Two people hear a tornado siren, but one listener is 44.1 times farther away from the source of the sound than the other. What is the intensity level (in dB) at the farther listener relative to the other listener?

A weather emergency siren is mounted on a tower, 153 meters above the ground. On one hand, you would like to make the siren very loud so that it will warn as many people as possible. On the other hand, safety regulations prohibit you from exceeding an intensity level of 111 dB for workers standing on the ground directly below the siren. Assuming that the sound is uniformly emitted, what is the maximum power that the siren can put out?...

You hear the siren on an ambulance off in the distance. If the pitch is lower than it would be normally, what can you conclude about the motion of the ambulance? a. the ambulance is moving away from you. b. the ambulance is moving towards you. c. the ambulance is not moving at all relative to you. d. we cannot determine if the ambulance is moving without also knowing the wavelength of the sound waves.

A weather emergency siren is mounted on a tower, 153 meters above the ground. On one hand, you would like to make the siren very loud so that it will warn as many people as possible. On the other hand, safety regulations prohibit you from exceeding an intensity level of 101 dB for workers standing on the ground directly below the siren. Assuming that the sound is uniformly emitted, what is the maximum power that the siren can put out?...

A weather emergency siren is mounted on a tower, 177 m above the ground. On one hand, it would be a good idea to make the siren very loud so that it will warn as many people as possible. On the other hand, safety regulations prohibit the siren from exceeding an intensity level of 101 dB for workers standing on the ground directly below the siren. Assuming that the sound is uniformly emitted, what is the maximum power that the...

You are jogging along a straight road one day at constant velocity vo when you hear the siren of an ambulance approaching from behind. The frequency you hear is f1 = 756 Hz. You stop to take a break and the frequency you hear changes to f2 = 765 Hz. The ambulance then overtakes you and speeds away, and the frequency you hear is f3 = 680 Hz. The speed of sound in air is vsound = 340 m/s and...

One way of measuring the frequency of a sound is to make measurements of the interference pattern that is created when the sound is produced by two sources. You find that for two sources, the sound is loudest when you are equidistant from the sources. You then determine that there is a minimum in intensity when you are 3.1 m farther from one source than the other. What is the frequency of the source? Use the speed of sound of...

You're driving your new Corvette convertible and can clearly hear other cars driving nearby. One of these cars honks their horn and your car, with its apps and sensors, displays the horn sound as 760Hz. Your Corvette also registers the car as a Mustang with a car horn of 795Hz. You are stopped at a stop light when their horn blares. Another of your Corvette apps measures the air temperature to be 26°C. a) What is the speed of sound...

Two identical loudspeakers are some distance apart. A person stands 5.80 m from one speaker and 3.10 m from the other. What is the lowest frequency at which the person will hear destructive interference? The speed of sound in air is 340 m/s.
