A colleague of mine has finally located the original NASA report paper that Tandy based his 'eye-ball' resonance suggestion on which provided the basis for all the ideas about infrasound and anomalous haunt-reports.
I have had a quick look - and it's highly dubious. No infrasound was used in the NASA report - skull & body vibration was employed by applying 0.5 - 1.0G vibration to observers. This is hardly the same thing. In addition, my colleague noted that the data do not really look like 'resonance' phenomena at all.....
The whole assumption Tandy made was based on this paper (which we have questioned elsewhere). It seems there really is no evidence at all that true-infrasound (IAV - inaudible air vibration) has any implications for anomalous cognition.
Based on this, there seems to be little need to measure it. It appears to be a total irrelevance. Any thoughts?
