Omnidirectional, planar, directional and impulsive sources. What you need to excite a room or a facade while meeting the directivity and repeatability requirements the standard asks of the source, rather than simply making noise.
Heavy impact for timber floors and lightweight structures.
Even coverage of a 10-20 m facade without moving the source.
The 50-100 Hz extension required by the ISO 16283-1 low-frequency procedure.
Planar sound source for field measurements. The drivers sit on a single plane, so the energy goes in one direction instead of spreading through the room — which is what you want when the target is a surface: a facade, a wall, a window. A single driver: the smallest size in the range, for quick checks and for spaces where nothing else fits.
Modal testing on floors and facades without a hammer.
Static deflection of the floor as context for the acoustic measurement.
Change the excitation band without changing hammer.
Sources with a known spectrum, to check that the setup repeats.
A repeatable, omnidirectional impulse with no amplifier and no power cable.
Omnidirectional sound source. The drivers are arranged on a sphere so that the output is the same in every direction — the condition that environmental and sound insulation measurements ask of the source. Six drivers: the compact version, meant to be carried by one person.
Measurement on stair flights, improvised with bricks today.
Generator for the test signals used in acoustic measurements: sweeps and the like. One dedicated object that does one thing, instead of a software chain to reconfigure at every site visit.
ESS sweep, MLS, pink noise, intermittent noise, pure tones, standardised bursts.
No manufacturer has designed one with air travel in mind.
Surviving the van and the stairs.
Airtightness of windows and joints: transmitter plus directional receiver.
Repeat facade tests through the wet season, left on site.
Start and stop from the receiving room without going up a floor.
