After historical research has applied to the visual aspects of human perception for a long time now, as of recently the investigation of acoustic matters arouse an increased scientific interest too.1 So far still largely unresearched has been the concrete speech situation in premodern times before electro-acoustic amplification. In a large-scale study the department of ancient history in close collaboration with acousticians of the Frauenhofer-institute as well as other research disciplines attempts to adequately reconstruct and simulate ancient historic speech situations.

4. the curia Iulia as research project
• 52 BC: The senate building burns and P. Clodius Pulcher with it.
• By no later than 45/44 BC and in the context of the construction of the Forum Iulium a
new Curia is enacted.
• 29 BC: The curia Iulia is dedicated by Octavian, the later Augustus.
8. the curia Iulia as research project
“1. The treasury, prison, and senate house ought to adjoin the
forum, but in such a way that their dimensions may be
proportionate to those of the forum. Particularly, the senate house
should be constructed with special regard to the importance of the
town or city. If the building is square, let its height be fixed at one
and one half times its breadth; but if it is to be oblong, add
together its length and breadth and, having got the total, let half of
it be devoted to the height up to the coffered ceiling.
2. Further, the inside walls should be girdled, at a point halfway up
their height, with coronae made of woodwork or of stucco.
Without these, the voice of men engaged in discussion there will
be carried up to the height above, and so be unintelligible to their
listeners. But when the walls are girdled with coronae, the voice
from below, being detained before rising and becoming lost in the
air, will be intelligible to the ear.” (Vitr. 5,2,1f.)
9. the curia Iulia as research project
[17,75 m (w) + 25,63 m (l)]/2 = 21, 69 m (height
according to Vitruvius).
approximate real height: 23,40 m
