Call me 'virtually nobody', VN for short. At least you knew how to use a 35mm camera. Film has been coming back.
Let us fast forward. Taking a measurement microphone into the forest would yield anecdotal results. We are bombarded by infrasound in our environment. It is all around us, 24 /7 365. We can't shield for it / attenuate infrasound. Sound pressure waves with very long wavelengths are what we use to communicate with submarines. Goes through air, us, rock and water.
The rabbit hole is getting wider and deeper. The answer to the question of whether or not Sasquatch can generate and focus sound pressure waves is elusive at this time. Comments / claims are anecdotal.
Many animals have evolved to be able to generate and focus sound pressure waves and interpret the return signal. Elephants, Giraffes are the popular choices. Marine mammals have the best sonars. Better than man made sonars. Flying mammals as in bats echo range / locate. Not just mammals, the Oil Bird in South America can echo locate in total darkness with a resolution of about a 25 cent piece.
The old worn out saying is 'nature finds a way'.
