masking

mask??masking??
we can apply facial mask on our face as a part of skin care routine..

or we can also wear an artistic mask to attend party..

hm..do you know that masking is used in the clinical testing also??
one that you'd feel familiar with is the masking used by optometrist when you went for visual check up..

do you know why one of our eyes is closed during the visual testing?
yes, to avoid the other better eye from helping the worse eye in carrying out their visual task..
through masking, we could know your exact visual level..

when it comes to sound..
have you ever heard of auditory masking?
new to you??
hm..
how can we determine the hearing threshold of your worse ear huh??
since you cannot instruct our ears to stop listening even just for a moment..
how to avoid your better ear from helping your worse ear??

well..all i can say is it's complicated (at least for now, for myself)..
sighed..
learning about it since the beginning of this semester..
now im still confused..
nvm, sooner or later i'll master it!! (^_~)
