That is what it is like to lipread when you cannot hear. Even with some hearing, lipreading is very difficult and demands great concentration. The lipreader has to stop what they are doing and give all their attention to what is being said. Wearing a hearing aid can be extremely helpful, but they don't restore hearing. A hearing aid simply amplifies noise and can sometimes distort sounds.
Background noises can become loud enough to make conversation impossible to follow.
Try to avoid holding conversations in noisy places. Switch off the television or radio. Move away from kitchen noises like the washing machine, clattering dishes and boiling kettles. Car journeys are usually not very good for conversation because of the engine noise. Before Speaking Attract their attention before you start speaking, as otherwise they may miss the first part of the sentence, which may be the clue to the rest.
