audible frequency การใช้

• Experiments were performed over the entire range of audible frequencies ( Greenwood 1961a ).
• Using audible frequencies makes more sense, says the QinetiQ specialist.
• The audible frequency range for young humans is about 20 Hz to 20 kHz.
• On " Superorganism ", musicians singing and playing instruments such as EEG cap into audible frequencies.
• Audible frequencies are 20 Hz to 20 kHz.
• In effect, the pulse length gets noise shaper which has lower noise in the audible frequency range.
• If these pressure waves are strong enough and within the audible frequency spectrum, a sensation of hearing is produced.
• So, to make audible frequencies, the " shape " of the dynamic system, along a closed path, is scanned periodically.
• One such source, capable of vibrating at audible frequencies ( 45 to 20, 000 vibrations per second ) is plasma.
• This effect cannot be achieved with conventional loudspeakers, because sound at audible frequencies cannot be focused into such a narrow beam.
• As the capacitance changes, the charge across the capacitor does change very slightly, but at audible frequencies it is sensibly constant.
• A reed's resonant frequency is a mid-range audible frequency of perhaps 300 Hz . which is an audio tone or tones.
• The difference frequency is then amplified and filtered in an'intermediate frequency'or i . f . amplifier before being converted back to audible frequencies again.
• Another technique, referred to as the sine sweep method, covers the entire audible frequency range, which can result in a broader-range, and higher-quality, impulse response.
• Equal-loudness contours indicate the sound pressure level ( dB SPL ), over the range of audible frequencies, that are perceived as being of equal loudness.
• The generally accepted standard range of audible frequencies is 20 to 20, 000 Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors.
• Each frequency band is tuned to the resonant frequencies of the sounding object to be modeled to avoid any discretization error at the dominant and audible frequencies.
• :: : Humans encounter that volume often enough at audible frequencies without turning into instant soup . talk ) 05 : 26, 1 January 2013 ( UTC)
• In comparison, the CD system offers a frequency response of 20 Hz 20 kHz ?.5 dB, with a superior dynamic range over the entire audible frequency spectrum.
