Omnidirectional Sound Source [Omni 4” HP]

The OMNI 4” HP offers a powerful signal source for room & building acoustics measurements. Power, manageability and portability are essential requirements for acoustic technicians: OMNI 4” HP represents the best solution between weight and power.

 

The new spherical sound source OMNI 4” HP printed with the innovative additive manufacturing system, is specifically designed to grant an improved sound radiation and a even close to perfection isotropy.

 

The OMNI 4” HP omnidirectional sound source works with a cluster of 12 ferrite speakers in a round shape that radiate sound in a spherical distribution.

 

Powerful, 128 dBA, suitable for sound insulation measurements in large spaces and high demanding walls and floors.

 

The reduced diameters of 280 mm allows it to be used also in limited space conditions.

 

With its spherical shape, all normative requirements on the source directivity are met.
