The full Athexo catalogue: acoustic instrumentation, field equipment and software for the acoustic consultant. Instruments designed in-house, plus the supporting kit needed to take them on site.
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.
An environment where standard optical sensors fail.
Extension of the launch product.
Overnight condensation means sensitivity drift.
Train passes, ground-borne noise.
Repeat facade tests through the wet season, left on site.
The link between draughts and a collapse in insulation.
Quick fixing without drilling and without asking permission.
They are bought blind: nobody publishes a measured insertion loss.
Start and stop from the receiving room without going up a floor.
