Re: Loudspeaker with directivity similar to a human talker

[Lissek Hervé <herve.lissek@xxxxxxx>]

Dear Xing,

Actually, there does not exist any loudspeaker that could perfectly match the acoustic radiation pattern of the human mouth/head. The ideal solution would be to use a Head and Torso Simulator such as Brüel & Kjaer Type 4128D (see http://www.bksv.com/Products/TelecomAudioSolutions/HeadTorso/HeadandTorsoSimulatorHATSType4128D.aspx), if you can get one.
Regards,

Hervé

Objet : Loudspeaker with directivity similar to a human talker

Dear List
 
  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? 
  
  Thanks,
