The new GSR (Global Source Radiator) acoustic analysis tool from Outline.

Outline has announced GSR (Global Source Radiator), a new tool for acoustic analysis designed in collaboration with the Department Of Mechanical And Industrial Engineering at Brescia University in Italy.

GSR is designed to provide accurate and reliable test data regarding the acoustical properties of spaces such as theatres, concert halls, classrooms and more, assisting in the testing of acoustic insulation of internal walls, floor slabs, and insulation from the external environment plus the overall acoustic properties of the space.

GSR can also be used automotive, industrial, scientific, commercial and other applications because numerous acoustic parameters can be derived from measurements made using it as a sound source, including Clarity Indices (C50, C80), Intelligibility Indices (AlCons, STI, RASTI etc.), Reverberation Time (RT60), Early Decay Time (EDT), Soundproofing Power, Impulse Response and Intensity (G) and others. GSR is also fully ISO10140, ISO354, ISO3382 and DIN 52210 compliant.

Its design combines a spherical enclosure with an Ergal aluminum inner structure that houses twelve 5-inch neodymium-magnet transducers and in a bass reflex design that’s intended to extend frequency response. A truly spherical device, a unique “globe” design helps eliminate diffractions, reflections and other anomalies caused by non-spherical radiators that can compromise the accuracy of data measurement.

GSR is stated as capable of producing a maximum SPL of more than 130.3 dB from a spherical loudspeaker measuring just 31 centimeters in diameter. It’s also available as a part of a user-ready kit, comprising a GSR, an NG01 Noise Generator, a power amplifier (Outline’s L3000) plus the necessary cables, a transportation bag and a set of mounting accessories. A dedicated self-powered subwoofer kit is also available and is suitable for applications where measurements of low-frequency data is required.
