@Sglass,
I don't know why they do that. It does happen when something gets very close to them. Put your hand over it, and it will squeel like a stuck pig. Sometimes, you hair falling across your ear will do it. Telephone receivers too, but it's not the electronics in the phone. Just the nearness of the mass.

I use the GN Metric, with three programs. One is over amplification, and for me it is almost unusable.

That's like putting a microphone next to a speaker (in this case, the microphone is built next to the speaker), it's a form of feedback which is some kind of looping sound that escalates between the microphone [input] that picks up sound and sends it to the speaker [output] that sends back to the microphone that sends it back to the speaker, etc....

Yep, that's feedback. Newer models are better at limiting it.

If it happens a lot, your audiologist should be able to fix that by fine-tuning the programming. Make an appointment.

I had to laugh. A friend that had been bugging me about getting ears fixed went off on a tangent about how wonderful it would be for me to be able to hear the "Birds".

The morning after I get my ears I got up early (dawnish) put on my ears and went out on the back porch to listen to the birds. You wouldda thought a tyrannius rex with feathers had landed on my porch with a boom box singing the Lullaby of Broadway with Hitchcock waving them on.

Unfortunately ambient background noises are amplified and it comes to a matter of "damn if you do and damn if you don't".

@Sglass,
There are usually4 possible reasons for feedback (whistling). 1. The aid is loose in the ear and sound is leaking out creating a feedback loop. It is similar to getting to close to a microphone. 2. The sound is going into the ear canal towards the eardrum and it hits debris (wax) and bounces back and creates a feedback loop. 3. It could also be internal feedback. That is when the sound being jutted down and it is going all over the place. Usually this would be continuous whistling no matter what you did. That reason the aid would need professional repair. 4. In bte if the tubing is crimped or leaking it can sometimes feedback.

@Sglass,
Reasons to screeching of hearing aids:


Hearing aids are not properly adjusted due to which too much power pump into higher frequencies.

Having too much wax in ear canal

Earmold is too small.

Aid is not properly inserted into earmold.

If it is Behind the Ear hearing aid, might have cracked tube or earmold that lets the sound to leak out.
