A method of improving the modal resonance frequency distribution of a panel ( 2 ) for a distribution resonant mode bending wave acoustic device involves analysing the distribution of the modal resonance frequencies of the panel, identifying a modal resonance frequency that is non-uniformly spaced relative to adjacent modal resonance frequencies, identifying a location on said panel that exhibits anti-nodal behaviour at said modal resonance frequency and changing the local impedance to bending wave vibration at said location ( 6 ). The method has particular application to distributed mode loudspeakers ( 1 ).
