New noninvasive neurotechnology for vets: Study finds therapy using sound is effective for PTSD – without the side effects of medication


The researchers used high-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM), or neurotechnology that offers “noninvasive, closed-loop, acoustic stimulation approach.” ... This acoustic stimulation approach lets the brain “listen to itself through an acoustic mirror,” shared Tegeler. "...

High-speed hand dryers in public restrooms found to emit INSANE levels of ear-damaging noise


As part of the study, the research team conducted an acoustic test on various high-speed driers and found that the sound decibels produced by these machines were 11 times higher in a typical public restroom compared with a product testing laboratory. ... “Manufacturers tend to test hand dryers in ultra-absorbent acoustic laboratories which is perhaps why actual sound levels are so much higher than those advertised.
