Attempts to demonstrate the existence of a "brown note" using sound waves transmitted through the air have failed.
Air is a very inefficient medium for transferring low frequency vibration from a transducer to the human body.
Test subjects suffered motor ataxia, nausea, visual disturbance, degraded task performance and difficulties in communication.
Test signals were generated by a SIM 3 audio analyzer, with its software modified to produce infrasonic tones.
[7] The test subjects all reported some physical anxiety and shortness of breath, even a small amount of nausea, but this was dismissed by the hosts, noting that sound at that frequency and intensity moves air rapidly in and out of one's lungs.
