- Pr5. Two identical loudspeakers are located at points (-10,0,0) and (0,0, 10) of our coor- dinate system, where the numbers in the brac- kets correspond to the (r, y, z) coordinates of the points, expressed in meters. The loudspeakers are driven by the same oscillator with a frequ- ency of 170 Hz. The speed of sound in air can be considered 340 m/s. a) Give the coordinates of those points loca- ted on the positive r axis where the sound waves coming from the two loudspeakers interfere con- structively. b) A receiver is started to move slowly from the origin (0,0,0) along a path lying in the r-y plane so that it receives constant sound intensity throughout its slow motion. What is the shape of the path the receiver should take?Help with the following questionA violin is tuned by adjusting the tension in the strings. Brian’s A string is tuned to a slightly lower frequency than Jennifer’s, which is correctly tuned to 441.0 Hz. What is the frequency of Brian’s string if beats of 1.00 Hz are heard when the two bow the strings together?
- .Negative decibels? Our discussion of decibels did not mention that they can be negative. On the Redmond, Washington campus of Microsoft is an anechoic chamber that, according to Guinness World Records, is the quietest place in the world. It measures –20.3 decibels. a. What is the relative intensity of a sound measuring –1 decibels? Round your answer to one decimal place. b. What is the relative intensity of a sound measuring –10 decibels? Round your answer to one decimal place. c. What is the relative intensity of Microsoft's anechoic chamber? Round your answer to three decimal places. d. Is it possible for the relative intensity to actually be zero?3 rces The sound of normal breathing is not very loud, with an intensity of about 11 dB at a distance of 1 m away from the face of the breather. Note that in this problem sound intensity in decibels is denoted 3; intensity in W/m² is denoted I View Available Hint(s) distance Ddetect in meters. Ddetect = 3.16 m Submit Previous Answers ✓ Correct Part B In general, if a sound has intensity of 3 dB at 1 m from the source, at what distance de from the source would the decibel level decrease to 0 dB? Since the limit of hearing is 0 dB this would mean you could no longer hear it. Express the distance in terms of B. Be careful about your signs!
