LRAD Monthly Siren Testing For April 2023
Emergency testing of the notification system is actively underway on the first Saturday of the month at 12 noon within the City of Mill Valley, Tam Valley, Strawberry and Sausalito.
Long Range Acoustic Device (LRAD) emergency alert systems are unique in that they can project both siren and voice recordings to alert and inform community members during a large-scale disaster.
The "Did you hear it ?" (DYHI) campaign was developed to tap the abundant information available about the on-going monthly testing from the people who experience them. By taking advantage of the vast number of Internet users, we can get a more complete description of what people experienced, the effects of the monthly testing, and the extent of missing coverage. And best of all, with your help we can do so almost instantly.
