I found this when I was looking for existing lo-fi solutions.

Mace Screecher Aerosol personal alarm has a high-pitched shriek which can be heard up to 1/4 mile away.

Its convenient size fits into your pocket or purse.

Safety alarm features a 10-gram unit with a push-top activator and contains approximately 20 short aerosol blasts.
