Re: Loudspeaker with directivity similar to a human talker

[Tony Miller <antonio.miller@xxxxxxxxx>]

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.
