient, wherein the transmission loss includes a transmission loss that is at least in part a result of losses at a coupling between the hearing device and the recipient, which coupling has at least a portion that is implanted in the recipient. - View Dependent Claims (8, 9, 24, 25)

10. A method for providing a hearing percept using a hearing device, comprising:
-
attaching the hearing device to a recipient; receiving a sound signal by the hearing device; applying a gain to the sound signal to obtain an adjusted signal, wherein the gain separately compensates for a transmission loss and a hearing loss; and applying the adjusted signal to the recipient using the hearing device to cause a hearing percept by the recipient, wherein the transmission loss is at least in part a result of losses at a coupling between the hearing device and the recipient, which coupling has at least a portion that is implanted in the recipient. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 27, 28)

18. A hearing prosthesis device;
- comprising;
a microphone configured to generate a signal based on a received sound signal; a signal processing system configured to amplify the signal from the microphone, wherein the signal processing system applies amplification that compensates for a transmission loss and a hearing loss of a recipient of the hearing device; and wherein the hearing prosthesis device is adapted to receive control settings for providing stimulation to the recipient to cause a hearing percept in the user based on the received sound signal such that the hearing percept is based on amplification of the signal from the microphone that compensates for the transmission loss and the hearing loss of a recipient of the hearing device, wherein the transmission loss includes a transmission loss that is at least in part a result of losses at a coupling between the hearing device and the recipient, which coupling has at least a portion that is implanted in the recipient. - View Dependent Claims (19, 20, 21)
