“Decrease in sound…”

For a wee while I’ve been having some issues with my cochlear implant.

Batteries were barely making it to 2 days and the sound quality appeared to have dropped which made it harder to hear in busy settings.

Initally I thought maybe the change in brand of batteries given out was the issue, or that I had got a bad batch. My local audiology clinic informed me that they hasn’t had any other complaints and it must be my implant.

So I contacted the implant team at Manchester who sent me some parts to swap over on the outer bit of my processor. This still didn’t resolve the issue despite me tweaking and replacing various parts.

The sound was definitely getting worst and I must admit that there was a small niggle in the back of my mind that maybe there was something wrong with the internal processor as it’s been in my head for 10 years this August (amazing huh?!). The final straw for me earlier this week was struggling to hear a colleague sat across from me, as all I could think whilst she was speaking was, “She sound so muffled! There’s something not right here.” So I got in touch with the Implant Team at Manchester and arranged to go in to be seen.

So off I went taking the girl child with me on the train. Got a taxi from the station to the hospital. Was very glad that the girl child was with me as really struggled to hear what people said when they were giving us directions to the audiology department.

Was seen by a lovely member of the audiology team who took apart my processor, replaced various bits on it but it still sounded muffled. And then I decided to query the question that I had originally asked my local clinic. Was it possible that the change in brand of batteries would make a different? I then got out 2 packets of batteries that I had on me to show her. One was an old packet of batteries which I had forgotten about and found in my bag earlier and the other was a new packet which I had pop in there as per routine when going out. She took one look at the new packet and said “These aren’t cochlear implant batteries. These are hearing aids batteries.” The mystery was solved! 

She gave me the correct batteries to put in and honestly it was like coming out of water, I could hear clearly again and the sound was SO LOUD after these past few months of subdued hearing. 

The moral of the story? Trust your gut instincts and read the small print!!

To be fair to my local clinic, the boxes and the packets do look very similar. My Manchester Audiologist did say that those giving out the batteries (usually a receptionist) may not realise the differences in the power between hearing aid and cochlear implant batteries.

So now I have a letter to wave at them issued by Manchester, and I will definitely be checking all newly issued boxes in future when picking up batteries.
