Transportation hubs, such as airports, train stations and bus terminals, require intelligible announcements and provide an indispensable service to help 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 set up for each area. Microphones with zone selection are properly placed and programmed as a priority function to precede others in case of emergency or superiority. Backup power sources, drives emergency announcements during power failures, and pre-recorded evacuation instructions can be automatically broadcast in coordination with fire alarm systems.


The main purpose of an audio system at in these busy hubs 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 10 dB higher than ambient noise and the direct sound should be much louder than the reflection. However, many facilities 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 reduce echo and reverberation. Ambient noise controller is a convenient tool to automatically adjust the suitable announce level according to fluctuating ambient noise.


General Announcement

Includes paging and general instructions for transportation users and is broadcast to specific areas or to all areas from a microphone at or operation center, you choose. Background music is often distributed through the same system to create a comfortable atmosphere.

Departure and Arrival Announcements

When leaving on vacation or picking a family member up from the airport or train station, ensuring travel information such as carrier name, flight number, departure time and boarding gate are clear is vital. These announcements direct passengers to where they need to be, smoothly and safely. Utilizing TOA’s full PA solutions, facilities will increase traffic efficiency while keeping travelers happy.

Emergency Announcement

The most critical of all public addresses are made in case of emergencies such as fire and other such events. The announcement overrides other what is currently being broadcast, such as background music, at maximum volume. If necessary, preset automated evacuation announcements to activate in coordination with the fire alarm or other warning systems.
