"M-Noise™: a live demonstration showing the process of determining a loudspeaker’s maximum linear peak SPL using a new test signal that resembles a music signal.

Professional audio engineers and consultants rely on manufacturer supplied maximum SPL specifications to predict a loudspeaker’s performance in the field. These specifications, and the test procedures that create them, can vary dramatically between manufacturers and in critical ways fail to represent the loudspeaker’s dynamic performance when reproducing our most important type of program material: music.

There is a clear need for a standardized test signal and procedure capable of accurately and objectively modeling a loudspeaker’s ability to linearly reproduce musical signals. M-Noise is a new open source test signal developed by Meyer Sound to overcome discrepancies between previous generation test references such as pink noise and real-world program signals. M-Noise simulates the dynamic response of music over frequency, and thereby, more accurately models loudspeaker performance under real-world show conditions regardless of the loudspeaker brand. An Audio Engineering Society (AES) task group is currently exploring adoption of M-Noise and its accompanying test procedure into an industry standard.

This presentation will describe M-Noise development, its unique characteristics and how it enables the effective measurement of a loudspeaker’s linear peak SPL. A live demonstration will then show the step-by-step M-Noise test procedure and determine the linear peak SPL capability for an actual loudspeaker.”

Participation is free of charge for AES-members. Non-members participation: € 10,- (student non members free admission).
Free admission also for: Members of NAG, VCA, VPT and students and staff of the Koninklijk Conservatorium.
Please note: application is compulsory in order to be able to participate.

how to get there:
The Royal Conservatory is situated at a walkable distance from the railway station 'Den Haag Centraal'. By car, arriving via A12, take exit 2 (Centrum). You will find the Conservatory at the end of the exit, after a right turn, immediately at your right hand side. For your convenience a map is provided at the bottom of this page.
On the Royal Conservatory website you will find more extensive route information.
