Please answer the questions. Thank you. 1. Better temporal resolution means that we can perceptually track faster changes of: (choose one) [ envelope] [ fine structure ] [ pitch ] [ spectral splatter ] [ lateralization ] 2. Name at least two ways in which envelope changes appear in the speech signal as meaningful linguistic cues: ______________________ _________________________ 3. [ backward masking ] simultaneous masking ] [ forward masking ] has the most long-lasting effects. (choose one) 4. How is loudness adaptation for low-intensity sounds different than that for high-intensity sounds? 5. Voice pitch as measured by glottal vibration rate mainly corresponds to: (choose one) [ Envelope ] [ periodicity ] [ fine structure ] 6. Vowel advancement (place of articulation) corresponds mainly to: (choose one) [ Envelope ] [ periodicity ] [ fine structure ] 7. The “coincidence detection” model says that interaural timing differences are converted into a (choose one) [ spatial code ] [ spectral code ] [ timing code ] [ phase code ] 8. Sound localization in the vertical dimension is accomplished using what kind of cues? [ level cues ] [ spectral cues ] [ timing cues ] [ envelope cues ] 9. At a constant modulation depth, we are most sensitive to modulation rates in what range? (choose one) [ 2 – 4 Hz ] [ 200 – 400 Hz ] [ 2000 – 4000 Hz ] 10. Sketch the waveform of a sound that can be used to test forward masking. Label the noise and the tone. 11. Draw two sounds that differ in terms of amplitude modulation depth. 12. Briefly explain how level cues and timing cues complement each other for horizontal localization. 13. How do we know that forward masking is a peripheral in nature?
