TOA Solutions for Airport Environments
The main purpose of sound system at airport is to broadcast proper messages clearly to the people who need information. The sound system design needs acoustical approach as well as functional configuration. For the optimum intelligibility of announcement, the sound level of broadcasting needs to be 6 to 10dB higher than ambient noise and the direct sound should be much louder than the reflection.
However, actual airports are filled with ambient noise, echo and long reverberation, consequently announcements are prone to be unclear. In those areas the speakers must be appropriately selected and located according to the architecture and ambient noise. Line array speaker helps reducing echo and reverberation. Ambient noise controller is a convenient tool to automatically adjust the suitable announce level according to fluctuating ambient noise. In addition, TOA’ s sound simulation software, available free of charge, makes speaker selection and configuration super-easy.
