My first pair of aids (back in the '90s) used to buzz like a vibration when my Honda Civic car radio was on. But I think that was a mechanical issue with my aids that was later fixed. My 2nd pair of aids would go NUTS when in the room with any motion detector - seriously! There was such a detector in the ladies room at my work, and the dang aids would make a noise like: “CHA-CHA-CHA! CHA-CHA-CHA!” non-stop till I finished my business and got hella outta there. My aud-guy way back then even got on the phone with the company (may have been Starkey?) and asked if they’d encountered this? The aids would also go nuts at a couple coffee shops that had motion detectors near the cash register. I kid you not.
My current Oticon Opn aids just “blanch” at the microwave BEEPS (when the cycle is done and micro goes “BEEP! BEEP! BEEP!”) By that I mean, they seem to dampen down like a cringe - just a split second. I’m guessing that is the noise cancellation doing its thing.
So my question would be: at what point in the microwave cycle are your aids affected with interference? During the heating, or at the end of the cycle?
