A noise has an intensity of 2.4×10-8 W/m2. If the threshold of human hearing is I0 = 1.0×10-12 W/m2, calculate the sound intensity level in dB. Use two digits of precision for your answer.
Use the data in Table 3 to make this plot. That is plot I, on the -axis vs. (1/d^2), on the x-axis. Then draw a best fit line throught the data points.
Learning Goal: To learn the properties of logarithms and how to manipulate them when solving sound problems. The intensity of sound is the power of the sound waves divided by the area on which they are incident. Intensity is measured in watts per square meter, or W/m². The human ear can detect a remarkable range of sound intensities. The quietest sound that we can hear has an intensity of 10-12 W/m², and we begin to feel pain when the intensity reaches 1 W/m². Since the intensities that matter to people in everyday life cover a range of 12 orders of magnitude, intensities are usually converted to a logarithmic scale called the sound intensity level 3, which is measured in decibels (dB). For a given sound intensity I, B is found from the equation B = (10 dB) log Io where Io = 1.0 × 10-¹² W/m². The logarithm of x, written log(x), tells you the power to which you would raise 10 to get x. So, if y = log(x), then x = 10%. It is easy to take the logarithm of a number such as 10², because you…

The formula for measuring sound intensity in decibels is defined by the equation D = 10 log(I/I0), where I is the intensity of the sound in watts per square meter and I0 = 10-12 is the lowest level of sound that the average person can hear. How many decibels are emitted from a jet plane with a sound intensity of 8.3 x 102 watts per square meter?
We use ultrasound to measure the diameter of a cuvette filled with water and obtain a value of 2.3 cm. For an object made of an unknown substance but having the same diameter, the ultrasound measurement yields a diameter of 1.5 cm. If the speed of sound of water is 1530 m/s, how many m/s is the speed of sound in the given substance? Speed of sound [m/s)
