Wave intensity and periodicity also timbre, John. All different at
each site. Since 1979, all my recordings are calibrated to known and
repeatable references so I've got a base-line reference and something
to compare to. I haven't "studied" this phenomenon. And there are so
many permutations (air temperature, wind, swells, wave height,
current, beach rake, salinity, and so many other factors) that it
would be great fun to get a better handle on what may well be
something else to note in our lovely sonosphere. My guess is that
Coney Island is as distinctive as the beach at Big Sur.
