Acoustic Sond

with programmable Intelligence

We’ve implemented an integrated (class A) sonometer (named Euterpe) for environmental sound-analysis. The hardware of the  integrated sonometer is based on a low-cost personal computer for digital signal-processing, a professional soundcard for data-acquisition and a measuring microphone. A windows based software-tool is implemented to integrate some extra functionalities like task scheduling, remote control, … with the traditional functionalities of a sonometer. This with the aim to facilitate unmanned environmental acoustic measurements.


 commercially available Soon...
expected second quarter of 2002

Virtual Acoustic


The aim of this project is to extend the developed integrated sonometer (see Euterpe) with a software-environment, which allows acoustic experts (with only limited programming knowledge) to define and implement specialized acoustic measuring tools. This makes the developed sonometer a generic environment that integrates multiple software-emulated measuring devices, which can be combined as required in the measurement campaign. The developed tool is a windows-based program, which allows one to define a measuring chain of interconnected operators. The user can simply drag and drop the operators in the environment and define how the operators are related.
