Ear protection

Yesterday at school, it was suggested to Joey that he try wearing "ear muffs" - not the winter kind, but the ear protection kind, in an attempt to block out some sound. I spoke with him at length about it last night; he said it helped a bit, but that he could also hear "someone humming" in the classroom. I tend to think that this was, instead, muffled sounds of people's voices, but as long as the "humming" isn't too distracting for him, this may be a good way to give him a break from the noise. And as long as it doesn't make him a target, or make him stand out in a negative way or a way he's uncomfortable with.
