After years of being alone and never getting a single phone call, Daniel understandably forgets to shut off his cell phone in class. One miraculous day, he finally receives a call and accidentally allows the ringer to emit sound waves uniformly in all directions. At a distance of 13.0 m. from the source, Mr. O''Hara's sensitive ears observe the intensity level to be 94.0 dB. What is the total acoustic power output of the cell phone speaker, in watts?
Going down the road at 65 miles per hour on a 86.0 °F summer day, Bari heard a siren approaching. Bari knows that a police siren's frequency is 1280.0 Hz, but it didn't sound like that. Bari pulled over a lane, without slowing down, after seeing the flashing lights of the police car coming up from behind, and the police passed going 25 miles per hour faster than Bari was going. (1 mile = 1.60 km) a) what was the speed of sound on that warm summer day? b) How fast, in m/s, was the police car going? c) What frequency did Bari hear from the siren before the police car passed? d) What frequency did Bari hear from the siren after the police care had passed?
An observer is riding a bike with a speed of 5 m/s. The ice cream van emitting a sound with anatural frequency of 600 Hz is coming up from behind the cyclist with a speed of 25 m/s.The siren making the sound is inside the cabin with the ice cream vendor.a) What is the frequency of the sound heard by the ice cream vendor inside the vehicle?b) What is the wavelength of the sound waves as detected by the ice cream vendor inside thevehicle?c) What is the frequency of the sound heard by the cyclist?d) What is the wavelength of the sound waves as detected by the cyclist?
A sound wave arriving at your ear is transferred to the fluid in the cochlea. If the intensity in the fluid is 0.410 times that in air and the frequency is the same as for the wave in air, what will be the ratio of the pressure amplitude of the wave in air to that in the fluid? Approximate the fluid as having the same values of density and speed of sound as water. Speed of sound in dry air (20.0°C, 1.00 atm) is 343 m/s, density of dry air (at STP) is 1.29 kg/m3, density of water is 1000 kg/m3, and speed of sound in water is 1493 m/s.

Hassan is driving his truck with a velocity of 18m/s towards a mountain. Kevin who is riding in the truck sounds a horn. The sound reflects from the cliff and is heard by Hassan and Kevin on the truck. What is the change in frequency in hertz if the horn had an initial wavelength of )=0.101 m? The temperature that day was 35 degrees celsius. (Speed of sound = 331+0.6 T(in celsius)). Please give your answer as a whole number.

Dolphins of the open ocean are classified as Type II Odontocetes (toothed whales). These animals use ultrasonic "clicks" with a frequency of about 55 kHz to navigate and find prey. Suppose a dolphin sends out a series of clicks that are reflected back from the bottom of the ocean 90 m below. How much time elapses before the dolphin hears the echoes of the clicks? (The speed of sound in seawater is approximately 1530 m/s.) What is the wavelength of 55 kHz sound in the ocean?
