I've googled my problem but it doesn't come up with anything useful so I thought I'd try on here.
There is a clock in the living room which makes quite a load ticking noise but I can't hear it! I can hear everything else perfectly but not this clock. I was just wondering if my brain is drowning it out (or it's a more serious problem) and if anyone else has experienced similar?
This clock has been in my house since I was born (I think) and I have heard it previously but I can't hear it anymore.
