Exempel på hur man kan använda INFRASOUND i en mening

• Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.
• Although the ear is the primary organ for sensing low sound, at higher intensities it is possible to feel infrasound vibrations in various parts of the body.
• Due to the wide range of signal properties and media they propagate through, specialized equipment may be required instead of the usual microphone, such as a hydrophone (for underwater sounds), detectors of ultrasound (very high-frequency sounds) or infrasound (very low-frequency sounds), or a laser vibrometer (substrate-borne vibrational signals).
• At various points of its evolution, it displayed textbook or record manifestations of supercell and derecho-related phenomena such as the right-mover supercell, evolution of supercells into a linear meso-scale feature which rapidly became a derecho, cumulonimbus with overshooting top and dome, bow echo, bookend vortices, regular and rotor downbursts, gust front, gustnado, rear inflow notch, classic derecho radar signature, effects of infrasound and atmospheric electricity, haboobs, and wind effects on bodies of water including seiches and exposure of bottoms of water features by the wind.
• Detailed analysis of GOCE's thruster and accelerometer data serendipitously revealed that it had detected the infrasound waves generated by the 2011 Tōhoku earthquake (whereupon it inadvertently became the first seismograph in orbit).
• In addition, females show increased alertness when hearing the infrasound signals produced by males' wing-shaking, which highlights how the two sexes use sonation to interact with each other.
• They included seismometer networks, air sampling for isotope traces, hydroacoustic soundwaves in oceans, and atmospheric infrasound waves; another idea was artificial satellites, although no one yet knew how many years or decades it would take to create artificial satellites.
• The earthquake also generated infrasound waves detected by perturbations in the orbit of the GOCE satellite, which thus serendipitously became the first seismograph in orbit.
• According to response measurements, pigeons are able to distinguish frequency changes of 1-7% in the infrasonic range, showing that the use of Doppler shifts for infrasound localization may be within the pigeon's perceptive capabilities.
• In 2002–2003, Angliss initiated and led Infrasonic (aka Soundless Music) - an experiment to explore the strange psychological effects of airborne infrasound (sound below 20 Hz).
• Burris-Meyer pioneered the use of "infrasound (sound with a frequency below the lower limit of human audibility)" in theater settings to "manipulate audiences' emotions subconsciously," wrote historian Prof.
