A sound wave propagating in air has a frequency of 3.70 kHz. Calculate the change in wavelength when the wave, initially traveling in a region where T = 27.0°C, enters a region where T = 13.0°C.

The relationship between the number of decibles B and the intensity I in watts per square meteris denoted by the equation B = 10log(10^12 x I). If the intensity of a given sound is increased by a factor of 100, by how much does the number of decibels increase?

A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 5.83 104 Hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect?mm

A plane approaches you at 760 mi/h. It produces a sound at a frequency of 256 Hz. What frequency do you hear?  Let the speed of sound be 343 m/s, 1 mile = 1609.34 m, 1 hr = 3600 s

The speed of sound in air is 331 m/s at atmospheric pressure and 0 Celsius.  Suppose you put a electronic pinger in an air-tight glass jar and change the pressure  of the air inside by a factor  1.3,  while the volume, composition and temperature of the air remain the same.  What speed would you measure for the sound  inside the jar? Give your answer in m/s.

The speed of sound in a solid medium is 15 times greater than that in air. If the frequency of a wave in the solid is 61 kHz, then what is the wavelength? (The speed of sound in air is 344 m/s.)

The intensity of sound is measured on the decibel scale, dB. The equation dB=10logI represents the decibel level, where I is the ratio of the sound to the human hearing threshold.On a construction site, a large sheet of steel is dropped on the ground. The noise it makes is 100,000 times greater than the human hearing threshold. To the nearest whole number, what is the decibel value of the noise?

The speed of sound in an ideal gas (not air) is 750 m/s at -50°C. What is the speed of sound in the same gas at T = 55°C? The absolute zero temperature is -273.15°C. The speed of sound, cs(T = 55°C) =  Units

The intensity of a sound wave, as it strikes a circular ear drum, is 0.65 W/m2. The amount of energy carried in this wave is 6 × 10-6 J, and the sound lasts for one second. Part (a)  Calculate the radius of the ear drum, in meters.   Part (b)  If the sound wave travels at 326 m/s and has a wavelength of 1.1 m, calculate its frequency.

A sound wave in a solid has a frequency of 24.0 kHz and a wavelength of 0.333 m. What would be the wave speed, and how much faster is this speed than the speed of sound in air? (The speed of sound in air is 344 m/s.)
