My daughter has this problem too. At first I thought it was funny and said she should get her hearing checked out. Now saying that I’ve probably passed it on to her, sometimes I hear things others don’t, like a strip light making a noise, or a fan running in the next apartment (it sounds like someone drilling through the wall!). My daughter’s problem is usually with chewing, yawning, breathing (if we’re out walking) and although she can be at her wits end with me, I’m not quite there – yet! But now I know what the problem is I can only try and alleviate it – by not breathing!!
