Our question for this assignment was “how does the size of a room affect the decibel level of a sound wave?” We started to work don a question and hypothesis knowing that waves can be different in wavelengths and frequencies. This would mean we would need to keep all the variables like the note we were playing, and the volume at which we would play the note the same. We came up with the question that is written in the first sentence, and started working on how we would test it. We decided that to test this we could have an amplifier set to a specific volume to play a specific sound and check the decibel level in each corner of the room. This would show exactly how the sound waves would be affected by the size of the room. We started by testing a large room of 624 square feet. Then we tested a smaller room of 52 sq ft. After doing these tests we analyzed the data that was collected. The data showed that a smaller room with all the walls in close proximity kept the decibel level higher, while a larger room with walls that had a greater distance from each other distorted the sound to a lower decibel. In the bigger room when you would move around the sound of the note would be different in all places, it was not consistent. In the smaller room however, the walls where closer and when you moved around the move the note would sound the same for the most part.
