Announce Meter

 AnnounceMeter for smart building applications

● How understandable are announcements?

● Tune audio system to be understandable but as quiet as possible

● Retrofittable: connect to audio system and cloud by RF

● Energy harvesting of PA system Pilot Tone (20kHz)

● RF network mesh

● Application areas: airports, trains, stations, conference halls

 By using innovative linguistic and spectral processing of the audio stream, AnnounceMeter not only measures the power level of the audio, but also the „understandability“ of the spoken. AnnounceMeter optimizes the audio system locally and in real-time. AnnounceMeterV.0.1 uses Bluetooth 4.0 (BLE), able to network mesh. Functionality is proven by measuring the environment noise level. AnnounceMeter uses the pilot tone of the PA system to supply itself with power (energy harvesting)
