Captioning on the tv needs more training. I find the font too small and speakers talk like auctioneers so fast that it is hard to understand every word.
I use a Willams Sound Pocketalker with a TV line that holds a microphone attached to the TV and I wear head phones. I can hear every word as if the speaker is on my shoulder speaking into my ear. With the Pocketalker, it controls the volume and the tone of the voice. If interested ask for Cathy at Williams Sound 1-800-328-6190. I also use a Clarity Alto Plus landline phone. It has volume and tone control. She helped me when my equipment broke down after using it for 10 years. I am 88 years old and have been hard of hearing since I was 4 years old. Remained in the public schools, went to The Ohio State University in Columbus, OH. graduated in 1959 and worked as a microbiologist for 35 years for the Ohio Dept. of Agriculture. There was no support for people with hearing loss only those who use Sign Language.
