The chosen solution in his thesis are Helmholtz resonators, which are a kind of acoustic spring. Using a carefully selected opening into the cavity, frequencies can be filtered out, and ...

A cavity-type resonator so constructed that it will vibrate only at a particular frequency, giving off little energy to the outer medium, and therefore resonating for a considerable length of time. It ...

Honda employed the concept of Helmholtz resonance, the phenomenon that generates sound when a person blows across the top of ...

See: EIGENTON, HELMHOLTZ RESONATOR, RESONANCE, RESONATOR. Compare: ACOUSTIC RADIATION. For instance, various body cavities and organs may be set in VIBRATION by INFRASONIC vibration and low frequency ...

The Helmholtz Space Life Sciences Research School (SpaceLife) is funded by the Helmholtz Association (Helmholtz-Gemeinschaft) for a period of six years (beginning in April 2009) and receives ...

The quest for a material with a high-quality factor and built-in piezoelectricity Most of the best-performing nanomechanical resonators are made from tensile-strained silicon nitride, a material ...

The Helmholtz Association of German Research Centres is a union of 15 science, technical, biologic, and medical research centers within Germany. Collectively, the association employs more than ...

Kelvin-Helmholtz instability creates beautiful wave-like cloud patterns in the sky, or billow clouds. Different layers of the atmosphere can have different densities with air moving at different ...
