smartVES

Safety and intelligibility of announcements during sports events

smartVES can function as a public address system, supporting both daily communication during events and crisis management in sports and entertainment venues. The system is designed for professional event execution, enabling the host or commentator to convey information to participants and the audience.

The key role of smartVES is safety. In situations of danger, such as fire, riots, or sudden incidents, the system allows for rapid information dissemination. The system uses microphones placed in the stands to monitor the current noise level and automatically adjust the volume of announcements. This guarantees maximum intelligibility of the message for all participants and the audience, regardless of the surrounding commotion.

Standards compliance - full EN54 certification

High speech intelligibility, even in noisy environments

Supports the direction of evacuation traffic, minimizing risk and preventing dangerous bottlenecks on exit routes

Maximum flexibility and scalability, ensuring integration with other building systems (e.g., BMS, CCTV)

Intercom System

Crisis coordination during mass events

The Intercom System is a crucial element of stadium communication infrastructure, designed to ensure immediate information transfer between staff, security, medical services, and management. It is an essential tool for coordinating operations, crowd management, and rapid response in emergency situations.

The system ensures operational fluidity and safety during all critical moments:
- Stadium evacuation
- Incident management
- Crowd control

Stadium evacuation: Enables coordination of all exit points and security personnel in case of a threat (fire, failure, security incident).

Incident management: Allows for immediate notification of medical or technical services about accidents, medical incidents, or infrastructure failures (e.g., lighting, gates).

Crowd control: Facilitates constant communication between security teams to prevent dangerous behavior, quell disturbances, and manage traffic within the stadium.

Seamless voice information exchange at strategic points of the facility

Noise reduction and echo cancellation for clear sound

Robust device construction ensures long-lasting and failure-free operation

Easy integration with Public Address Voice Alarm (PAVA) and other security systems

Automatic recording of conversations and messages, essential for security analysis and post-crisis management

smartVES Intelligent Algorithms

STTA
Speech Signal Time Transposition
Algorithm

A function for adjusting the pace of announcements. The system automatically slows down announcements made by operators, which increases their intelligibility.

AF
Adaptive Filtration
Algorithm

A function for automatic volume and sound timbre adjustment based on real-time noise sensor readings. The system analyzes the noise spectrum and reacts to its changes by applying narrowband filters. This ensures that announcements remain intelligible, even in noisy conditions.

Intercom System Intelligent Algorithms

Noise reduction

Effectively eliminates unwanted background noise (e.g., street traffic, train noise) from the speech signal. Increases communication clarity in acoustically challenging locations.

Echo Cancellation

Detects and eliminates acoustic echo during two-way communication. Ensures natural and fluid conversations, improving user comfort.

Automatic Volume Control

Dynamically adjusts the audio signal volume to prevailing acoustic conditions. Maintains optimal speech intelligibility, regardless of changing environments.

Gateway System: Content Management and PA/PAVA Integration

The Gateway System is an integrating module that provides centralized management of commercial and informational content. It enables intercom integration with the public address system (PA/PAVA). It is equipped with a scheduler for automatic playback of advertisements, music, and announcements from a list. A key function is also the recording and archiving of all intercom communication, which is essential for security analysis and compliance with procedures.

Specialized loudspeakers for demanding environments

In locations with demanding acoustics and mounting limitations, the use of specialized loudspeakers is crucial.

They should be characterized by high efficiency, a wide frequency response, and controlled sound directivity. This approach allows for precise sound reinforcement in target areas, while limiting sound emission to adjacent zones and reducing unwanted reflections.
