I began using the aplication called "いびきラボ" on smart phone.
It record my snore while I sleep.
I used it last night,right away.
And today,I checked its my sounds.
My snore was so loudly noise,so I had a shock.
When I'm listening them,I caught a different sounds with my that.
Same kind noise at a bit distance.
I wrote this blog in English,because my wife might angry.
