In the figure, a sound of wavelength A is emitted isotropically by point source S. Sound ray 1 extends directly to detector D, at distance L. Sound ray 2 extends to D viaa reflection (effectively a "bouncing") of the sound at a flat surface. The reflection occurs on a perpendicular bisector to the SD line, at distance d from the line. Assumethat the reflection shifts the sound wave by 1/2 as discussed in the previous chapter. For what least value of d (other than zero) do the direct sound and the reflectedsound arrive at D (a) exactly out of phase and (b) exactly in phase? Please state your answers in terms of the given variables.Ray 2Ray 1L2

Two identical speakers are initially equal distancesfrom a listener . Thelistener hears a sound maximum (constructiveinterference). When the upper speaker is moved backby a distance d = 2 m, the listener hears a soundminimum (destructive interference). What is thelongest wavelength the soundwaves could have?

Consider an omnidirectional mobile robot with a ring of twelve ultrasonic sensors (each with an opening angle of 30o) that are fired sequentially. Calculate the slowest scan rate in Hz (i.e. number of full 360o scans per second) if the furthest object of interest is 4m away at any given time. Give your answer to 2 decimal places. Assume the speed of sound in air is 343 m/s.
(a) To appreciate the human ear’s twelve order of magnitude (1012) span from barely audible to the pain threshold, consider the following. Suppose an equivalently dynamic instrument were designed to measure distances. Taking the lower limit of the instrument to be 1.00 mm, what would be the largest distance measurable? (b) To provide a perspective for the human ear’s frequency sensitivity range (audible frequency extremes differ by 103 ), consider a speedometer with a similar speed range. If the speedometer’s maximum speed reading is 90.0 mi/h, what is the smallest finite speed that it could register?
Speaker 1 is at x = 0 and speaker 2 is to the right and facing it at x = 8 m. The speakers are to the same amplifier, which plays a tone at 327 Hz.

What is the resultant sound level when an 81-dB sound and an 87-dB sound are heard simultaneously? This question is in the library, but, some of the answers is not visible. Some of the values are not viewable. I, and anyone else who wants to use it, need a copy that is fully readable. I should not have to "use up" my questions getting clean images like this.
Speaker 1 is at x = 0 and speaker 2 is to the right and facing it at x = 3 m. The speakers are to the same amplifier, which plays a tone of unknown frequency. If the first point of destructive interference is 0.18 m to the left of the center, find the frequency in Hz. The speed of sound is 345 m/s. connected continuous f = Hz
