The signal used in australia in the event of a terrorist attack, natural disaster, dam failure, nuclear explosion, large bushfire, disease outbreak and hazardous materials.
This is a sound of Police siren and it last for around 50 seconds. This is a European cop or policia. Great for emergency or cop scenes for movies based in the EuroZone.
American signal t-128 and federal signal 2001 siren sounding in attack mode. These sirens are normally sounded in a steady tone for tornado warnings, but this rising and falling tone would be used for civil emergencies like an air raid or other attack on the city.
An emergency siren, electronic. Rapidly switching 440 and 640 hz. Tones. Made in audacity, by me. Please, feel tree to use in any way, shape or form, but be sure to give me credit. Thanks!.
Sound of an emergency shut-down on a spaceship. A robotic voice is saying "enemy detected" attended by a brutal alarm sound. Maybe in a wide room or hall. I created this sound by using the fl studio speech synthesizer plus several effects. Maybe useful in a video game or a short animation movie ;-).
Self-created fire alarm. The idea is based on the typical fire alarm in buildings and was supplemented by a typical (slightly pitched) sound sequence of the us emergency vehicles. The sounds and the composition were created completely with audacity. I would be happy about suggestions for improvement and how you have used the sound sequence. I used it as a fire alarm in my home automation.
