(1) I compose on synths, I perform with them; sometimes I watch a sunset with an 80- hertz sawtooth wave humming in the background.

(2) U251cu00f6u251cu00e7u251cu2510We shook the top with a motor to produce a displacement of about 1 millimeter at 10 hertz ,u251cu00f6u251cu00e7u251cu00fb says Giazotto.

(3) At random times the program changed the dot's frequency up or down by up to a few tenths of a hertz .

(4) Most pneumatic isolators operate effectively above several hertz , but at their natural frequency they actually provide some amplification.

(5) It now occurs to me that the best analogy for Google hits as a measurement term is not hertz or joules or pascals, but degrees Celsius.

(6) It was 1,660 hertz (cycles per second), in the range of frequencies expected to emanate from an exploding star.

(7) The answer, Zuckerwar explains, is that each one generates silent infrasound - long sound waves at a frequency below 20 hertz .

(8) At the moment, for example, the two neutron stars in the Hulse-Taylor binary are emitting gravity waves at a frequency of 10-4 hertz as they circle one another every eight hours.

(9) Frequencies of hundreds of megahertz were selected with a resolution of just a few hertz , while the magnetic field had to be homogeneous to within one part in a billion.

(10) When he measured the infrasound in the laboratory, the showing was 18.98 hertz - the exact frequency at which a human eyeball starts resonating.

(11) And he actually employed a 27 hertz frequency through the first part of the film to induce unease.

(12) The sounds and charges transmit in the low frequency range of 20 hertz , which is barely audible to the human ear.

(13) We see frequencies of hundreds of hertz , or hundreds of revolutions of the disk per second.

(14) A gravity wave with a frequency of 1,000 hertz , for example, spans nearly 200 miles from peak to peak.

(15) The praying mantis' ultrasonic hearing picks up frequencies above 20,000 hertz - just beyond the range of humans - through a single ear located in the center of its chest.

(16) Different frequencies, measured in hertz , or cycles per second, indicate different levels and types of activities.

(17) But the only common instances of animal infrasound - inaudibly low frequencies - were the 20 hertz songs of fin and blue whales, and these proved fiendishly hard to investigate.

(18) The other instrument is sensitive to even lower frequencies, ranging from less than 0.1 to 400 hertz .

(19) In most systems, the fundamental frequency is 60 hertz .

(20) The selection of the frequency shift is 100,000,000 hertz .
