Hearing aids can only improve on the frequencies that you can hear. I can not hear alarms such as smoke alarms, alarm clocks or anything at a high'ish pitch, I have a vibrating pad under the sofa and bed to alert me if the smoke alarm goes off. This also affects speech as I can't hear certain frequencies when people talk. Doesn't matter how loud people talk, even at the IMAX cinema that is loud enough to make ears bleed I still can't understand what people are saying.
