Engineering Physics Annotation << Back INVESTIGATION OF THE INFLUENCE OF THE GEOMETRY OF THE HELMHOLTZ RESONATOR ON THE ATTACHED LENGTH OF THE THROAT R.A. VETOSHKO, Е.А. MARFIN, A.G. GAVRILOV The infl uence of the shape of the Helmholtz cavity chamber on the size of the attached throat length (end correction) was investigated. The frequency of the resonator’s natural vibrations was determined experimentally and the value of the attached length of the throat was calculated from it. The infl uence of the length and diameter of the throat on the value of the attached length for the spherical, cylindrical and cubic forms of the cavity chamber is determined. A linear dependence of the value of the terminal correction for resonators with spherical and cylindrical chamber shapes on the diameter of the throat and the absence of dependence on its length are established. There is a linear dependence of the end correction for the resonator with the cubic shape of the chamber from the product of the length of the throat to its diameter. Key words: acoustic resonator, resonance curve, natural frequency. Contacts: E-mail: roma95mail@yandex.ru, E-mail: marfin_ea@mail.ru, E-mail: agavrilov05@mail.ru Pp. 12-19.
