Outline adds acoustic analysis system
- Details
Optimised acoustics are a prerequisite of many modern buildings and for some (classrooms, offices, theatres, and concert halls for example), their acoustic properties determine how well they are able to perform their core purpose.
Accurate and reliable test data is essential for those engaged in the design and construction of these spaces: a powerful omnidirectional sound source is vital to assist in the testing of acoustic insulation of internal walls, floor slabs, and insulation from the external environment, plus the acoustic properties of any internal space where sonic performance is important.
GSR’s design combines a robust spherical enclosure with an Ergal aluminium inner structure that houses twelve 5” neodymium-magnet transducers and is the first such device to include a bass reflex design to extend its frequency response.
Its ‘globe’ design eliminates 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.
The GSR is also available as a part of a complete user-ready kit, comprising a GSR, an NG01 Noise Generator, a compact amplifier (Outline’s L3000) plus the necessary cables, a transportation bag and a set of mounting accessories, providing a portable setup ready for immediate deployment. A dedicated self-powered subwoofer kit is also available and is suitable for applications where measurements of low frequency data are required.
