“The frequency that is thought to be most dangerous to humans is
between 7 and 8Hz. This is the resonant frequency of flesh and,
theoretically, it can rupture internal organs if loud enough. Seven
hertz is also the average frequency of the brain’s alpha rhythms; thus
this frequency has been described as dangerous but also relaxing.
...
We also see many deployments of sonic frequencies, used in order to
impact subjects negatively in varied military approaches such as
interrogation, crowd control and creating fear against enemies.
...
This technique has been applied to many non-warfare scenarios, which
allows us to understand the importance of it’s application. Many
musicians and directors have found ways of utilising neural
entrainment to initiate fear into the listeners. Movie Director Gaspar
Noe and musician Thomas Bangalter, used two differing bandwidths to
instil beta wave frequency to the audience in order to create a
feeling of tension in particular scenes of the movie Irreversible
(Stathatos, no date).
...
These techniques of applying 20,000Hz as a means of deterrent of said
‘self-defence’ devices allow for more primary research within this
field to be explored. As a result, this study will collect primary
research within this area to allow for a greater insight into the
application of these techniques.
