George M. Rodgers MD, PhD,Christopher M. Lehman MDard varies from 12 mm (bass) at the bottom to 2.5 mm at the top (treble). The outer surface of the soundboard is covered with a sheet of veneer (1 mm thickness) in spruce or in a precious species, to prevent cracking and warping. The soundboard of variable section should be able to support the high

The most appropriate technology for a specific musical instrument is guided by the selection of the correct process and material characterized by some mechanical parameters such as the maximum a

If we make reference to how air column is excited by means of vibrating reed, the following classification of wind instruments can be proposed: mechanical reed instruments, lip valve instruments and air jet inst

Sterling T. Bennett MD, MSby a detailed discussion of the concept of entropy and entropy production. While the balance laws are universal for any continuous medium, the particular behavior of the material of interest must be described by an extra set of material-specific equations. These equations relating, for example, the
