PSE01 - The Importance of Thermal Simulation in Loudspeaker Design: Case Study for a Compression Driver
Presenters:Marco Baratelli, Faital S.p.A. - Milan, Italy
Grazia Spatafora, Faital S.p.A. - Milan, Italy
Faital S.p.A. makes use of FEM simulation in order to predict heating phenomena and minimize the potential permanent damage to the coil for a wide variety of products. All heat transfer mechanisms are important: conduction, convection, and radiation. Compression drivers are high efficiency electroacoustic transducers dedicated to high frequencies. They are designed to produce high SPL levels, usually coupled to a horn or waveguide. Due to their spectrum of operation these devices experience incredibly small membrane excursions, hence they can be considered approximately static. In other words, compression drivers do not take advantage of the cooling effects that usually a woofer coil experiences while moving, as air is strongly pushed and pulled in and out of the air gap. For this reason these devices can be sensitive to severe heating, which in extreme cases can lead to permanent damage of the coil by combustion of the insulating enamel.
The outcomes of the presented case study were compared with an equivalent measurement. Results show a satisfactory match between the model and the measurements, with a worst case error of 5%.

PSE02 - The Advantages of Electronic Beam Steering and its Relation with FIR Filters
Presenter:Daniele Mochi, K-array - Florence, Italy
The ability to digitally adjust the dispersion of a line array element not only ensures the same listening experience to all audience members but, at the same time, limits the noise pollution in the areas where the sound pressure must be kept at a minimum. This presentation discusses advantages of Electronic Beam Steering (EBS) using FIR filters by providing extremely high frequency resolution.
Thursday, May 24, 12:00 — 12:45 (PSE Stage)
PSE15 - Progressive Directivity Array: Technology Overview and Performance Advantages for Sound Reinforcement Systems
Presenter:Moreno Zampieri, Bose Professional
The concept and advantages of Progressive Directivity Array (PDA) was introduced at the ISEAT 2015 convention. The primary advantage of the PDA compared to conventional approaches such as line-array or point-source speakers is that the intended tonality can be achieved regardless of the room conditions (shape and material) with consistency throughout the target audience area not just for a single listening point. The study clearly indicates that precise coverage control to match the audience area with continuity of the sound source without gaps between modules are two crucial elements to achieve the primary objective. In this session adaptation of the PDA concept to the real product as a modular approach is described with performance of the product followed by application of the products to real world examples.

PSE03 - The Effect of Acoustic Center in Subwoofer
Presenter:Paolo Martignon, Contralto Audio srl - Parma (PR), Italy
This presentation is the outcome of an investigation begun in 2017 which sees the collaboration between Contralto Audio and Merlijn Van Veen. It was already presented briefly in AES143 in New York and is proposed again in this context where more room for details and discussion is allowed. As explained by J.Vanderkooy in his paper “The Low-Frequency Acoustic Centre: Measurement, Theory and Application,” the acoustic center of a direct radiating subwoofer unit is placed ahead respect to the driver membrane, at a distance depending on driver and cabinet dimensions. This has effects on acoustic simulations and it deserves some attention to avoid errors. Measurements are shown that confirm acoustic center position theoretical calculation and a discussion is made about its effect on the definition of models for accurate simulations.
