The spherical acoustic analysis tool has a “remarkable performance”
The Italian audio manufacturer Outline has developed a new tool for acoustic analysis, in collaboration with the Department of Mechanical and Industrial Engineering at the University of Brescia.
GSR’s design combines a rugged spherical housing with an internal Ergal aluminum structure that houses twelve 5-inch neodymium magnet transducers and is the first such device to include a bass reflex design to expand its frequency response.
It is also the only truly spherical device of its kind available today, its globe design eliminating diffractions, reflections and other anomalies caused by non-spherical radiators, which can compromise the accuracy of data measurement.
The GSR is capable of producing a maximum SPL of over 130.3dB, a figure well ahead of any comparable product currently available, and remarkable output from a spherical speaker just 12 inches in diameter.
The GSR is also available as a complete ready-to-use kit, including a GSR, NG01 noise generator, compact amplifier (Outline’s L3000) as well as the necessary cables, a carrying bag and a set of ‘mounting accessories, providing a setup ready for immediate deployment. A dedicated self-powered subwoofer kit is also available and is suitable for applications where low frequency data measurements are required.
Optimized acoustics are a prerequisite for many modern buildings and in some cases, for example for classrooms, offices, theaters and concert halls, the acoustic properties actually determine how well they are able to perform. their main goal.
Accurate and reliable test data is essential for those involved in the design and construction of these spaces: a powerful omnidirectional sound source is vital to help test the sound insulation of interior walls, floor slabs and flooring. ‘insulation from the external environment, as well as the acoustic properties of any internal space where sound performance is important.
The utility of the GSR also extends to the automotive, industrial, scientific, commercial and other fields, since many essential acoustic parameters can be derived from measurements carried out using it as a sound source: 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 d ‘others can be determined. The GSR is also fully compliant with ISO10140, ISO354, ISO3382 and DIN 52210 standards.
