I have been musing on which is better bilateral or bimodal.
At present I am bimodal, I have the MedEl implant in my right ear and a hearing aid in the left ear. In theory the hearing aid helps the implant with more rounded sound and especially with the lower frequencies that implants are not so good at. Now I have residual hearing in my implanted ear so I hear the low noises the old fashioned way using my ear drum, ossicles and cochlea. The left ear hears almost everything through the hearing aid apart from a tiny amount of sound that gets through the vent on the hearing aid mould. I really don’t like the quality of sound that I get on my hearing aids. The low frequencies are painful and reverberate on my ear drum and what happens is that I turn the volume right down to try to get rid of this noise. I’ve tried my Siemens Centra SP aid and my older Phonak Savia 311 and both have disadvantages and both have the same problem with the low frequencies. I think what I need to do is find a good hearing aid audiologist who can maybe adjust them a little I have had the Siemens tweaked to take down the high frequency sounds which did make it more comfortable. I did wonder about wearing the hearing aid and the implant in the same ear but I only have one pinna to hang the thing behind so that’s a little awkward.
Now, bilateral, an implant in each side. What disadvantages are there to being bilateral? I suspect that when a hearing aid doesn’t really five you any more advantages then the bilateral route is best. Not that I currently have that choice but maybe one day.
Any thoughts? experiences?
