Fitting of hearing devices
First Claim
1. A method for fitting a hearing device at least partially implanted under the skin for a recipient, the method comprising:
- obtaining hearing threshold levels for the recipient unaided by the hearing device;
obtaining hearing threshold levels indicative of a minimum signal for the hearing device that causes a hearing percept by the recipient based on the hearing percept caused by the hearing device due to recipient feedback;
calculating a transmission loss using the stored thresholds unaided by the device and the thresholds for the device, wherein the calculated transmission loss at least partially takes into account the effects of transmission due to the minimum signal for the hearing device travelling through tissue of 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 by applying gain that compensates for a percentage of the transmission loss that is greater than the percentage of the compensated hearing loss.

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 configured to be at least partially implanted under the skin, 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 stores 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 based on the hearing precept caused by the hearing device due to a response by the recipient, and to calculate a transmission loss using the stored thresholds unaided by the hearing device and the thresholds with the device, wherein the calculated transmission loss at least partially takes into account the effects of transmission due to the minimum signal for the hearing device travelling through tissue of the recipient;
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 gain applied compensates for a percentage of the transmission loss that is greater than the percentage of the compensated hearing loss. - View Dependent Claims (8, 9, 10, 11, 12, 20)
