AES75 2023: AES standard for acoustics - Measuring loudspeaker maximum linear sound levels using noise, details a procedure for measuring maximum linear sound levels of a loudspeaker system or driver using a test signal called Music‑Noise.
The standard is free for AES Members and can be obtained from this link. Non members are charged $100.00 USD.
An official AES75 Facebook group has been created, providing a growing community for connecting, sharing, and learning with people who are interested in AES75. It can be found at this link.
The Music‑Noise signal is provided in 48 kHz and 96 kHz sample rate versions. The standard also references three files which are used for characterizing the coherence measurement.
The Music‑Noise signals and the coherence test tracks may be downloaded in a single zip archive from this link.
