Prism Sound's Queen's Award For Enterprise: International Trade 2011

Audio Test and Measurement Applications

Electro-acoustics

Design it, model it and analyse it!
Prism Sound is the world's only company that offers complete system modelling and analysis capabilities for acoustic transducer design. The LOUDSOFT suite of software modelling packages enables the engineer to design and model a complete loudspeaker - from motor and soft parts of a transducer through the enclosure and cross-over design. The dScope Series III Audio Analyzer is the world's only instrument that can analyze a complete electro-acoustic system including its loudspeaker, microphone, integrated analogue and digital amplifiers, A/D and D/A converters, and Windows® audio communication link (including USB and Bluetooth).
