i have used mindstim on a regular basis, as well as the joudry product and the samonas product which incorporate the tomatis technology.
for a total of hundreds of hours over a few years.
and no negative side effects to report.
only positive effects from using these products....less need for sleep, increased energy, greater concentration and creativity, greater personal awareness.
my friends and family members have also sampled these tracks on occassion. and not a punctured eardrum anywhere in sight.
furthermore, these products are sold by toolsforwellness, which i have always found to be an extremely ethical company, which doesnt sell anything the employees do not use themselves. i find it highly unlikely that they would continue to offer these products if there were reports from users indicating some kind of result like your friend described.
additionally, there are books written about the tomatis procedure, indicating the overwhelming positive effects it has had in the lives of many individuals. apparently your scientist friend ignored, did not seek out, and was not made aware of this evidence when she supposedly made this generalized and uninformed remark to tomatis that the technology does not work.
since she is capable of overgeneralizing like this without looking at all the evidence, only her tiny little personal fraction, i am not inclined to trust anything else she says.
as far as her supposed encounter with tomatis, i believe that your friend is lying/fabricating the story out of whole cloth, or at the very best, grossly misrepresenting what tomatis himself actually said.
if she actually did use something and it produced the results you are describing, then i dont believe it was an actual professionally produced tomatis soundtrack.
if your friend disagrees, perhaps she can explain the mechanism of action by which a classical music recording with low frequency sound filtered out would be capable of puncturing a human eardrum eardrum.
she oughtta have a pretty good explanation for this, being that shes a scientist, after all.
