This is wonderful!

Thanks Eva - it is a very unusual and elaborate approach to auditorium side-wall acoustics. Greetings, densil

Right! Ceramics? Did you notice if the acoustics were special?

Hi Eva, I guess I'm meant to be able to answer questions like that (it's my job). But it's a couple of years since I've heard a concert in this auditorium so my memory is a bit hazy. The concept is that the scattering surfaces produce a more even distribution of sound across the audience area, and remove any weird echo effects. Additionally, they provide increased loudness and reverberance, in part due to the greater sensitivity of the ears to sound that comes from the side. Although this auditorium has what we would call (in acoustics) a 'warm' sound (sufficient bass reverberation), the impression by audiences may be that the sound is a little cold - but this could be a multi-sensory interaction effect or more simply a mental association with ceramic surfaces. Hope that is not too much detail...
Friendly greetings, densil

Dear Tanya, thank you for your visit and very kind comment. Warm regards, densil

I suppose that acoustics change according how many people are in the auditorium.

densil on December 20, 2012

Yes, almost always the presence of an audience reduces the amount of reverberation. However, in some auditoria, a lot of effort goes into seat selection/design so that the occupied seat (including person) has a similar amount of sound absorption as the unoccupied seat. On the other hand, some auditoria have seats with relatively little sound absorption, so the audience changes the acoustics a lot (Vienna's Großer Musikvereinssaal is a prominent example of this - and it is regarded as one of the world's best concert halls). Mostly, acoustic measurements are made in unoccupied halls - if you make measurements in an occupied hall you need to make it entertaining.

Wonderful! And so is your explanation of auditorium acoustics. Thanks for both! L&F.

By the way, there was a brief explanation of the acoustics in the Sydney Opera House when I toured it, but I don't remember a thing! Lol.

Thank you very much, Diane! By the way, I have heard the well-intentioned tour guides say some quite strange things about acoustics at the Opera House, so it probably does not matter if you forget what they said.
