A recent article from Science Alert discussed a new technology
that can create “audible enclaves,” which are localised pockets of sound
that can be directed to a specific listener.
Although the
technology appears to use sounds that are captured by ears, it reminds
us of technology that has been used to experiment on people for decades:
voice-to-skull and the Voice of God.
Voice-to-skull is not the
only technology that has been around for a long time, members of the
public have also been experimented on with brain-computer interfaces for
years.
The article described newly published research that
introduces a technology that can create “audible enclaves,” which are
localised pockets of sound that are isolated from their surroundings,
allowing people to listen to music or have private conversations in
public without disturbing others.
The technology uses
self-bending ultrasound beams and a concept called non-linear acoustics
to send sound to a specific listener. The technique uses two ultrasound
beams at different frequencies that are completely silent on their own,
but when they intersect in space, non-linear effects cause them to
generate a new sound wave at an audible frequency that would be heard
only in that specific region.
The technology has many potential
applications, including enabling personalised audio in public spaces,
such as museums and libraries, and creating quiet zones to improve focus
in workplaces or reduce noise pollution in cities. It could also be
used in cars, offices and military settings to provide localised speech
zones for confidential conversations.
Although the technology appears to rely on functioning ears to receive the directed sound and so works differently, it is reminiscent of voice-to-skull technology and gives us occasion to raise a discussion about voice-to-skull and other experimental mind control technologies....<<<Read More>>>...
