    Phase Cancellation
    Undesirable dips and peaks in frequency response caused by mixing the outputs of two microphones which are picking up the same sound but with different arrival times. For example, this can occur when two microphones are placed near each other, but still with space between them; or when wireless microphone users stand next to each other. Also referred to as acoustic phase interference. See also "3:1 Rule".
