Recorders, synchronisation, connectivity and complete stations. Measuring for days without a laptop running in the van.
Recording without a laptop, with a declared runtime.
The market claims accuracies it cannot hold. Declaring 10% is the product.
It exists in the seismic field, not in civil acoustics.
Measurements headed for litigation or a formal complaint.
Microphone, front end, power and connectivity: open it and measure.
Freeing the data from the manufacturer's software.
Record the events, not 72 hours of silence.
Coverage inside a metal cabinet or a basement.
Two distant stations sharing the same clock.
A remote station you can query from the office.
The operator notes "a lorry is passing" without touching the PC.
Thirty stations, three jobs, one dashboard.
Ten points writing into a single database.
The parts exist; the tested kit that works without a systems integrator does not.
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.
Not driving 80 km to press a button.
Beamforming and correlation across several nodes.
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.
The SD card that corrupts at the end of the campaign.
Extension of the existing family.
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.
