Your heartbeat sits around 1–2Hz.
At 60bpm, a regular heartbeat it sits exactly at 1Hz
100bpm in an adult corresponds to 1.67hz
Up to 180bpm it reaches 3Hz and at
250bpm(extremely high for a human) it peaks to 4.17Hz.
That’s because below 20Hz the bass frequencies are not heard but felt. That’s when our body becomes the first listener.
