Helmholtz resonance, also known as wind throb, refers to the phenomenon of air resonance in a cavity, an effect named after the German physicist Hermann von Helmholtz. [1] This type of resonance occurs when air is forced in and out of a cavity, causing the air inside to vibrate at a specific natural frequency.
An important type of resonator with very different acoustic characteristics is the Helmholtz resonator, named after the German physicist Hermann von Helmholtz. Essentially a hollow sphere with a short, small-diameter neck, a Helmholtz resonator has a single isolated resonant frequency and no other resonances below about 10 times that frequency.
Helmholtz Resonators: Tools for the Analysis of Sound. Invented by Herman von Helmholtz, these instruments were used to analyze the composition of musical and speech sounds by means of 'resonances'. Later improved by Rudolph Koenig (1832-1901), they were an essential tool for the 19th century acoustician.
May 31, 2023 · Most people who have been around acoustics or acousticians have heard of the Helmholtz resonator. In this article, Honeycutt discusses the extraordinary scientist for whom this device is named - Hermann Ludwig Ferdinand von Helmholtz (1821–1894) - and examines how the resonator works, as well as its uses.
Sensations of Tone. Helmholtz resonator, p. 121, fig. 32. On the Sensations of Tone as a Physiological Basis for the Theory of Music (German Die Lehre von den Tonempfindungen als physiologische Grundlage für die Theorie der Musik ), commonly referred to as Sensations of Tone, is a foundational work on music acoustics and the perception of ...
Helmholtz described in his 1862 [sic] book, On the Sensations of Tone, an apparatus able to pick out specific frequencies from a sound. The Helmholtz resonator, as it is now called, consists of a rigid container of a known volume, nearly spherical in shape, with a small neck and hole in one end and a larger hole in the other end to admit the sound.
Last photograph of von Helmholtz, taken three days before his final illness The Helmholtz resonator (i) and instrumentation In 1863, Helmholtz published Sensations of Tone , once again demonstrating his interest in the physics of perception.
