R&D Stories: Measuring the Performance of Diaphragm Absorbers

In August 2018, as part of its Focus on Acoustics edition, audioXpress published an article documenting the cutting-edge research by leading acoustic experts, Jorge Castro, Nathaniel Bailey (Artnovion) Bruno Fazenda, Kelvin Griffiths (Sense Research, Electroacoustic Design) to determine improvements on precise low-frequency absorption, leading to Artnovion's latest Eiger Sub Trap range of acoustic panels.

In August 2018, audioXpress published an article documenting the cutting-edge research by leading acoustic experts, Jorge Castro, Nathaniel Bailey, Bruno Fazenda, and Kelvin Griffiths to determine improvements on precise low-frequency absorption. The tests, performed at Electroacoustic Design, in Porthcawl, South Wales, UK, determined a method to predict finite element analysis of the performance of weighted diaphragmatic membrane absorbers, the predominant acoustic core now employed in Artnovion's latest Eiger Sub Trap range of acoustic panels.

Acoustic Geometry announced the launch of Pro Room Packs, a unique grouping of acoustical products aimed at the professional audio market. Delivering professional-level acoustical performance at four cost-saving price points, these new product packages include Fabric-Wrapped Panels and Ceiling Clouds (absorbers), Curve Diffusors, CornerSorbers, and all mounting hardware, providing convenient and well-balanced room treatment solutions for studios and high-end audio rooms.

Acoustic Geometry, a company offering best-in-class acoustic products for a wide range of professional audio, residential and business applications, announced the newest addition to its Acoustic Bass Management (ABM) product line, the CornerSorber. These corner bass absorbers utilize Mass-Loaded Vinyl (MLV) absorption membranes in a cutting-edge design that mitigates low-frequency room modes for the most accurate sound reproduction in a room.

The upcoming AES 59th International Conference, on Sound Reinforcement Engineering and Technology, will feature a special workshop hosted by Flex Acoustics and will include a demonstration of Flex Acoustics' inflatable membrane low-frequency absorbers, showing the overall effectiveness of their innovative acoustic absorption at low frequencies.
