PS. If you are not aware db scale is not linear.
Every 3 db increase is double the sound energy of the previous. so 103 db has twice the enery of 100 and 4x the energy of 97.
But peoples perceived loudness is different to energy. It takes about 10 db for someone to think its twice as loud. so 103 wont seem twice as loud but 110 will. When it actually has over 10x the sound energy.
