Question for the group regarding interference and hearing aids. I’m a long time hearing aid user and I’m currently wearing Resound Linx3D 9 RIC hearing aids. I was standing outside yesterday and I suddenly started hearing a bunch of crackling in one of my hearing aids. It wasn’t continuous, more like it would crackle for 2-3 seconds, stop and then start again. I turned the hearing aids off/on multiple times and eventually it went away and hasn’t returned. My first thought was that the RIC was going bad but given everything is ok today, I’m thinking it may have been some kind of electrical interference. I wasn’t connected to my iPhone at the time so it definitely wasn’t Bluetooth interference between the phone and the hearing aids. I have noticed over the years that certain devices do cause interference/crackling sounds with hearing aids. A few examples include:
- The anti-theft sensors in the doorways of clothing stores that are designed to detect the security tags on clothing and other items. Walking past store entrances with these sensors sometimes causes weird noises in hearing aids.
- Ultrasonic measuring tapes that are used to measure room dimensions also cause funny crackling noises in hearing aids.
I wondering if there was a nearby thunderstorm and maybe the lightening was causing inference. My other thoughts was that they are rolling out and testing 5G mobile network services in Toronto and I’m hoping this new technology isn’t causing interference.
