Additionally, for part 2 measure the frequency of 3 items using the spectrum analyzer (examples: a musical instrument playing a note, the hum of the lights in the basement, the seatbelt reminder tone, the fundamental frequency of the first note of your favorite song, the sound of the hand signal at the crosswalk/traffic light, the whistle of your spouse’s or room-mate’s nose when they snore) and make a table. Try to make it something tonal that you measure so you can pick out a single tone. White noise spectrum, remember, is equal level per frequency so it won’t have any one particular frequency that jumps out or gives it a pitch. Try to measure sounds that are tonal or have a pitch for this part. Find and use 3 distinct sounds/frequencies.
Calculate the wavelength for the lowest frequency you’ve measured for those three sounds. If there are multiple peaks on the spectrum, use the fundamental or lowest frequency. Again, it might fluctuate a little so you may have to pick the frequency that it seems to hover around.
