By the time of the midterm exam, students should be able to do the following:
2. Compute the frequency response and impulse response of a duct, or of a rectangular room (a,k).
3. Given a matrix frequency response representing a two-port system, calculate the one-port frequency response that results from constraints on any two of the inputs (a,b,e,m).
4. Compute the magnitude and phase response of a speaker/microphone pair given tonepip measurements at different frequencies (a,b,c).
5. Analyze an equivalent circuit to calculate the magnitude and phase response of a moving armature loudspeaker, electrostatic loudspeaker, electrodynamic microphone, or condenser microphone (a,b,d,g,m).
6. Create a desired microphone directivity pattern by scaling and adding omnidirectional and ﬁgure-eight patterns (a,b,e).
7. Calculate the perceptual loudness of a sound made up of spectrally distinct tones and noise bands (b,c,k,m).
8. Determine whether or not one simple sound (tone or noiseband) will perceptually mask another (b,e,h,m).
9. Estimate the pitch of a speech or musical signal using autocorrelation (a,b,e).
10. Use the correlogram method to estimate the pitches of two bandpass-ﬁltered harmonic signals played simultaneously (a).
