Binaural beats are created by presenting two
different tones at slightly different frequencies separately
into each ear. This auditory stimulation has been suggested
to influence behavior and cognition via the process of
cortical entrainment. The portable binaural beat device
used in this study was designed to produce 500 and 515 Hz
slightly different frequencies separately into each ear to
form a given low 15 Hz binaural beat in brain hemisphere.
In this study the generated binaural beat was 15 Hz as
determined by digital storage oscilloscope. This portable
device is 5x6x3 cm in size and weighs 100 g which can
easily be taken to any laboratory. The device was examined
by Digital Storage Oscilloscope to confirm its capacity in
producing the mentioned beta wave frequencies prior to
our application with four participants. Binaural beat audio
was also studied as an alternative frequency source, for
larger sample group that involve learning activities or
moving around. The quantitative electroencephalograph
(qEEG) method was used to convert the brainwave signal
into brain mapping for apparent understanding of how
frequency stimulation affect brainwave and to confirm the
existence of the binaural beats created in brain hemisphere
at 15 Hz. All participants are in age group of 26 - 40 years,
who represent the majority of the chemical users’ age
group in earlier research. The brain mapping evidently
illustrated the result of this research that the 15 Hz
binaural beats tremendously stimulated Brainwave
Activity and neural connectivity in participants.
