It raises the volume and helps improve quality of life to one who is hearing impaired.
My 93 year father has had hearing problems for most of his life. While spending about a month in rehab, he was provided with a Superear Se5000 Personal Sound Amplifier, which allowed him to hear better than he had in years (better than his first set of in-canal hearing aids ever was able to do). I purchased a unit for him, so that upon release, he would be able to hear well enough until his hearing is evaluated, and he is fitted with hearing aids.
The Superear unit is easy to operate. There is only one control, a wheel like that of a small transistor radio, perfect for one who is "electronically challenged" as my father is. The 1 AAA battery lasts for a long time before needing to be changed.
I tested the Superear unit on myself, and found that not only does it it raise the volume of sound significantly, but it does so in a way that does not cause feedback or other noises that would be annoying to the user.
