You May Already Be Wearing Hearing Aids:
Perhaps they are old and no longer providing enough amplification
They don't fit well and are uncomfortable to wear for long periods
They whistle when you turn them up or when you're eating
They're too bulky and you'd like to look at the newer slim-tube or smaller in-the-canal hearing aids
It's probably time to have them repaired or replaced.
Sometimes they just need an adjustment or a new mould made but maybe they need replacing altogether.
