Hearing assistance device ear-to-ear communication using an intermediate device
Disclosed herein, among other things, are systems and methods for relaying wireless communication from ear-to-ear for hearing assistance devices using an intermediate device. One aspect of the present subject matter includes a method of using a first hearing assistance device in a first ear of a wearer to communicate with a second hearing assistance device in a second ear of the wearer using wireless communication, and determining whether quality of the communication between the devices has fallen below a programmable threshold such that communication can be improved by relaying the communication using an external intermediary device such as a smart phone. One method of determining the quality is to monitor a number of retransmissions that are used to maintain communication between the left and right devices.
1. A method, comprising: configuring a first hearing assistance device in a first ear of a wearer to communicate with a second hearing assistance device in a second ear of the wearer using wireless communication; sending a signal from the first hearing assistance device to the second hearing assistance device that can be relayed by an external wireless communication device; and if the signal has fallen below a programmable threshold, configuring the external wireless communication device to relay communication between the first and second devices, wherein the programmable threshold includes an interference threshold, a link margin threshold and a power capacity threshold and switching dynamically between direct communication and relay communication to improve link quality, latency and power consumption.
2. The method of claim 1 , wherein determining whether communication between the first device and the second device has fallen below a programmable threshold includes monitoring a number of retransmissions used to communicate between the first and second devices.
3. The method of claim 1 , wherein determining whether communication between the first device and the second device has fallen below a programmable threshold includes monitoring receive signal strength between the first and second devices.
4. A method of using an external wireless communication device, the method comprising: determining whether communication between a left hearing assistance device and a right hearing assistance device worn by a wearer has fallen below a programmable threshold; and if communication between the left device and the right device has fallen below the programmable threshold, configuring the external wireless communication device to relay communication between the first and second devices, wherein the programmable threshold includes an interference threshold, a link margin threshold and a power capacity threshold and switching dynamically between direct communication and relay communication to improve link quality, latency and power consumption.
5. The method of claim 4 , comprising eavesdropping on communication between the left hearing assistance device and the right hearing assistance device.
6. The method of claim 4 , wherein using the external wireless communication device to relay communication includes using a smart phone.
7. The method of claim 4 , wherein using the external wireless communication device to relay communication includes using a remote control.
8. The method of claim 4 , wherein using the external wireless communication device to relay communication includes using a tablet.
9. The method of claim 4 , wherein using the external wireless communication device to relay communication includes using a personal computer.
10. The method of claim 4 , wherein using the external wireless communication device to relay communication includes using Bluetooth communication.
11. The method of claim 4 , wherein using the external wireless communication device to relay communication includes using Wi-Fi communication.
12. A system for wireless communication, comprising: a first hearing assistance device configured to be worn in a first ear of a wearer; a second hearing assistance device configured to be worn in a second ear of a wearer; and a processor programmed to: determine whether communication between the first device and the second device has fallen below a programmable threshold; and if communication between the first device and the second device has fallen below the programmable threshold, configure an external wireless communication device to relay communication between the first and second devices, wherein the programmable threshold includes an interference threshold, a link margin threshold and a power capacity threshold and switching dynamically between direct communication and relay communication to improve link quality, latency and power consumption.
13. The system of claim 12 , wherein the communication relayed from the first device to the second device includes a 2.4 GHz communication.
14. The system of claim 12 , wherein the external wireless communication device includes a smart phone.
15. The system of claim 12 , wherein the external wireless communication device includes a remote control.
16. The system of claim 12 , wherein at least one of the first device and the second device includes a hearing aid.
