Emergency Mass Notification systems are becoming increasingly intertwined and technologically complex. They bridge numerous platforms to alert people of possible dangers and also to guide them through the situation to safety. They can be controlled through a combination of fixed-location and/or mobile command centers when responding to weather-related or natural disasters or incidents such as campus shootings, hostage situations or fire-related evacuations.
Loudspeaker systems play a huge role in effective emergency mass notification operations.
- Portable, tactical systems can be carried into any location or mounted on vehicles and vessels.
- Deployable systems can be quickly setup in a strategic location to instruct crowds at an incident site or at a temporary shelter or base camp and provide 3600 coverage.
- Acoustic hailing devices (AHDs) can be set up on stands or mounted on vehicles to provide instructions.
- Fixed-location systems can cover a college, hospital or commercial campus or any designated public area to provide instructions.
Effective loudspeaker systems should have the power to exceed ambient sound levels by 10 decibels in order to be heard, and they should exceed the absolute minimum standard for voice clarity. That level is that 50 percent of words be understood – a 0.5 intelligibility level – but that’s inadequate. Having 70 percent understandable – a 0.7 intelligibility level – is more acceptable, but a higher level is better still. Intelligibility levels above 0.8 would be much better.
SoundCommander® loudspeakers from IMLCORP can meet all the logistical requirements of emergency mass notification systems with the volume and voice clarity needed to move people to safety. Emergency-response commanders can access prerecorded warning tones and messages (in multiple languages) to take control of a situation or make live-voice announcements.
Through a command center, they can integrate with other platforms in a system that also includes telephone, email and SMS communications and signage. Because each fixed-location speaker can be assigned an IP address on an emergency-management network, commanders can select the areas they need to reach with specific instructions.
