For example, the velocity of a Lamb-like wave in a thin cylinder will depend slightly on the radius of the cylinder and on whether the wave is traveling along the axis or round the circumference. Another question is what completely different acoustical behaviors and wave modes may be present in the real geometry of the part.

In a free-standing resonator structure air is used to separate the resonator from the substrate/surrounding. The structure of a free-standing resonator is based on some typical manufacturing steps used in micro-electromechanical systems MEMS. A schematic cross-section of the SMR structure with a one-sided acoustic mirror
A music download is the digital transfer of music via the Internet into a device capable of decoding and playing it, such as a personal computer, portable media player, MP3 player or smartphone. This term encompasses both legal downloads and downloads of copyrighted material without permission or legal payment.
A sine, square, and sawtooth wave at 440 Hz A composite waveform that is shaped like a teardrop. A waveform generated by a synthesizer In electronics , acoustics , and related fields, the waveform of a signal is the shape of its graph as a function of time, independent of its time and magnitude scales and of any displacement in time.

MUSIC II “had four-voice polyphony and was capable of generating sixteen wave shapes via the introduction of a wavetable oscillator.” [1] Hal Chamberlin discussed wavetable synthesis in Byte's September 1977 issue. [2] Wolfgang Palm of Palm Products GmbH (PPG) developed his version in the late 1970s [3] and published it in 1979. [4]
The NFL hit Dallas Cowboys wide receiver CeeDee Lamb with a $10,300 fine on Saturday for his wave after scoring the game-winning touchdown in overtime last week against the New England Patriots.
