This is because the ear, as we will see later, appears to be less sensitive to the phase of the individual frequency compared to the relative amplitudes. Because of this, often only the amplitude of the frequency components are plotted in the spectrum and, in order to handle the range of possible amplitudes and because of the way we perceive sound, the amplitudes are usually plotted as decibels. 24 in Chapter 4 shows the waveform and spectrum plotted in this fashion for middle C played on a clarinet and tenor saxophone.

This happens because the energy in the travelling wave must always exist at a pressure node carried in the velocity component and at a velocity node the energy is carried in the pressure component. 8 Standing waves at other boundaries There are two other pairs of boundary arrangements which can support standing waves. 32, is the case of a bounded to unbounded boundary at both ends. An example would be a tube or pipe which is open at both ends. 32. 31 The pressure components of a standing wave between two bound–unbound boundaries.

This results in enhanced reflection from or diffraction around the object at particular wavelengths. The precise nature of these effects depends on the interaction between the front and back of the scattering object and so will be significantly affected by its shape. Thus the variation in scattering will be different for a sphere compared to rectangular plate. As the sum of energy diffracted around the object and the scattered energy must be constant, the reflection and diffraction responses will be complementary.
