The existing ones weigh 30 kg and want 230 V on the third floor with no lift. Planned variants: standard 5 hammers, reduced version.
Architectural acoustics on a scale model: a miniaturised ultrasonic-band spark. Planned variants: 1:10, 1:20, 1:50 scale.
Impulse source for impulse response measurement. It produces a repeatable impulse mechanically: nothing to power, nothing to explain to passers-by.
Levelling on floors that are not flat, without altering the impact. Planned variants: set of 3, set of 4, with and without spirit level.
Known, stable sound power: it calibrates the method, not the instrument. Planned variants: 1 impeller, 2 impellers, low-consumption version.
Today the 45 degree angle is eyeballed; here it is read off a scale. Planned variants: 0-90 degree scale, with and without laser level.
Every serious omni on the market needs a flight case and two people. Planned variants: 12 segments, 20 segments.
Rain noise on roofs, skylights and conservatories. Planned variants: 1 m2, 2 m2, 4 m2 surface — low/medium/high flow.
STI and intelligibility: a speech source with standardised directivity and level. Planned variants: mouth only, mouth and torso, desktop version.
A dodecahedron that breaks down into segments: it fits in 30 L instead of a flight case. Planned variants: 12 faces (dodecahedron), 20 (icosahedron), 6 (cube) — 3"/4"/5" drivers.
Impulse response in large rooms (churches, theatres): support, aiming, protection. Planned variants: 6 mm / 9 mm calibre, with and without directional screen.
A repeatable burst: pressure gauge, inflation template, remote popper. Planned variants: 30 / 40 / 50 cm diameter — packs of 25 / 100.
Repeatable 1 m release height without a second operator. Planned variants: telescopic, tripod-mounted, wall-mounted.
A single repeatable impact, with known mass and height. Planned variants: 1 / 2 / 5 kg masses — 0.5 / 1.0 m heights.
A bench for verifying the omnidirectionality class of your own source. Planned variants: fixed laboratory version, portable field version.
Extension of the existing family. Planned variants: boards 20x30 / 30x40 / 40x50 cm — one or two hands, spring-loaded version.
One object instead of amplifier plus laptop plus interface; battery powered, IP54. Planned variants: 300 / 600 / 1200 W — 1 or 2 channels.
ISO 16283-3 loudspeaker method, 45 degrees incidence on the facade. Planned variants: 1 horn, 2 side-by-side horns, column version.
Retrofit for the 12/20 sphere already sold, without rebuying the drivers. Planned variants: for 6, 12, 20 drivers.
On-site check before the final layer goes down. Planned variants: single hammer, 3-hammer version.
Injection into an air duct for measurements on fans and air handling units. Planned variants: 100 / 160 / 250 / 315 / 400 mm diameter.
Excitation with measured force on structures and floors. Planned variants: 100 g, 1 kg, 5 kg, 12 kg — rubber/plastic/aluminium/steel tips.
Five 500 g hammers, 40 mm drop, 10 impacts per second. Today it costs as much as a used car. Planned variants: standard 5 hammers, lightened transport version, battery version.
Source for low-frequency impact noise. Planned variants: ball only, ball plus 1 m drop jig, ball plus container.
