Re: Loudspeaker with directivity similar to a human talker

    I think every loudspeaker of the same size a human head has would comply. Norsonic recommends using a Tivoli loudspeaker to measure STIPA with Nor140 analyzer.

Suggesting a head and torso simulator (HATS) might be overkill on your budget if you are just interested in getting the directivity of an average human mouth.

The GRAS mouth simulator has an internal amplifer:

The B&K mouth simulator requires an external amplifier:

Both mouth simulators conform to standards: IEEE 269 and ITU-T P.51.

 I would like to use a loudspeaker with directional properties similar to a human talker to play the speech signals in rooms for speech intelligibility test.  I do not know which loudspeakers have directional properties similar to a human talker. Could someone please recommand a loudspeakers for my work?
