The direction of acoustic beam and angular width of mainlobe can be changed by properly amplitude-weighting, decreasing the frequency of impulsive signal and adjusting the interval of array elements.
The main correlational language cortex included left temporal lobe and bilateral inferior frontal gyrus.

It's better to select the minimum energy window to calculate RMS of sine wave by using the window DFT on the basis of the amplitude of sine wave DFT mainlobe.
