Right Phonak aid does not work. Three weeks ago it was the Left aid. No sound at all. I believe this has happened since I've updated my iMac to Tahoe. I suspect there is something going on with Apple or my network. Can Apple devices or my network cause interference? If so how can I find out and solve the problem?

Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?
Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue:
• If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.
• If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.
• To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.

NB>> Bluetooth uses the same frequencies as 2.4GHz Wi-Fi, but does frequency-hopping.

Thanks for your information, Grant.
When I went to the audiologist, she said this receiver, too, went bad. This is the second/or third receiver that I've had problems with lately. (The receiver in a rechargeable aid is the wire going from the aid sitting behind the ear to the plastic dome that is inserted in the ear).
Sometimes, it's the most basic things that need looking at - like a defective part.
Thanks for reporting back on your findings!
That really helps "the next guy" who may find your posting by searching.

As an aside, I personally hate the terminology of calling the part in your ear a "Receiver". Perhaps the Developers called it that from having the sound-generator 'down the ear-wire' instead of right there inside the body of the Hearing Aid.
To me, the part I plug into my ear seems like it should be called the SPEAKER, just like the Speakers in a home Hi-Fi Sound System. Tuner/Microphone(s)--Amplifier--Speakers
