This Occlusion Effect is very common and may indeed by a primary cause why hearing aids are rejected.
It has NOTHING to do with hearing aids being ‘new’ etc.
It is simply an effect caused by the ear canal being blocked by a lump of plastic.
The air gap between the hearing aid or earmould and the eardrum can trap low frequency sounds being transmitted through the skull from the jaw or from your own vocal cords.
This trapped sound can reach VERY high levels which can drown out the outside world when you eat or when you talk and is very disconcerting.
So if you have good hearing loss at 250H or 500Hz then you can’t really wear any sort of aid which totally blocks the ear canal.
This is why Open Fittings are now so popular: theses aids let the low frequency sounds roam free like a wildebeest, and only boost the mid and high frequencies.
If you can’t avoid a lump of plastic in your ear:
- Make sure it has a vent drilled through it.
- Consider asking for the aid gain for Low Frequency Louds to be reduced.
Your hearing aid supplier should know ALL about occulsion so you shouldn’t be sent away with your aids behaving like that.
