Airport Solutions

Reliable Sound for Efficient and Safe Airport Operations

Airports are dynamic, high-traffic environments where clear and timely communication is essential - for both safety and a positive passenger experience. From routine boarding announcements to critical security alerts, every message must be delivered with precision, clarity, and in the right place at the right time.

TOA delivers integrated public address, voice alarm, and intercom systems designed to support smooth operations, guide passengers effortlessly, and ensure regulatory compliance. Through zone-specific announcements, scalable system architecture, and exceptional speech intelligibility, we help create airport environments that are safe, intuitive, and stress-free.

A Growing Need for Clear, Reliable Airport Communication

More than 2.5 billion passengers travel through European airports each year - with major hubs like Heathrow, Istanbul, and Paris-CDG each handling over 70 million travellers annually. (Statistic of Airport Association ACI Europe 2024)

As air traffic continues to rise, so does the complexity of communication. Precise, zone-specific, and intelligible announcements are critical to ensure smooth operations and passenger safety.

Our airport solutions are designed for:

Planners seeking compliant, EN 54-certified audio systems
System integrators looking for scalable, modular solutions
Airport operators requiring reliable communication and smooth passenger flow

IASI International Airport T4, Romania

Clear Communication for One of Romania’s Busiest Airports

With the construction of the new Terminal 4, IASI International Airport has significantly expanded its capacity and infrastructure. As the second largest terminal in Romania, T4 covers a total surface area of 31,250 m² across three levels and is designed to handle the estimated 3.5 million passengers annually. The entire development – including a new parking area, access roads and a photovoltaic park – was completed in just 14 months, with 75% of the €90 million investment funded by the European Union.

As part of this milestone project, a modern and future-proof voice alarm system was required to meet the high safety standards and operational demands of a busy airport environment.

Customized Safety and Efficiency

Our Romanian partner Romaudiovideo was responsible for the installation and chose the reliable TOA VX-3000 voice alarm system, integrating it seamlessly with various loudspeakers indoors and outdoors matched to the terminal’s different zones and acoustic conditions.

The system ensures clear and intelligible announcements throughout the terminal while enabling efficient communication between airport staff. Thanks to the integrated zoning function, areas such as check-in, baggage claim and boarding can be addressed individually or in combination, enhancing both safety and operational workflows.

Seamless Integration of Voice Alarm and Multilingual Airport Announcements

To provide a full level support and combined solution, TOA cooperates with solution providers in many fields. For Airports TOA cooperates with AviaVox, a provider of AI-powered, multilingual automated announcements. In combination with TOA’s EN54-certified VX-3000 system it ensures:

Natural-sounding, high-clarity voice announcements in multiple languages
Precise message targeting to specific zones - so passengers only hear what is relevant to them
Superior speech intelligibility in large, noisy airport spaces

TOA and AviaVox provide an unmatched level of speech intelligibility, ensuring passengers receive the right information - at the right time, in the right place.

Safety, Public Address and Intelligible Automated Voice Announcements at Airports

AviaVox entirely focuses on developing intelligent automatic announcement systems and services for Airports and Airlines. These systems and services can be used either separately or combined, as the topology is modularly designed. Whatever combination is used, the announcement policy of the customer is leading in how the system is being used. The software-platform enables AviaVox to tweak and tune the parameters in such a way that it entirely meets the expectations and requirements of the customer.

Throughout the years, AviaVox has developed specialized knowledge of the airport and airline operations and has tailor-made its systems and services towards the capability to integrate with the existing airport systems and operations.

That way the AviaVox systems are far more than just an intelligent automatic announcement system. Because it integrates with the Airport Operational Database (AODB), the Flight Information Display Systems (FIDS) and the TOA Voice Alarm and Public Address Systems (VA / PA). Also other structural components of the infrastructure like the Wireless Networks (Wi-Fi), the Local Area Networks (LAN), telephony switches and the Internet are being used to fully support Airport and Airline Systems as part of the daily operations, and help to maximize efficiency.

By combining TOA high-quality VA / PA systems with AviaVox human-like sounding Automated Passenger Announcement System (APAS), airports and airlines have the possibility to improve communication with their passengers on all levels. Delivering the right message at the right time in the right language and only in the PA- zones where it is needed.
