Abstract
Embodiments include a device comprising a pipe having at least one section that spans between a first end and a second end of the pipe. The pipe has a cylindrical cross-section. The device comprises a receptacle positioned in the pipe a first distance from the first end and a second distance from the second end. The receptacle receives an electronic device having microphones that are to be calibrated and secures the microphones a third distance inside an inside surface of the pipe. The device comprises an adapter connected to the first end. The adapter connects a loudspeaker to the pipe. The pipe controls an acoustic energy experienced by the plurality of microphones so that each microphone of the plurality of microphones receives equivalent acoustic energy.
