As dogs hear higher frequency sounds than humans, they have a different acoustic perception of the world. [24] Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs. Whistles which emit ultrasonic sound, called dog whistles, are used in dog training, as a dog will respond much better to such levels. In the ...
The third explosion has been reported as the loudest sound in history. [6] [7] [8]: 602 [4]: 79 The loudness of the blast heard 160 km (100 mi) from the volcano has been calculated to have been 180 dB. [9] Each explosion was accompanied by tsunamis estimated to have been over 30 metres (98 feet) high in places.
Acoustic sources within the "jet pipe" also contribute to the noise, mainly at lower speeds, which include combustion noise, and sounds produced by interactions of a turbulent stream with fans, compressors, and turbine systems. [1] The jet mixing sound is created by the turbulent mixing of a jet with the ambient fluid, in most cases, air.
The observed vibrations were then converted into sound and the frequency was sped up so the noise would be audible to human ears. Listen to the ear-shattering noise in the video above, and feel ...
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
The sound's source was roughly triangulated to , a remote point in the South Pacific Ocean west of the southern tip of South AmericaThe sound was detected by the Equatorial Pacific Ocean autonomous hydrophone array, [1] a system of hydrophones primarily used to monitor undersea seismicity, ice noise, and marine mammal population and migration.
The historical background of natural sounds as they have come to be defined, begins with the recording of a single bird, by Ludwig Koch, as early as 1889.Koch's efforts in the late 19th and early 20th centuries set the stage for the universal audio capture model of single-species—primarily birds at the outset—that subsumed all others during the first half of the 20th century and well into ...
