Q: I have Autoimmune Inner Ear Disease (AEID). Would a Cochlear Implant be possible for me?

A: Every case of hearing loss responds to cochlear implantation differently. However patients with an auto-immune hearing loss generally do very well with cochlear implants. This is because their hearing loss is post lingual, the duration of the loss has been short and because the ganglion cell population in the cochlea is well preserved. The patients at my clinics with auto immune hearing loss (AIED, Sweet’s disease, Cogan’s syndrome, lupus and others) have all had good outcomes.

Q: Sometimes my hearing aid whistles when I first put it on in the morning – is this normal?

A: It is normal for a hearing aid to whistle when it is held in your hand, or if you turn it on before putting it in your ear, or if you cover it with your hand while it’s in the ear. Once it is placed in your ear properly and at your preferred volume setting, it should not whistle. If it continues to whistle this could be caused by a variety of factors. Some things that can cause feedback (whistling) include excessive earwax build-up, the earmould not sitting in ear properly, split tubing and increasing the volume of the hearing aid - so check these first. If none of these factors apply, you may need to go back to your hearing specialist for further advice and possibly a new earmould or reshell.

Q: I am suddenly hearing a lot of static or crackling. It is quite scary and loud.

A: This kind of sound usually does not come from inside the processor or the program, but is caused by a physical mechanism. The only moving part of your external processor is the coil cable, which is handled every single day, at least twice, morning and night. The plastic sheeting of the cord, which holds delicate wires connecting the processor with the transmitting coil can suffer wear and over time can tear the wires sending sound intermittently, causing a sensation of static or crackling.

Q: I am told by a fellow implantee that he changes the Microphone Protection cover on his Nucleus/Freedom processor every month, is this necessary and why?

A: The first time I realised how important it is to keep the microphone protectors clean, happened when a recipient reported the following observation: "I think I'm going mad! When I walk towards my television the sound becomes softer, and when I walk away the sound becomes louder!". Well, a bit of detective work showed the microphone protector was the culprit.
