Safety whistles have been used for personal protection for a long time.  Current technology provides a high volume safety whistle emitting 122Db ear-piercing shriek at under $7.00 in US (no battery required) with basic whistle available for under $2.

The "panic button buddy" would be a carry-able device, similar to an electronic car key, which would attract attention by emitting a loud alarm and sending GPS info to a community base and/or local authority.

A part of being safe in an urban area is knowing what’s around you. With blind corners, alleys, construction sites, abandon buildings and other obstructions your safety is endlessly imperiled. The question for the research here is would it be possibl

Natalia commented on A Woman Whistles, Community Listens

Thanks for the idea. I think this should be technologically possible, the main thing is to make it very loud and to educate the community about the meaning of the call.

I think the main development of the idea would be to integrate it with the community structure including a) identifying police in the radius of the whistle being blown and teaching them what the whistle sound means; 2) identifying buddies along the way (idea was developed later in this challenge); 3) identifying a network (not necessarily of close buddies) but of people who agree to respond if they hear the whistle

I like this idea. I thought about modifying my "whistle" in this way, but wondered if technology would be affordable enough. I think it should be.
