Summary[edit]

Description
English: In a silent room, there are two stereo speakers facing one another, equidistant from a microphone. If each speaker is outputting a pure tone at 1000Hz with 40dB SPL amplitude and their periods are such that there is perfect constructive interference at the microphone, what frequency and amplitude will the microphone record?
