sonic frequencies

sonic frequencies

Those frequencies of mechanical vibrations that are audible to the human ears. These lie between 20 to 20,000 hertz.

During drilling, the resonant energy is transferred down the drill string to the bit face at various sonic frequencies. Simultaneously rotating the drill string evenly distributes the energy and impact at the bit face.
Ultrasonic cleaners use environmentally friendly, nontoxic and non-flammable, water-based cleaning soaps and an energy-converting transducer that produces sonic frequencies approaching 40,000 cycles per second.
The AQUA-SCOPE allows an operator to choose between the ground and direct contact microphones to detect sonic frequencies. Electronic circuitry within the water detector amplifies the sound of the water leak and the operator interprets the differences in signal strength to localize the leak for fast pinpointing.
During drilling, the resonant energy is transferred down the drill string to the bit face at various sonic frequencies; simultaneously rotating the drill string evenly distributes the energy and impact at the bit face.
From echolocating bats with their incredibly high vocalizations to African elephants and their extremely low-pitched infrasounds, this mode of voice production seems to span four to five orders of magnitude across a wide range of body sizes and sonic frequencies.
As their recordings are detailed and therefore exactly located in relation to sonic frequencies, binaural microphones construct an aural position in a soundscape by tracking the distance of sounds from the aural position they create.
Pauline Stella Sanchez's work dazzles with blues and yellows so intense that with the right equipment they would probably prove to have sonic frequencies. Radial installations of diagrams on paper depicting circles, ovals, and Spyrographic bubblings, sometimes accompanied by glowing (fabricated) funsal growths and lumpy accumulations of Styrofoam and/or found materials, the work would seem to have some astronomical or astrological application, like an orrery for the moods of the next millennium.
The technology incorporates sonic frequencies that match the resonant energy of the ground, allowing the core barrel to easily advance in unconsolidated and difficult overburden formations.
