| Seismologists and volcanologists use both seismic and infrasonic signals to monitor volcanic activity. |
|
| He says he once invited people to spend a few minutes in a container he was pumping with infrasonic sound. |
|
| The routine up-and-down movements of the waves act as a giant loudspeaker, pushing the air at infrasonic frequencies. |
|
| Rhinoceroses produce infrasonic vocalizations, though their vocal repertoire is still largely undocumented. |
|
| Powerful infrasonic calls enable them to send messages and warnings, sometimes over long distances. |
|
| The paralysing effect of a tiger's roar is said by some to come from its infrasonic content. |
|
| One psychologist thinks that the odd sensations that people attribute to ghosts may be caused by infrasonic vibrations. |
|
| Just as seismic waves travel through Earth, infrasonic waves travel through the air. |
|
| Singing whales appear to slalom from one geographic feature to the next using the echoes of their intense, infrasonic voices to navigate. |
|
| This version is not recommended for audio applications because of the possibility of infrasonic noise problems. |
|
| The frequency band extends over 13 octaves starting in the infrasonic zone. |
|
| My design is similar to a vortex ring gun, but I just can't get the infrasonic transmission to register at 0.001 hertz. |
|
| Using calls that have infrasonic fundamental frequencies, female elephants are able to communicate with large numbers of specific individuals over long distances. |
|
| In addition to meteors, infrasonic energy is generated by chemical explosions, supersonic aircraft, tornadoes, landslides, earthquakes, and volcanoes. |
|
| It has been argued that weapons that utilize infrasonic frequencies can cause nausea, disorientation and bowel spasms. |
|
| The seismic signals varied a lot from one place to another, whereas the infrasonic ones were more consistent. |
|
| Elephants have very deep voices, mostly infrasonic, with only some of their sound vibrations in the range of human hearing. |
|
| From this lesson, name an animal that uses infrasonic sounds. |
|
| Dr Garcés and others are also working on computer models that describe what is actually going on inside a volcano, to see if those processes produce the kinds of infrasonic waves observed. |
|
| In addition, the vocals of northern elephant seals may produce infrasonic vibrations. |
|
|
|
| Detect and analyze elephant sounds, including infrasonic calls that are inaudible to human ears, to help researchers and conservationists generate abundance estimates and deduce population structure from acoustic information. |
|
| The CMC 6 microphone amplifier normally has a gradual rolloff in response below 20 Hz to guard against infrasonic disturbances from various sources such as air movement and vibration. |
|
| In another decade or so, Dr Garcés reckons that it might be possible to integrate infrasonic, seismic and other readings with a computer model to predict the time of an eruption to within a day or two. |
|
| I am requesting all files and documents pertaining in whole or in part to, non-lethal technology based on infrasonic oscillators, and electromagnetic radio frequency radiation devices to affect biological targets. |
|
| Indeed, traditional instrument tone quality bas never been the aim, on the contrary new tones have been created ranging from infrasonic to ultrasonic vibrations. |
|
| Additionally, these chest wall and body hair vibrations have also been shown to occur in the infrasonic range. |
|
| Some additional topics explored are family structure, bonding, infrasonic communication, mating, emotions, intelligence and evolution. |
|
| Mysticeti have exceptionally thin, wide basilar membranes in their cochleae without stiffening agents, making their ears adapted for processing low to infrasonic frequencies. |
|
| Infrasonic calls can travel effectively for miles though air, land and water to the animal's family members. |
|
| Euromi has placed thousands of Nutational Infrasonic Liposculpture systems around the world. |
