System transfer functions & Head-related transfer functions (HRTFs). Dr. Duck O. Kim. Salamanca, Spain May, 2010. The response of a linear system to any stimulus Is totally predicted by the system’s impulse response, h(t) , or the transfer function, H(f).

System transfer functions & Head-related transfer functions (HRTFs) Dr. Duck O. Kim Salamanca, Spain May, 2010
The response of a linear system to any stimulus Is totally predicted by the system’s impulse response, h(t), or the transfer function, H(f). H(f) = Fourier transform of h(t)
linear system: h(t); H(f) input output x(t) y(t) X(f) Y(f) h(t): impulse response of the system; H(f): transfer function of the system; H(f) = Fourier transform of h(t) y(t) = x(t) convolved with h(t); Y(f) = X(f) ∙ H(f)

When HRTFs are obtained, one can simulate an external sound source located at any specified position. virtual auditory space (VAS)method Y(f) = X(f) ∙ H(f) Dr. Kuwada will illustrate neural responses obtained with the VAS method.
