Overcoming the barriers of language and conveying all the necessary information accurately

Airport passenger announcement broadcast system

The international airport terminal is the gateway to the sky. Precisely because it is a place where many people of diverse nationalities come and go, an infrastructure for conveying information accurately and reliably is critical. Our “airport passenger announcement broadcast system” with its multilingual capabilities allows for announcements about flight information, emergencies and the like to be made in a variety of languages, which makes for a more comfortable travel experience and smoother airport management.

Wide-area anti-disaster broadcast system

We provide systems that transmit sound over a wide range so that warnings of coming danger can be heard by everyone be they outdoors or inside. To list just two examples, we have our “Horn Array Speakers” that can convey sound more than twice that of traditional models and our “IP-Based Notification Systems” that are used for simultaneous broadcast from, for example, a city hall to the various municipal facilities under its watch. Systems like these contribute, with the sound they convey, to disaster reduction and prevention.

Disaster Reduction & Prevention

Natural Disasters That Cannot Be Avoided

In recent years the world has been shaken by many large-scale natural disasters including earthquakes and tsunami, torrential rains and volcanic eruptions. Japan is expected, with a high probability, to experience a massive earthquake in the Nankai Trough in the near future, which could cause up to 330,000 deaths. Against this backdrop, disaster reduction and prevention are growing ever more important.

Sound That Protects People From Natural Disasters

When a disaster occurs, sound-based guidance plays an incredibly important role in protecting people’s safety. TOA has, since its founding, sincerely striven to use its sound technologies to achieve disaster reduction and prevention, protecting people’s lives and minimizing the damage caused by these disasters. These technologies include a broadcast system that can connect quickly to all facilities in a network and broadcast equipment to convey a clear sound over great distances and warn people of danger. TOA’s technology is widely sought after by those working in the field to reduce and prevent disasters.

Using Audio and Visual Technology to Achieve a Safe and Secure Society

TOA’s security cameras are always on the lookout to prevent crimes and accidents all across town. Our company has surpassed the limits of what a security camera was able to do in the past, increasing the range of surveillance and providing sound alarm and announcement functionality. These new features are in line with TOA’s goal of creating a safer and more secure society.

Bringing disaster prevention closer to children

Puppet play “The Lookouts of KanKan Tower"

Human society is full of sounds that warn of imminent danger. When you hear an unusual sound you cock your ears and act appropriately. In order to convey the importance of listening to the next generation, we created this puppet show for kids.
