15 YO DS has always been teased a bit about 'being deaf', but always put down to just being a bit dopey at times (in the nicest possible way of course).
Today, I was with him in his room and the crickets that he feeds to his pet lizard were chirping and I asked if it ever disturbed him at night. He had no idea what I was talking about. Couldn't hear it at all.I got DS1 and DS3 in to listen, just to check it wasn't a frequency thing that adults could hear but not children, but no they could also hear it clearly.
Now, these crickets certainly aren't loud, but I could hear them quite easily.
Does it sound like it needs investigating or is this within the norm?
