Frequency Induced Motion Sickness?

Click For Summary

Discussion Overview

The discussion revolves around the concept of frequency-induced motion sickness, particularly focusing on the potential effects of low-frequency sounds, such as infrasound, on human physiology. Participants explore claims regarding the existence of specific frequencies that may induce feelings of nausea or discomfort.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions the validity of claims regarding frequency-induced motion sickness and asks for references to support such statements.
  • Another participant suggests that the discussion may be referring to infrasound, which is characterized by low frequencies, and mentions its presence in certain musical instruments like pipe organs.
  • A participant shares an article that discusses the effects of infrasound, indicating that there is some literature on the topic.
  • One participant recounts an experience in a lab demonstration where low-frequency sounds caused some individuals to feel nauseous, while others were unaffected, suggesting variability in response to such frequencies.
  • Another participant mentions a "spy shop" product that claims to emit a frequency designed to induce sickness, raising questions about the legitimacy of such claims.
  • A participant provides a link to a comprehensive overview related to non-lethal weapons and their effects, which may include discussions on sound frequencies.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the claims regarding frequency-induced motion sickness. There are multiple viewpoints presented, with some participants expressing skepticism about the claims while others provide anecdotal evidence and references to support the discussion.

Contextual Notes

There are limitations in the discussion regarding the definitions of terms like "motion sickness" and "infrasound," as well as the lack of empirical evidence provided to substantiate the claims made by participants.

Frequency Induced Motion Sickness?

Is it true what they are saying? They are now able to send out a frequency, and it makes you feel like you have motion sickness? How is it possible to create this frequency?

Who are "they" that are saying this? Do you have some sort of reference to back up the statement that someone is even making this claim?
 
I believe he is referring to infrasound. It's low frequency. Josht, is this what you are referring to? A lot of pipe organs in churches produce infrasound. I have some articles on it I can probably dig up. We had a long discussion about it here a couple of years ago.

I'm not to sure actually, I went to a "spy shop" to kill some time and they had a little speaker and it said "the vomit frequency" and the caption said that it emits a tone so low that it makes you sick to your stomach.
 
This is the most comprehensive overview I could find on a quick search:

Long ago, before law suits, I did lab demonstrations for a professor. In one of these, I used a large Klipsch speaker array and a good low frequency amp (an old McIntosh) to run through the range of about 2-20Hz in order to vibrate objects about the room. Invariably, someone would grasp their stomach or cross their legs and charge for the bathroom. Most students were unaffected. Today, no one in their right mind would do such a demo.
