Choosing the sound of the buttons being pressed on a calculator, I imagined the sound of a student in class, during a math test. Of course, not a math class at Pitt, because there is rarely a math class at Pitt where a calculator can be used on an exam. Anyway, I picture students in a classroom, maybe a big lecture hall. Someone is typing away on their calculator, and I imagine big numbers, based on the constant button pressing. Perhaps the person is multiplying numbers with many decimals places.
I can hear, well in my head I imagine, adding noises and sounds that would be also be heard during a test, because of course silence is never a thing. There is the sound of erasers being abused, the sound of the cough of the guy three rows over, the sound of a pencil being tapped against the table. Other sounds could be the of chalk as the teacher writes the time remaining on the black board, or of the sniff of the girl sitting to the right, or of papers flipping, or the idiot who never turned off their cell phone alarm, disrupting everyone. There are so many insignificant sounds involved in a test, or math test, that I can think of, including the sound of a calculator.
There are other sound on the collection list that could be included in this, like the sound of a door closing, or of a fan going off on the ceiling of the room, among others. There are so many sounds that could be added to create the scene and make things interesting, revolving around the sound of the calculator and layering different things among the “silence” of an exam.
