Why don't the Spider-Men alert the people of NYC about the symbiote's weakness to sound?

I was replaying Act 3 and the JJJ podcast starts, the one where he says the people have gone to the forums to find any weakness that the creatures show. Why didn't the Spider-Men just use the YFNSM app to alert everybody to grab a pan and bat it when the symbiotes approach... I know it won't make them 100% symbiote-proof but it's still better than knowing nothing.
