Some examples and use cases from the internet:

• With the new wide dispersion constant directivity horn, sound expands in a more rectangular pattern providing 90º horizontal x 60 º vertical coverage, with wide
• Typically, for moderate to large events, the pattern of peak ground velocity reflects the pattern of the earthquake faulting geometry, with largest amplitudes in the near
• new 90ºx 60ºconstant directivity horn, designed with the goal of minimizing radiation pattern deterioration in oblique directions as more conventional horns are prone to doing.
• frequency sound projected to the edges of the coverage area.
• The HF transducer is mounted to an all
• source region, and in the direction of rupture (directivity).

• For propeller aircraft directivity variations are negligible and for these it may be assumed that
• This latter difference is due to lateral directivity (engine installation effects) and lateral attenuation.
• uniform directionality of sound radiated laterally about the roll axis of the aircraft, referred to here as lateral directivity.
• Wide sound directivity for flexible listening placement
• Specific Treatments of Ground
• This results in a non
• The innovating design allows to obtain an high vertical directivity and a high gain.
• ? Depression angle (lateral directivity parameter)
