One way to monitor global warming is to measure the average temperature of the ocean. Researchers are doing this by measuring the time it takes sound pulses to travel underwater over large distances. At a depth of 1000 m, where ocean temperatures hold steady near 4∘C, the average sound speed is 1480m/s. It's known from laboratory measurements that the sound speed increases 4.0m/s for every 1.0∘C increase in temperature. In one experiment, where sounds generated near California are detected in the South Pacific, the sound waves travel 8300 km .If the smallest time change that can be reliably detected is 1.0 s, what is the smallest change in average temperature that can be measured?
In this problem take the speed of sound to be 348 m/s.
A. How fast, in meters per second, does an observer need to approach a stationary sound source in order to observe a 3.1 % increase in the emitted frequency?
Sound level B in decibels is defined as
()
B = 10 log
1 x 10-12 w/m². The decibel
where Io
scale intensity for busy traffic is 83 dB. Two
people having a loud conversation have a deci-
bel intensity of 70 dB.
What is the approximate combined sound
intensity?
Answer in units of W/m2.
