Check the link to hear the Landers quake at 80 X speed (so it's in the human range).

Note that the clicking sound attributed to the p-wave is analagous to what "The Hum" people hear...like a loud diesel truck clicking/clacking...so there are some similarities it seems...at least part of the time anyway.
