So on Twitter, I try every month to participate in #HearingLossHour. Like it implies, it’s an hour-long Twitter chat with some question prompts—mostly based in the UK but I’m up early with the baby anyways so I like to think I provide the American perspective.

Anyways, September’s topic was about single-sided hearing loss, and that was a broad term, to encompass the fact that some people only have one “good ear.” For me, I can’t hear anything in my right (well, maybe I once faintly heard a fighter jet flying over) and wear a BTE aid in my “good ear.”

Amazingly, during the course of the chat, I learned something new that a LOT of other people know about, which goes to show that even though I do my best to stay on top of technology, there’s usually gaps in your niche knowledge, which is why things like Twitter conversations are so great. I learned that CROS (which stands for Contralateral Routing Of Signals) is like a hearing aid supplement for your “bad side,” carrying the audio picked up in a BTE receiver and throwing it into your main workhorse aid that you wear. Here’s the image from Phonak’s brochure to show what I mean:


What does that mean for me? It means I could wear it and have a MUCH easier time when I’m the driver in a car, because the passenger is on my bad ear. It’s hard to glance over to try and hear/lipread for a second, and maintain safe focus on the road, especially on the Beltway in DC… It means I wouldn’t have to try and arrange myself so specifically at every table in a group setting.

Phonak (who sponsors the monthly chat) has a CROS aid option that you can look into here. Starkey also has the Muse CROS, which you can look into here.

So I JUST got a new hearing aid fully covered by insurance in February, so it’ll be a few years before I can take advantage again and try to get a CROS system, because it seems like Oticon doesn’t manufacture CROS aids. Why did my audiologist not suggest it? I have no idea and fully intend to ask next time I go in. I do think it’d be weird to wear an aid of sorts on my right side again, as I haven’t done that since early childhood.

Do you use a CROS and love it?
