Abstract (en)

[origin: WO2010018069A1] In a method for adjusting a Helmholtz resonator (10) which comprises at least one resonator volume (11) which is connected to a space (13) to be damped, along an axis (19) via a constriction (12) having an acoustic resistance, the acoustic resistance of the constriction (12) is changed in order to adjust the Helmholtz resonator (10).
