Understanding 42 Hertz Frequency

[@foxxlette2480]

I can hear it

[@DudsMotorShop]

Play at .75 speed or 1.75 speed for soothing harmonics.
I can hear this as clear as a bell at -40.Db; the house begins to vibrate around -5.0Db, and ear protection is worn above -20.Db.
Reminiscent of UH-1 Iroquois (Huey).

.75 sounds like an edm song

[@MrJohnsolomon]

No sound? Or maybe it's beyond my audible range.

What does this do

This sound is silent but its frequency will be felt within 10 minutes. Please listen with headphones."
