Frequency Representations and the possibility of free spacing. Wavelets can be placed arbitrarily in a time series at any place, and therefore differ from a Fourier Transform which always needs to be performed between the two boundaries of the time series. Therefore Wavelets may have any frequency with arbitrary precision,缓和 发表于 2025-3-29 07:30:20
Embedding Representationstures. As the slavery principle, where one subsystem forces others to vibrate with its eigenfrequencies of the other holds for the quasi-steady state of the sound to most extend, the initial transient is clearly the struggling between the two subsystems until the slaving has been achieved.Amendment 发表于 2025-3-29 11:42:11
Applications to Musical Instrumentse or instrument building (Bader & Hansen 2008). It has been applied to many instruments. With guitars it could be found, that the coupling of bending and in-plane waves in the guitar body plays a crucial role in the sound (Bader 2005a) (Bader 2005b). Also the need to build the guitar back plate undeADORN 发表于 2025-3-29 16:06:55

Musical Instrumentsng the first modern investigator of the violin. He was the first to introduce the idea of the sound post to change a violin from a dipole to a monopole source with much larger radiation in the low frequency range. Indeed to date the violin may be the instrument which has been investigated most often减至最低 发表于 2025-3-30 01:57:27

Examples of Impulse Pattern Formulation ribs, and inclosed air. All of them are interacting and driven by impulses. The string is ‘knocking’ on the top plate periodically. If the string is displaced in a trapezoid manner and then set free, the trapezoid motion is travelling cyclically around the string. At the bridge point the changing a
