What Effect Does Low-Frequency Sound Have on Humans?

Not only are low-frequency sounds associated with human illness, but they’re also associated with annoyance, lack of ability to focus or concentrate, and the inability to retain information (memory issues). 

It is believed by some people that some individuals operate at a higher frequency while others operate at a lower frequency, based on unmitigated stress levels or unresolved feelings that the individual inevitably exudes in social interactions with others. This means that one stressed-out person can pass that lower frequency and negative attitude on to anyone else they encounter. 

Coincidentally, many animals communicate displeasure or anxiety with lower frequency communication sounds such as groans, hissing, growls, or snarls. Low-frequency sounds are not only shown to be psychologically distressing to humans—they can create physical fatigue and uncomfortable pressure on the eardrum as well. 

Ambient low-frequency sounds are associated with increased mistakes in the workplace as well as a general sense of discomfort in humans. This is because low sound frequencies conflict with the natural frequencies produced by the human body.  

Here is the full list of negative symptoms associated with low-frequency sound exposure: 

  • Loss of sleep
  • Irritability
  • Fatigue
  • Loss of concentration
  • Nausea

The government took the application of low-frequency sound as a weapon even further, incorporating infrasonic sound technology into crowd dispersal vehicles such as LRAD tanks. These sonic tanks produce a low-frequency sound designed to induce immediate nausea and dizziness in a rioting crowd through sonic warfare. 

If the healing capability of high-frequency sounds is in question in the medical and holistic communities, there can be no question of the sickening capability of low-frequency sounds when incorporated into acoustic weapons.
