I hope you can get the remote repaired. Was that a remote control or a remote microphone? The Pocket Talker should help, however, it helps best if the mike can be as close to the speaker's mouth as possible. Not always easy to do. If you sister is open to learning, try this: Make a list of ten 3 or 4 syllable words like motorcycle, telephone, educate, etc. Then eliminate all the consonants from the words and have your sister tell you what the words are. Most hearing losses are high frequency losses, consonants define words, and most are high frequency sounds. Vowels give words power. We hear most of those but miss the clues to the word meaning. Consequently, we are always trying to keep up. While our minds are trying to figure out one sentence, the speaker is on another one, or even another topic. This is what causes auditory fatigue. If you give them the word with only the consonants they will figure it our fast. Here's one: _o_o__y_ _e vs m_t_rc_cl_ or an easier one like: _u_ _ _e instead of p_rpl_

In presentations, I sometimes use the Gettysburg Address. I have someone read the first paragraph while a timer keeps track of how many seconds it takes the person to read it. Then try the second paragraph that has a few missing consonants. The time will be longer because they have to figure out what is missing. Then try a third paragraph with more consonants missing. Even with a familiar passage it will take considerably more time. That often helps the hearing family member understand what is happening.

Our hearing loss is frustrating to others too. It does help if they understand what's happening.
