- Sound is more effectively transmitted into a stethoscope by direct contact rather than through the air, and it is further intensified by being concentrated on the smaller area of the eardrum. It is reasonable to assume that sound is transmitted into a stethoscope 100 times as effectively compared with transmission though the air. What, then, is the gain in decibels produced by a stethoscope that has a sound gathering area of 15.0 cm2, and concentrates the sound onto two eardrums with a total area of 0.900 cm2 with an efficiency of 40.0% ?arrow_forwardThe sound level 8.25 m from a loudspeaker, placed in the open, is 115 dB. What is the acoustic power output (W) of the speaker, assuming it radiates equally in all directions?arrow_forwardAn FM communication system has a sensitivity of 4 kHz/V. How much deviation (in Hz) does it produce with a sine wave input of 19.66 Vpeak at a frequency of 4.8 kHz?arrow_forward
- A 50 cm long wire fixed at both ends vibrates with afundamental frequency fo when the tension T is 50 N. If thetension is increased to 60 N, the fundamental frequencyincreases by 5 Hz. Determine the mass of the wire and thefrequency fo.arrow_forwardTwo identical loudspeakers 10.0 m apart are driven by the same oscillator with a frequency of f = 21.5 Hz (as shown) in an area where the speed of sound is 344 m/s. (a) Show that a receiver at point A records a minimum in sound intensity from the two speakers. (b) If the receiver is moved in theplane of the speakers, show that the path it should take so that the intensity remains at a minimum is along the hyperbola 9x2 - 16y2 = 144 (as shown). (c) Can the receiver remain at a minimum and move very far away from the two sources? If so, determine the limiting form of the path it must take. If not, explain how far it can go.arrow_forwardA wave of wavelength 0.60cm is produced in air and it travels at a speed of 300m/s. Will it be audible?arrow_forward
- A tuning fork with a frequency of 256 Hz is held above a closed-air column while the column igradually increased in length. At what lengths for this air column would the first 4 resonant pointsbe found, if the speed of sound is 330 m/s?arrow_forwardWhat is the length of the shortest pipe open at both ends that will have a fundamental frequency of 0.060 kHz on a day when the speed of sound is 344 m/s?arrow_forwardA sound wave travelling in a dense medium has a frequency of 20 KHz and a wavelength of 40 cm. What would be the speed of this waveform? Also, as compared to the sound wave travelling in air, how much faster this wave is travelling?arrow_forward
- Find the ratio of the intensities of sound waves if one is 8 dB louder than the other.arrow_forwardA microphone receiving a pure sound tone feeds an oscilloscope, producing a wave on its screen. If the sound intensity is originally 2.00×10-5 W/m2, but is turned up until the amplitude increases by 30.0%, what is the new intensity?arrow_forwardWhat is the first overtone frequency (the next frequency above the fundamental) for an organ pipe 2.00 m in length, closed at one end? Speed of sound in air is 340 m/s.arrow_forward
