AES75 Users and Resources
Access resources, test signals, measurement solutions, service providers, and implementation guidance for AES75, the standard for measuring maximum linear sound levels of loudspeakers using noise-based test signals.
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.
Music‑Noise test signals
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.
The checksums for the Music‑Noise signals are:
48 kHz: SHA1 = 46672df0844964f470f1f8eeea1a35099257a9d0
48 kHz: MD5 = 04b8b55e9490fc4c91fc81d4f3ebee41
96 kHz: SHA1 = 30686cdfcb7b277e8b8953416597aa21c65cd208
96 kHz: MD5 = 6539f08317d36216c3e0c37cf68c2b38
