Another way of illustrating the increasing dominance of the new noise component is shown in Fig. 18. This figure shows
the noise spectra from 601 to 901. Clearly,in this figure,the peak of the noise spectra increases in intensity and shifts to a
lower frequency as inlet angle increases. The shape of the noise spectrum becomes increasingly different from that of the
fine-scale turbulence noise. It is to be noted that the new peak in the noise spectra is not broadband shock cell noise . The
new peak decreases in frequency as inlet angle increases. This is opposite to the behavior of broadband shock cell noise,
which increases in frequency as inlet angle increases(see Fig. 7). In fact,after examining all the noise spectra,it is our
conclusion that there is no evidence of broadband shock cell noise in the angular sector 601-1501. However,this does not
mean that broadband shock cell noise is not generated. The noise is simply buried under more dominant noise components
