a new improvement, I found that one tone is called Yelp, the other is called Zap, and I found a third one might be chirp, I wonder where they got these names from, the 3 of them are used in ambulances worldwide, so thats agood start, Next I will find their frequency pattern and I will publish it here if anyone interestesd.
