Emergency Alert Test

I heared the emergency alert siren being tested in our neighborhood again today. They seem to test the emergency equipment every now and then, probably once a month or something. During the testing process, the voice in the speaker says that this is only a test. I live in a busy area and a busy freeway is not very far. So when we go outside, we hear a bunch of car noises in the air. And there are some good winds in the area too. So everytime the emergency alert system goes off for a test run, its always been hard to really understand what is being said in the speaker. People can probably pick up few words when they are outside, but I can hardly hear the siren when Im indoor with the tv or music on. I think, inorder for it to be very effective and let everyone in the area hear the siren and hear what is being said in the speaker, it would be better if they add more speakers in so much square block, just to make it more effective and reach all people, not just some people. With the cars and winds blowing, the sounds that travels thru the air seem to be distored and other times just blown elsewhere and remain unheardable.
