The speed of sound in dry air at 20 °C is 343 m/s and the lowestfrequency sound wave that the human ear can detect is approximately20 Hz. (a) What is the wavelength of such a soundwave?
The power output of a certain public address speaker is 2.1 W. Suppose it broadcasts equally in all directions. At what distance (in cm) from the speaker would the sound be barely audible (B -120 dB)? (Answer in 2 decibal places)
Sound with intensity larger than 120 dB appears painful to a person. A speaker
delivers 280 W of audio output. How close can the person get to the speaker
without feeling pain?

- Some studies suggest that the upper frequency limit of hearing is determined by the diameter of the eardrum. The wavelength of the sound wave and the diameter of the eardrum are approximately equal at this upper limit. If the relationship holds exactly, what is the diameter of the eardrum of a person capable of hearing 20 000 Hz? (Assume a body temperature of 37.0C.)arrow_forwardAc was held on an open field.

- High‑intensity focused ultrasound (HIFU) is one treatment for certain types of cancer. During the procedure, a narrow beam of high‑intensity ultrasound is focused on the tumor, raising its temperature to nearly 90∘C and killing it.
