Helmholtz theory

WebEen helmholtzresonator is een akoestische resonator die bestaat uit een volume lucht (of ander gas) dat via een opening in een (prismatisch) kanaal (ook wel de hals of poort genoemd) in verbinding met de buitenlucht staat. Als de opening wordt getroffen door een geluidsgolf ontstaat er een veranderlijke overdruk aan de ingang van de hals. WebThe Theories of Helmholtz in the Work of Varèse. × Close Log In.
