It demonstrates that at least two Eigenfrequenzen (= natural frequencies) of the excited wine glasses with frequencies in Hz of \"F1\" and \"F2\" (with F2) will generate complex tones with frequencies in Hz of \"F2+F1\" and \"F2-F1\" - which is a typical characteristic of multiphonic sounds known from woodwind instruments. Based on the analysis of the decay kinetics of the Eigenfrequenzen and the complex tones after a hit-excitation of the wine glass, the hypothesis has been developed that the oscillations F1 and F2 build a power-profile which can be mathematically described as a multiplication of the amplitude-values of both oscillations and that this power-profile is the driving force to generate oscillations of some areas of the walls of the bowl of the wine glasses with the frequencies \"F2-F1\" and \"F2+F1\".\u003c\/p\u003e","brand":"Grin Verlag","offers":[{"title":"Paperback","offer_id":45568459604119,"sku":"9783346867957","price":2143.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9783346867957.webp?v=1768603726","url":"https:\/\/atlanticbooks.com\/products\/the-origin-of-complex-tones-multiphonic-sounds-generated-with-wine-glasses-and-woodwind-instruments-9783346867957","provider":"Atlantic Books","version":"1.0","type":"link"}
