Did you know that the wind, one of the four elements of nature, carries wide-band noise. What is wide band noise? Well, it’s pretty self explanatory, a noise in a wide band spectrum with more frequencies. In simple words: a sound that contains many frequencies at the same time. Examples?! The wind The rain The ocean waves Yes. Mother Nature scores again!! Technically: - White noise → equal energy per Hz - Pink noise → more low frequencies (often more natural) - Brown noise → even deeper, heavier lows Wind noise sits closer to pink and brown noise, not pure white.

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.
