- What sound intensity level corresponds to a sound intensity of 6.96 x 10-3 W / m2If a gas tap is turned on for a few seconds, someone a couple of meters away will hear the gas escaping long before she smells it. What does this indicate about the speed of sound and the speed at which molecules diffuse through the sound-carrying medium?Ultrasound probes can resolve structural details with sizes approximately equal to the wavelength of the ultrasound waves themselves. What is the size of the smallest feature observable in human tissue when examined with 14-MHz ultrasound? The speed of sound in human tissue is 1,540 m/s.
- The figure has a moving sound source S, that is emitting a frequency. There are 4 stationary sound detectors. I want to rank the detectors according to the frequency of the sound they detect from S from greatest to first. and Why? I got 3,1,4,2.. My reason being that has it travels forward the frequency is at its highest, nearest and in front of it, then fades out. But I'm not sure I'm correct. Could you explain this to me? Thank you.A sound of frequency 5 Hz : (a) is of very short wavelength (b) is inaudible (c) moves very slowly (d) is very loudWhich statement about how the pitch of a sound is determined is accurate? neuromast cells in different parts of the middle ear respond to different sound frequencies sensory neurons in the tympanic membrane fire action potentials at the appropriate frequency regions of the basilar membrane with shorter, stiffer fibers vibrate more with high frequencies sensory neurons lining the inner walls of the cochlea send action potentials at the same frequency which they vibrate
- In a pig-calling contest, a caller produces a sound with an intensity level of 107 dB. How many such callers would be required to reach the pain level of 120 dB?If a tree falls in a forest and no one is there to hear it, do you think it made a sound? Why or why not?One physics teacher lecturing produces a sound intensity level of 61 dB . It's a scary thought, but predict what the sound intensity of 100 physics teachers talking simultaneously would be.
- Elephants and whales are known to use infrasound to communicate over very large distances. What are the advantages of infrasound for long distance communication?An observer hears a sound from a vehicle that is parked. Then, the vehicle starts moving toward her. What will happen to the frequency and wavelength of the waves when the vehicle starts moving toward her? Your answer: The frequency and wavelength will both increase. The frequency and wavelength will both decrease. The frequency will increase and the wavelength will decrease. The frequency will decrease and the wavelength will increase.Give a detailed and specific description of the human perception of Loudness.
