WebA Helmholtz resonator is simply a box with a port on its front side to couple the enclosed volume of the airspace in the box to the air in the room. The depth of the enclosed airspace in the box behind the port and the width and depth of the port control the resonant frequency of the bass trap. Another form of helmholtz resonator is created ... WebDamit Pegelüberhöhungen (Raummoden) wirksam bedämpft werden, sollte ein Resonator idealerweise zwischen 300 und 500 Liter Volumen haben. Man kann mehrere davon …
