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.

Dear List<br>

 =C2=A0I would like to use a loudspeaker with directional properties simila=
