Abstract (en)

[origin: US2003029669A1] The creation of sounds by musical instruments or sound reproduction systems is not perfect, but acoustic dissonances inherent in the production of sound generators can be corrected. The present method uses open volumes, such as a glass, possibly provided with a cutoff, a fragmentation creating at least one opening. This object placed close to or on a sound generator frees additional sound waves to harmonise with the sound generator by means of mechanical coupling or an air sound link due to the volume of the resonator and its fragmentation. A device made of a material with a Shore hardness of more than 60 makes it possible via its foot fixed to a piano to transmit mechanical sound vibrations. Method and device constitute an effective improvement in the reproduction and creation of sounds.
