Which type of soundsource (normal LS - OMNI LS)

[sergioTOOL]

Hi

Anoooother question.
What kind of Loudspeaker you recommend using during the measurements with REW? (in my case I will carry out measurements in classrooms with the final aim of obtianing their RT60). I´ve read Omni sources are recommended placed at representative positions were the sound source will be (say front of the classroom were the lecturer will be, or the stage at a theater). Or with white noise and traditional loudspeakers locating these facing a corner in the room, aiming to spread the sound by means of reflecting it.

Many thanks
