Abstract
A portable calibration system is disclosed that calibrates an audio equipment without using a dedicated sound level meter. The calibration system comprises a coupler configured to couple a transducer to an energy sensor, where an output of the transducer is provided to the energy sensor via the coupler, an analyzer module configured to receive information from the energy sensor regarding the output of the transducer, a processor, in the analyzer module, configured to process the information to provide a result of a calibration for the audio equipment with respect to expected results, and a display configured to display the result of the calibration.
