How does our sensitivity to hearing different frequencies change with intensity? Compare a 1000 Hz sound at 60 dB (conversation level) to a 5000 Hz sound at 32 dB (also conversation level)
The area of a typical eardrum is about 5.0x10−5 m2. What is the sound power (energy per second) incident on the eardrum at the threshold of hearing? What is the sound power (energy per second) incident on the eardrum at the threshold for pain?
A man and a dog observe in the distance a loud nuclear explosion producing a sound having an effective power of 1.6 kW. The man does not hear the sound of the explosion while the dog can hear it. Knowing that humans can hear a sound from 0 dB and the dog can hear a sound from -6 dB, we want to estimate how far away the explosion is. We use the usual approximations and assume that the sound travels over the surface of a sphere. Keep in mind the speed of sound is 343 m/s. In between ? km and ? km do the man and the dog are from the explosion ?
Calculate the increase in sound level resulting from using an ear trumpet to aid in hearing. Take the effective area of the trumpet to be 900 cm2, the eardrum’s area to be 0.500 cm2, and assume the trumpet is 5.00% efficient in routing the sound to the eardrum.
Loudspeakers can produce intense sounds with surprisingly small energy input in spite of their low efficiencies. Calculate the power input needed to produce a 90.0-dB sound intensity level for a 12.0-cmdiameter speaker that has an efficiency of 1.00%. (This value is the sound intensity level right at the speaker.)
As it approaches a boy standing on the road, an ambulance traveling at 100 km/hr blows its siren. Determine the frequency of the sound waves reaching the boy if the siren has a frequency of 460 Hz and the temperature of the air is at 0° C after it has passed the boy.
Light travels faster than sound. During a thunderstorm, an approximately 5s time lapse between observing the lighting and hearing the thunder. Calculate approximately howfar in meters was the lightning flash?
With the advent of tiny, powerful rare earth magnets, and improvements in rechargeable battery and wireless technologies, wireless earbuds, like Apple’s AirPods (see the photo), enhance the enjoyment of listening to music, movies, and podcasts, and allow handsfree conversation. However, since the earbuds focus sound waves directly into the auditory canal at close distances, care must be taken to protect the eardrum from long-term exposure to high volumes (intensity levels). Hearing experts recommend listening at a maximum intensity level of 85 dB for no more than 8.0 hours a day. Assuming a constant intensity level of 85 dB, how much energy in mJ (1000 mJ=1Joule) does the eardrum absorb during 6.76 hours? Take the area of the eardrum to be 0.65 cm2 (1cm2 = 1x10-4 m2).
Estimate the force exerted on your eardrum due to the water when you are swimming at the bottom of a pool that is 5.0 m deep.
Loudspeakers can produce intense sounds with surprisingly small energy input in spite of their low efficiencies. Calculate the power input needed (in W) to produce a 85.1 dB sound intensity level for a 15.5 cm diameter speaker that has an efficiency of 2.56%. (This value is the sound intensity level right at the speaker.)
Calculate the amount ofinward forceon youreardrum at the bottom of a 5mdeep pool and compare it to the inward force on youreardrum at atmosphericpressure. An eardrum has an approximate diameter of10mm.(you should have twoanswers and compare them).
