3. In complex tones (that are composed of many harmonics), the perceived pitch usually corresponds to the pitch of the fundamental frequency (the lowest frequency in the harmonic series). The set of harmonics can sound like the pitch of the fundamental even when the fundamental is not physically present (the case of the missing fundamental). For each harmonic series, what single frequency should have the same perceived pitch? a. 1000 + 2000 + 3000 + 4000 Hz b. 2000 + 3000 + 4000 + 5000 Hz C. 1000 + 1500 Hz d. 2000 + 2500 + 3000 Hz 4. The speed of sound in air is ~350 meters per second: slow enough that we can detect the difference in the time when a sound arrives at the two ears. Suppose the separation between the ears is 0.2 meters and a sound comes directly from the left side. a. How much sooner (in milliseconds) will the sound arrive in the left ear than the right ear? (Note: time = ear separation/ speed of sound * 1000 milliseconds.) b. Suppose a sound arrives at the left ear 0.5 milliseconds (ms) sooner than the right ear. If the frequency is 1000 Hz, how many cycles behind is the sound in the right ear? (Note: if there are 1000 cycles per second then there is 1 cycle per millisecond.) c. Why is this a problem for deciding whether the sound is coming from the right or left?
