Subject: Re: How do I measure resonance? From: Bob Masta <audio@xxxxxxxx> Date: Tue, 13 Mar 2012 08:52:04 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Proceed with caution when driving body resonances. I don't know about the head specifically, but there are well-known studies from the early space-race era where body resonances were explored. Certain low frequencies (7 Hz in particular) caused violent gastrointestinal problems as the internal organs gyrated around under resonance. I also recall a much earlier experiment with a large low-frequency steam whistle which caused illness when tested on unsuspecting factory workers.
