. A sound wave at the 7 decibel level of loudness has what intensity? If the amplitude of this wave were doubled, what would be the 1oudness in decibels? Explain how you would compute the combined loudness level of two sounds which are individually at B dB and β2 dB
Which of the following is NOT a property of sound waves? A. The speed of sound waves in air depends on the temperature of the air B. The pitch of a sound wave is closely related to its frequency C. The loudness of a sound wave is related to its amplitude and frequency D. Sound waves can travel through empty space

The principle of continuity states that for fluid flow to be continuous it must Select one: a. speed up in narrow regions of flow. b. slow down in wide regions of flow. c. both of these d. neither of these 3. Both a transverse wave and a longitudinal wave have Select one: a....
Much is still to be learned about the relationship between sound frequency and loudness. One way to study this relationship is to have listeners perform loudness judgments for tones of different frequences. For each listener, the output of these judgments is a number, measured in sones, that gives the loudness of the tone relative to the loudness of a reference tone. You have in front of you data from an experimental study in which 54 listeners were asked to perform...
13. One way to represent sounds is in terms of a sound spectrum, which plots magnitude (or power or amplitude) as a function of frequency. Another way to represent sound is to plot_ _ as a function of (a) time; frequency (b) time; pressure (c) pressure; time (d) none of the above 14. True or False. The auditory filter is, on a linear scale, wider at 1500 Hz than at 4000 Hz. 15. Imagine you hear a sound composed of...
Which of the following does the intensity of a sound wave not depend on? O The distance from the source of the sound. O The density of the medium in which the sound is traveling. O The cross-sectional area of whatever is receiving the sound. © The power output of the source of the sound. O The velocity of sound in the medium in which the sound is traveling. o The amplitude of the sound produced by the source.
