Project Description

Auditorium Design for Acoustic Requirement

In all stadiums, the vast majority of auditorium design stadium is for comprehensive multi-purposes. In addition to sports competitions and training, it can also use for large-scale theatrical performances, conferences, fashion shows, film screenings and organizing acrobatics, circus performances. It is indeed multi-purpose auditorium. In order to meet the requirements of multi-purpose use of the auditorium design, it needs to do the professional acoustic solutions.
stadium wall acoustics design

The most important feature of the stadium is its large volume, resulting in the long reverberation time in the hall.

  1. the long reverberation time will reduce the acoustic clarity of the hall, to influence the listening of the audience.
  2. the long reverberation time will also cause howl round of the sound-reinforcement system.
  3. the parallel walls and the long sound path in the competition pool will cause flutter echo and multi-echo.
  4. the sound of players’ footsteps and crash will be more intense; it even involved into a strong buzz.
  5. the structures of stadiums are more diversified, because the architects are not satisfied with rectangular design of the past.
  6. The stadiums are circular, elliptical, and polygonal, in an inexhaustible variety.

All these curved walls and vaulted roofs will produce sound focus.
