I think I hear just fine, but my family doesn't. I can hear if they speak up, I just have trouble if they speak softly and mumble. How can I get them to speak up?

 
If you have difficulty hearing soft voices or sounds and speech seems unclear at times, then it is likely you have some hearing loss for some speech sounds.

To determine if you have a significant loss for some sounds you should have a diagnostic evaluation of your hearing by an audiologist. If the test results indicate that you would be a good hearing aid candidate then hearing aids will be recommended.

It is important to understand that hearing aids are designed to emphasize the sounds you have difficulty hearing. Most people who wear hearing aids can hear some sounds without hearing aids, but when they wear their hearing aids they hear more accurately which means communication is once again easy for both the listener and the speaker.
