Regardless of the frequency spectrum of noise exposure, noise-induced hearing loss usually occurs first in a frequency of approximately 3,000 to 6,000 cycles per second
. The extent of noise-induced hearing loss will progress and affect other frequencies unless exposures are controlled.
The feature of cycles per second
can be more easily understood and perceived with music than with random sound (noise).
The clock cycle within the FPGA is 50 million cycles per second
. Given the 40,000 logic blocks inside an FPGA, this yields a peak processing capability of 2 trillion tasks per second--more than 600 times as many as today's fastest CPUs are capable of achieving (as of this writing, Intel's fastest microprocessor rated 3.4 billion instructions per second).
(MHz stands for MegaHertz, or Millions of Cycles per Second
, while GHz stands for GigaHertz, or Billions of Cycles per Second
.) In the U.S., all Wi-Fi products ship with configurable channels, from 1-11.
Ultrasound, which he discovered worked best at around 30,000 cycles per second
, produced a series of pressure waves that hammered against the tough spore wall.
It's very similar to a wind chime or guitar string, each of which vibrates at a specific frequency (cycles per second
) when struck.
Most sounds sensed by humans range between 20 Hertz and 20 kHz (20 cycles per second
to 20,000 cycles per second
Even though the control modules each have several control cycles per second
, the information can take several seconds to reach the central computer.
During intermission, the concertmaster strikes a tuning fork that emits a tone at exactly 440 cycles per second
, a perfect "A." The concertmaster tunes his or her violin to this baseline and then retunes the entire orchestra.
Existing test standards can be used with the evolution, says MTS, and the machine is available with 150 mm (5.9 inches) or 300 mm (11.8 inches) of total displacement, up to 5 kN (1120 lbs) maximum force, and the capability to apply up to 15 test cycles per second
Instead, a high-speed motor spinning at 250 cycles per second
generates sonic vibrational energy that causes the attachments to resonate from side to side, creating small but high-speed cleaning strokes at a rate of 31,000 per minute--up to 10 times faster than a standard electric toothbrush.
The US computer chip maker Intel Corp has introduced its fastest-yet PC microprocessor - an Intel Pentium 4 processor that operates at 2GHz, or two billion cycles per second
