Acoustic clapper
Impulse source for impulse response measurement. It produces a repeatable impulse mechanically: nothing to power, nothing to explain to passers-by.
Planar loudspeaker
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.
Spherical loudspeaker
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.
Standard signal generator
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.
