Dodecahedron is a sound source used to radiate uniformly a sound in all directions, allowing a correct insulation measurement and reverberation time both in building and architectural acoustics.

Manageability, assembling simplicity and portability are essential requirements for acoustic technicians: OMNI dodecahedron represents the best compromise between weight and portability.

OMNI 4” HP is used for passive acoustics requirements measurement due to the integration of the most updated technical features required for this kind of equipment.

In order to fullfill all the technical requirements set by recent standards, OMNI 4” HP is a unique combination of small dimensions, low weight, high portability to be suitable for all kind of measurements.

OMNI 4” HP is supplied with a 6 meters connector cable for the amplifier, in order to be moved easily inside the measurement field.
