Scientists ignored snow microstructure’s acoustic effect until the 1950s
Evidence
It was not recognized until the 1950’s that the physical properties of the snow and snow metamorphism had an effect on the acoustic properties of the snow. Careful experimental measurements were reported by a number of Japanese researchers,10–18 who conducted short-range acoustic measurements using loudspeakers and continuous wave ~CW! sources in and above a snow cover, and reported differences between the propagation characteristics of ”new” and ”compact” snow. — Donald G.
