i have been having this problem for a few years liao.. it all
started when my mum brought an insect repellent(those type which
give out damn high frequency sound 1 to scare off mosqitoes 1)..
can u guys hear this mosqitoe repellent sound i mentioned above?
damn irritating..
it's that i can't stand all high pitch/frequency sounds.. i can
even hear very high frequency sounds which non of my family members
can..
got 1 time i go shopping center in bugis area.. when i walked into
this particular section, there will be this damn cloody high
frequency sound which nearly blow my head off.. then my cousin, sis
and aunt is like "where got sound? and laugh at me.."
then everytime i hear any high pitch sound, my head will starts to
ache.. damn..
