Recent conferences

April, May and June have been busy for the Odeon team with exhibitions at four different international events:

Acoustics 2012, Nantes, France. Very well attended conference with busy exhibition and a wealth of papers.


Hong Kong Wang and Rindel

Acoustics 2012, Hong Kong.

Many participants from China, South East Asia and North America. Odeon A/S presented a paper on open plan offices and ISO 3382-3.

Papers from the Hong Kong conference with interesting examples of ODEON used for the design of new auditoria in China:

Y. Zhao, S. Wu: Acoustical Design for Concert Hall in the Science and Art Centre of Xiamen University. Paper 3aAA2 (1308).

J. Wang, K. Zhang: Acoustic Design of the Philharmonic Hall in the Shanghai Oriental Art Center. Paper 3aAA12 (1347).

EuroNoise 2012, Prague, Czech Republic.  Odeon A/S presented an invited paper for the special session on open-plan offices.

BNAM 2012, Odense, Denmark. Odeon A/S presented a paper on noise in eating establishments. Another paper that might be particularly interesting for ODEON users:

C.M. Petersen: Music-school concert hall – flutter echo treatment.


Restaurants

Canteen DTU
Noise from many speaking people in restaurants and other eating establishments is a widespread, but very difficult problem, which is now being dealt with by Odeon A/S.

The problem has been attacked from two sides:

  • How to define acoustical criteria for acceptable or sufficient acoustics in restaurants.
  • How to calculate the ambient noise level with a certain number of dining people.

In order to achieve a sufficient quality of verbal communication in a restaurant a new concept called ‘Acoustical Capacity’ has been suggested; this corresponds to an average signal-to-noise level of -3 dB in a distance of 1 m or an average ambient noise level of 71 dB(A). For further information see:

J.H. Rindel: Acoustical capacity as a means of noise control in eating establishments. BNAM 2012, Odense.

A new prediction method has been developed for ODEON taking the Lombard effect into account. The sound source is a transparent surface source placed just above the heads of the people. The source has the spectrum of speech at a vocal effort adjusted according to the actual acoustical feedback and the assumed number of people. For further details see:

J.H. Rindel, C.L. Christensen, A.C. Gade: Dynamic sound source for simulating the Lombard effect in room acoustic modeling software. Inter-Noise 2012, New York.

If you want to use the method for your own projects, a new Application Note for ODEON will guide you through the simulations.
