Ear Defenders

If you can afford them, noise cancelling headphones might do your daughter better. They can produce a background white noise that can reduce outside sound, while allowing her to hear whatever she wants to listen to on her phone, if she has one. If your phones have data plans that can connect to wifi anywhere, you can use apps like Skype or Discord to be in a free call with your daughter, so that she'll be able to hear you while blotting everything else out.
