What is the LOWEST sound that humans can hear?

0 dBSPL

Explanation:

"The quietest sound a human can hear is 0 dBSPL. That might not sound all that amazing, but bear in mind that to hear is to detect vibrations of the eardrum, caused by pressure waves in the air. Zero dBSPL corresponds to a pressure wave of 0.000002 Pascals, which causes the eardrum to vibrate by approximately 10−8 mm." got it on the internet hope it helps
