Clear announcements are distributed with TOA high quality and flexible sound systems.

Airports

Airports require specific announcements to be made in specific areas to help guide airport users to arrival and departure spaces. Offering the sound systems and engineering capabilities required for safe, reliable passenger transit, we enable the accurate transmission of information to passengers and smooth communication between airport staff.

What makes a good airport sound systems?

Airport announcements are an indispensable service to help airline passengers and anyone who meets or sees off passengers to accomplish their objectives. Airports are divided into areas for each process in the flow of arriving and departing passengers, and announcements should be distributed to the appropriate areas according to each purpose. In a well-designed system, paging zones are setup for each area.

Microphones with zone selection are properly placed and programmed with priority functions to precede others in case of emergency or superiority. Backup power sources ensure emergency announcements during power failures, and pre-recorded evacuation instructions can be automatically broadcast in coordination with fire alarm systems. The sound system design needs an acoustical approach as well as functional configuration. For the optimum intelligibility of announcement, the sound level of broadcasting needs to be 6 to 10 dB 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 speakers help reduce echo and reverberation. Ambient noise controllers are convenient tools to automatically adjust the suitable announce level according to fluctuating ambient noise. In addition, TOA’ s sound simulation software makes speaker selection and configuration super-easy.

Railways

TOA creates a completely reliable infrastructure environment, with clear announcements at the ideal volume in railway stations ensuring accurate information is delivered clearly. TOA provide a range of solutions to ensure that passengers reach their destinations with peace of mind, in comfort, and with informed messaging.
