TCR

TCR is a numerical code based on the Classical Theory or Reverberation.

Principle

The simulation code TCR (from French "Théorie Classique de la Réverbération") is a numerical application of the Classical Theory of Reverberation as proposed by Sabine. It allows to obtain an evaluation of the diffuse sound field in a single room on the basis of Sabine's relations for the reverberation time and for the sound level of the reverberated field.

  • Elements of validation
History

The TCR code was developed and is still maintained by the Environmental Acoustics Research Unit of Université Gustave Eiffel (formerly Ifsttar, formerly LCPC) since 2007.

Application domains
  • ROOM ACOUSTICS: diffuse sound field evaluation in a single room
Advantages of the current version
  • Instantaneous calculation of the diffuse field (reverberation time and sound level)
  • Include direct field calculation
Limitations of the current version
  • Based on the assumption of a diffuse field (Sabine's hypothesis)
  • No coupled rooms
  • No individual representation of first reflections (all contributions are included in the diffuse field)
