Sound Barriers

Inferno Sound Barrier range

The patented sound barrier produces a complex spectrum of constantly oscillating tones which have a highly disruptive effect on the human brain.  They were originally designed for military use!

Result: confusion, inability to concentrate, nausea, disorientation and vertigo. A combination that renders the protected area uninhabitable, closing the window of opportunity that burglars need.

Sound barriers have been installed worldwide in a diverse range of situations from warehouses to the cargo area of vehicles, nuclear reactors to summer houses.

The US Department of State recently commissioned the sound barriers as the final layer of protection in US embassies worldwide!
