9. Sound levels are measured by the logarithmic decibel scale, named after Alexander Graham Bell. The sound level, L, corresponding to an intensity of I, in watts per square metre, is し= 10 log-, where lo is the minimum intensity audible to the human ear. If amplified rock music has a loudness of 120 dB and ordinary conversation has a loudness of 50 dB, how many times louder than ordinary conversation is amplified rock music?

Using a frequency-measuring lab device, I am to map out the sound intensity level distribution (dB) in a room (both with & without music playing) to create a 5x5 grid of 25 data points. Using the following data table of sound intensity level β(dB) and corresponding intensity I(W/m2), I also need to find the intensity to the nearest order of magnitude for the points on my sound intensity level maps. Here is the data table: Intensity levelβ(dB) Intensity I(W/m2) Example/effect...

A decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, often sound level, power or intensity. It is given by: dB - 20 logx Where x is the ratio. Convert the following numbers to dB 1. x=01 dB- dB = 3. x 10 dB- 4. x=473 dB : 5.x=1000 dB= Problem 2 (10 points) Convert the following numbers in dBs to magnitudes (i.e. find x) . -55 dB -17 dB_ 4,...

East Coast Digital (ECD) produces high-quality audio and video equipment. One of the company’s most popular products is a high-definition personal video recorder (PVR) for use with digital television systems. Demand has increased rapidly for the PVR over the past three years, given the appeal to customers of being able to easily record programs while they watch live television, watch recorded programs while they record a different program, and save dozens of programs for future viewing on the unit’s large...
