About AXYS Tunnel by HARMAN Products
HARMAN’s involvement in tunnel public address systems started when HARMAN acquired Duran Audio, now Axys Tunnel, in October 2013.
Over the years, Axys Tunnel’s R&D team dedicated their time to creating innovative solutions to real-life electro-acoustical problems such as poor intelligibility in public address and voice evacuation systems.
VA (Voice Alarm) or PA/VA (Public Address/Voice Alarm) audio systems are now commonplace in large public spaces & transport facilities. A well designed and commissioned system can deliver highly effective public communication. The goal of such systems is to clearly and intelligibly communicate emergency information so that people can move to safety as quickly and effectively as possible. To achieve this, a STI (Speech Transmission Index) of 0.45 to 0.5, under all conditions, is recognized as the minimum desirable standard. Furthermore, the system should be sufficiently robust to make individual component failures tolerable. In addition, comprehensive system component status monitoring, fault logging and reporting, maintaining a flexible set of audio processing techniques, and a simple, centralized point of system control and monitoring are all clearly desirable.
Axys Tunnel & HARMAN are the experts in this field. We introduced the Intellivox range of DSP-based active loudspeakers in the mid-1990s, which have since been installed in many major public spaces worldwide, setting new standards for speech intelligibility.
In 1999, we introduced the ABF-260 tunnel horn loudspeaker, specifically designed for use in the extremely hostile environment of public road and rail tunnels. Since then, we have expanded our portfolio further to include a range of complementary audio components, which may be used in combination with our loudspeakers to produce a system that delivers maximum intelligibility with the utmost reliability.
HARMAN’s highly successful range of road tunnel public address solutions are available worldwide through our worldwide network of specialized tunnel partners. In addition to public address solutions, HARMAN is able to provide tunnel architectural lighting solutions through our Martin Lighting brand and audio, video and control solutions for Operations Centers through our AMX brand and displays from SAMSUNG Electronics. HARMAN is a wholly owned subsidiary of SAMSUNG Electronics.
