Cymatics (from Ancient Greek: κῦμα, romanized : kŷma, lit. 'wave') is a subset of modal vibrational phenomena. The term was coined by Swiss physician Hans Jenny (1904–1972). Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of ...
Hans Jenny (cymatics) Hans Jenny (16 August 1904 in Basel – 23 June 1972 in Dornach) [1] was a Swiss physician and natural scientist who coined the term "cymatics" to describe acoustic effects of sound wave phenomena.
Bessel function. Bessel functions describe the radial part of vibrations of a circular membrane. Bessel functions, first defined by the mathematician Daniel Bernoulli and then generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel's differential equation for an arbitrary complex number , which represents the order of the Bessel ...
Radio Folkestone, previously known as 105.9 Academy FM until 11 May 2024, is a community radio station serving the town of Folkestone in Kent, which launched on 31 March 2011. [1] The station broadcasts 24 hours a day on 105.9 FM. In spring 2015 OFCOM announced that rules relating to on-air advertising for community radio stations would change ...

She became known as the first host (alongside A. J. Calloway) of Black Entertainment Television 's 106 & Park until 2005. She was later as a disc jockey at KKBT ...
The properties of an idealized drumhead can be modeled by the vibrations of a circular membrane of uniform thickness, attached to a rigid frame. Due to the phenomenon of resonance, at certain vibration frequencies, its resonant frequencies, the membrane can store vibrational energy, the surface moving in a characteristic pattern of standing waves.
