helmholtz resonator การใช้

• Resonant absorbers are further divided into panel absorbers and Helmholtz resonators.
• A Helmholtz resonator is unusually selective in amplifying only one frequency.
• These panels use a combination of three Helmholtz resonators and a wooden resonant panel.
• They noted that at lower speeds, the cylindrical volume responded as a Helmholtz resonator.
• This means that, unlike a flute or Helmholtz resonator, this weakens tonal production.
• In electronics and radio, Helmholtz resonators.
• :: : If your building is large enough then you may notice a Helmholtz Resonator.
• This configuration is often combined with the use of Helmholtz resonator used as a passive noise-control device.
• The Helmholtz resonators in the wheels were touted as a " world's first " for a passenger vehicle.
• In some two-stroke engines, a Helmholtz resonator is used to remove the need for a reed valve.
• The lens consists of a network of fluid-filled cavities called Helmholtz resonators that oscillate at certain sonic frequencies.
• In similar Helmholtz resonator instruments with a narrow cone shape, like the Gemshorn or Tonette, some partial overtones are available.
• A type of Helmholtz resonator tuned to either the fundamental frequency of the sound to be analyzed, or one of its harmonics.
• Some combustion chambers, such as those of the SSME, use Helmholtz resonators as damping mechanisms to stop particular resonant frequencies from growing.
• The tongue is long and thin, reaching as much as, and has numerous long Helmholtz resonator and enhance sensitivity to certain frequencies of sound.
• The term Helmholtz resonator is now more generally applied to include bottles from which sound is generated by blowing air across the mouth of the bottle.
• The Hang uses some of the same basic physical principles as a steelpan, but modified in such a way as to act as a Helmholtz resonator.
• Miller also produced the first aluminum pistons, developed the aluminum alloys still used in engine development today, and the first carburetors and induction system to use Helmholtz resonators.
• By one definition a Helmholtz resonator augments the amplitude of the vibratory motion of the enclosed air in a chamber by taking energy from sound waves passing in the surrounding air.
• The theory of Helmholtz resonators is used in motorcycle and car exhausts to alter the sound of the exhaust note and for differences in power delivery by adding chambers to the exhaust.
