||In performances where actors play among the stalls area, the audience feels to
participate in the show. Unfortunately, is impossible to avoid that the actors are always
backwards to some spectators, where the speech is not well followed. Using electroacoustic
systems, will break the realism that theatre performances have.
Therefore, a natural solution is provided by finding positions in which the speech can be
followed easily for the entire audience, included backwards the actor.
A black box theatre with all the different type of stages have been modelled at ODEON,
according to measurements in situ: conventional stage, extended stage and theatre-inthe-
round. Later, a deeper analysing on finding the optimal directions for speech was
worked before running the simulations. Finally, a robust statistical method was traced
when filtering improvements in between different simulations.
The optimal position for an actor to perform was achieved for different 5 mean specific
cases of study. The results show, by just moving the actor from 1m to 3m meters, is
possible to increase the average perception of speech definition of an audience above
500 seats. A general procedure for finding the optimum speech position for black box
theatres and an optimum speech angle aperture are purposed. It has been demonstrated
that all the spectators located within this optimum aperture will perceive the speech
parameter D50 as good as if they were seating in the frontal actor’s direction. Besides, a
design criteria concerning the distance in between the stage and stalls disposition for
conventional theatres, can be work out taking into account this optimum speech
aperture. Also lateral reflectors are purposed to be designed according to it.
