My mother as a teenager listened to her transistor radio all the time, it was a new thing when she was young. She held it up to her ear and it was turned up very loud now she suffers from fairly profound hearing loss but only in a specific high range she can hear low bass normally. If you talk to her and then turn on a tap to get a glass of water the conversation over, the fridge motor comes on conversation over, any…
Is there a way of highlighting how often she says "what?" like a tally chart? I would try that with my mum to get a message across. She'd likely be deeply offended, but I think the message would get across.
