The source sent an ultrasonic signal of the frequency of 5 MHz and received two echo-signals with a delay of 60 ms between them. The first echo-signal returned after 40 ms. What is the thickness of the organ from which the signal was reflected if the reflection occurred from opposite sides of the organ? What is the absorption coefficient if the intensities of the echo-signals differ by 1120 times? The speed of the wave is 1450 m / s.

In each of the four scenarios shown in the images, a large bat lets out a short burst of ultrasonic sound, which a smaller bat hears a moment later. If the large bat flies at 2.320 m/s and the small bat flies at 13.80 m/s, order the frequencies that the smaller bat detects in the four scenarios from highest to lowest. Assume that the speed of sound is 343.0 m/s. Highest frequency A D B. A B C Lowest frequency Answer Bank In Scenario C, part of the large bat's signal reflects off the small bat and returns to the large bat, warning it of the smaller bat's presence. If the initial signal has a frequency of 66.70 kHz, what return frequency fr will the large bat detect? Calculate the final frequency to four significant figures. fr Incorrect kHz Ꭰ

When two sources located at different positions produce the same pure tone, the human ear will often hear one sound that is equal to the sum of the individual tones. Since the sources are at different locations, they will have different phase angles p. If two speakers located at different positions produce pure tones 元 P, =A, sin (2uft + 1) and P, = A2 sin (2nft + dp2) , where - s41,.427, then the resulting tone heard by a listener can be written as P = A sin (2nft + 4), where A, sin 4, + A, sin p2 4 = arctan (A, cos 4, + A, cos 42)² + (A, sin d, + A2 sin 2) 2 .

Calculative questlon: 15.You and you team are asked to determine the hearing safety parameters for a loud experiment. Since the sound will persist for only a short time, the allowed intensity level that will not result in permanent hearing damage is 135 dB. The experiment consists of a single source with power output of 550 W that projects sound isotropically (i.e., uniformly in all directions) a) At what distance should you set the safety perimeter (i.e., the radius of a sphere in meters) centered at the source? b) Where should you set the perimeter is the power of the source doubles?
Two loud speakers are 3m apart. A person is listening to a single pitch at 680Hz. Theperson is along the back wall, which is reasonably far, what are two directions from the center ofthe speakers where the person would expect to have the music loud? Repeat for two directionsthat are quiet.The person is now standing at the location that is 4m directly in front of one of thespeakers. Determine whether that position is loud, quiet or somewhere between the twoextremes. Explain. Use a diagram to help. [Note: Do not assume the person is far away.Comment on why that makes a difference.]
