A person has a hearing threshold 10 dB above normal at 100 Hz and 50 dB above normal at 4000 Hz. How much more intense must a 100-Hz tone be than a 4000-Hz tone if they are both barely audible to this person?
. A person stands directly in front of Iwo speakers that are emitting the same pure tone. The person then moves to one side until no sound is heard. At that point, the person is 7 in from one of the speakers and 7.2 in from the other. What is the frequency of the tone being emitted?
Dolphins make sounds in air and water. What is the ratio of the wavelength at a sound in air to its wavelength in seawater? Assume air temperature is 20.0°C.

Two identical columns, open at both ends, are in separate rooms. In room A, the temperature is T=20C and in room B, the temperature is T=25C . A speaker is attached to the end of each tube, causing the tubes to resonate at the fundamental frequency. Is the frequency the same for both tubes? Which has the higher frequency?
The ear canal resonates like a tube closed at one end. (See [link]Figure 17_03_HumEar[/link].) If ear canals range in length from 1.80 to 2.60 cm in an average population, what is the range of fundamental resonant frequencies? Take air temperature to be 37.0°C, which is the same as body temperature.
