infrasonic

[ˌɪnfrəʊˈsɒnɪk ]

Definition

Context #1 | Adjective

sound frequency

Infrasonic refers to sound waves with a frequency below the lower limit of human audibility, typically below 20 Hz. These low-frequency sounds can be produced by natural events like earthquakes or by man-made sources such as engines. Infrasonic waves can travel long distances and are often used in scientific research to monitor seismic activity.

Synonyms

low frequency, subaudible, unhearable.

Examples of usage

  • Whales communicate using infrasonic calls.
  • Infrasonic vibrations can be felt during an earthquake.
  • The infrasonic waves generated by the jet were detected miles away.

Interesting Facts

Nature

  • Some animals, like elephants and whales, communicate using infrasonic sounds over long distances.
  • Earthquakes produce low-frequency waves that can be classified as infrasonic and can be detected by specialized instruments.

Health and Safety

  • Infrasonic sounds can sometimes cause physical sensations or discomfort, such as feelings of anxiety or unease in humans.
  • Certain medical devices, such as ultrasound machines, use sound frequencies, which includes some low-frequency sounds to produce images.

Technology

  • Infrasonic sensors are used in various technologies for monitoring and detecting environmental phenomena, such as volcano eruptions.
  • Military applications have utilized infrasonic waves for surveillance and communication, particularly in remote areas.

Culture

  • Some modern composers have experimented with infrasonic frequencies to elicit emotional responses in their audience.
  • Films have occasionally used low frequencies to create suspense or tension without the audience knowing the exact cause, enhancing the viewing experience.

Origin of 'infrasonic'

Main points about word origin

  • The term 'infrasonic' comes from 'infra', meaning 'below', and 'sonic', from the Latin 'sonus', meaning 'sound'.
  • It was first used scientifically in the mid-20th century as researchers began to understand low-frequency sound waves.

The term 'infrasonic' is derived from the Latin prefix 'infra-', meaning 'below', and 'sonic', which originates from the Latin 'sonus', meaning 'sound'. This term was first introduced in the scientific community in the mid-20th century, primarily in studies related to acoustics and sound waves. It was recognized as referring specifically to frequencies lower than those detectable by the human ear. The growing understanding of sound waves and their effects on the environment has led to increased interest and research in infrasonic phenomena, particularly concerning its role in natural events and its potential applications in technology and science.
