TOA | No.1 Share for Airport Broadcast Systems for International Airports in Japan
TOA's passenger announcement systems and emergency broadcast systems are hard at work at all five international airports in Japan. TOA's airport broadcast systems are also used at Charles de Gaulle International Airport in Paris, Heathrow Airport in London, and other major airports around the world.
TOA's expertise in the operation of sound at airports, such as types of broadcasts and priorities, sets TOA apart. Let's take a look at the second terminal of Tokyo International Airport (Haneda Airport) opened in 2004 where TOA's passenger announcement system and emergency broadcast system are in use.
The volume of announcements tends to be loud in order to overcome noise at spaces where many people gather, such as airports. Announcements reach people only if they are about 10db louder than the noise. TOA's passenger announcement system at Big Bird (Tokyo International Airport) is equipped with the Ambient Controller that automatically adjusts the volume in accordance with the noise level. The result is a quiet, comfortable environment where necessary information is thoroughly communicated.
The essential purpose of an emergency broadcast is to alert people who are in danger. A needlessly global broadcast may trigger panic involving people who are not in danger. Through its experience over many years, TOA has in-depth knowledge of the flow of people at airports. In compliance with the requirements of the Fire Services Act of Japan, we have established an emergency broadcast system that ensures delivery of necessary information only to necessary locations even if there is a power outage.
