Meyer Sound Introduces M-Noise Test Signal for ‘Real World’ Loudspeaker SPL Measurements

Meyer Sound has introduced M-Noise, a new test signal that will promote standardized measurement of a loudspeaker system’s maximum linear output. A mathematically derived test signal that effectively emulates the dynamic characteristics of music, according to Meyer Sound, M-Noise enables a far more accurate measurement of a loudspeaker system’s linear peak SPL in any application requiring reproduction of musical content.

With the announcement of its brand new APx555 B Series two-channel audio analyzer, Audio Precision also unveiled the updated version 5.0 of its APx audio measurement software. With this release, AP has added the ability to measure the transfer function of electronic audio and electroacoustic devices using any broadband signal. Release 5.0 also enables electronic activation of software option licenses, eliminating the iButton requirement for such options with earlier versions of APx audio measurement software.
