CALIBRATION METHOD FOR CUSTOMIZABLE PERSONAL SOUND DELIVERY SYSTEMS

A method (100) for calibrating a sound delivery system (1) having a processing assembly, a data communications assembly (9) coupled to the processing assembly, and at least one audio transducer (21a, 21b) mounted with at least one processor (11) of the processing assembly and responsive thereto for delivering sound to a user (3), the method including the steps of: transmitting from a remote user interface device (6) for the sound delivery system, a sequence of command codes for specifying predetermined characteristics of test sounds; receiving the command code sequence at the communications assembly of the sound delivery system; providing the command code sequence to the processor assembly of the sound delivery system; reproducing by a selected at least one audio transducer, the predetermined test sounds under control of said at least one processor according to the command code sequence; measuring with a reference SPL meter (70) proximate to the audio transducer, characteristics of test sounds reproduced by the sound delivery system; comparing the measured characteristics of the reproduced sounds with the predetermined characteristics of the test sounds; producing a mapping of specified test sounds to sounds reproduced by said at least one audio transducer (21); and storing the mapping in an electronic memory (82) associated with the remote user interface device (6).
