Plugin
Still an open entry in the catalogue: a plugin to close the gap between the instrument and the analysis software already in use at the practice. The scope will be decided by the first requests — signing up is part of that.
Raspberry Pi controller/recorder with display
Control and recording unit built on a Raspberry Pi, with an integrated display. It comes from a site problem: starting and watching over a measurement without carrying a laptop. The design is already built and used in the field; what is missing is industrialisation.
Vehicle counter
Vehicle flow counter, designed as an input for road noise calculation. Declared error is about 10% on the flow. Because noise is logarithmic, that works out to roughly 0.4 dB on the calculated level — inside the uncertainty of any prediction model, and below the error introduced by estimated speed or road surface type. Positioning: accuracy adequate for acoustic calculation, not a general-purpose traffic counter. Transport engineering would need better than 95%, and the instrument is not suitable for that.
