2024 AES International Acoustics and Sound Reinforcement Conference in Le Mans, France

L-Acoustics is the platinum sponsor of the Audio Engineering Society (AES) International Acoustics and Sound Reinforcement Conference, which will take place in Le Mans, France from January 23 to 26, 2024. Arica Rust, a member of the Education & Scientific Outreach division at L-Acoustics, is co-chairing the conference whose objective is to bring together the minds of leading researchers and practitioners to discuss new ideas and to foster the next generation of industry innovators.

More than three years past since M-Noise was proposed as a new test signal for standardized measurement of a loudspeaker system’s maximum linear output, the Audio Engineering Society has announced the adoption and publication of AES75-2022, “AES standard for acoustics - Measuring loudspeaker maximum linear sound levels using noise.” The new standard addresses the need for a practical and cohesive procedure for the prediction of loudspeaker performance.

Within the audio chain, the loudspeaker could be the element that most influences a user’s auditory experience. A loudspeaker is not only the final element that converts electric input into an audible output, but it is also responsible for an increasing portion of the system’s cost, inefficiency, weight, and size, making it a crucial element for the costumer and the manufacturer. This article, published in Voice Coil, May 2016, discusses ways to use digital signal processing to improve loudspeaker performance.

In this fascinating article, published in audioXpress, October 2004, Nelson Pass investigates loudspeaker performance when driven by a current source amp. This extensive research shows what Pass and Kent English found with a variety of full-range sensitive loudspeaker drivers when they drove them with an active current source and played with parallel networks to shape the response to their liking.
