Public Address and Voice Alarm Systems
| ASL Safety & Security | ||
Dynamic ambient noise sensing (DANS) improves platform announcement audibility and assists noise abatement. |
Microphones and other sensor equipment on ASL's units have been modified to operate in sub-zero temperatures beyond the Arctic Circle. |
Audibility of platform announcements is a crucial performance criterion for ASL. |
ASL's iPAM products not only offer core public address on platforms and concourses but function as a general customer information system (CIS) and can also provide digital voice announcements (DVA) as well as text to speech. |
