I used a similiar MP3 setup for a call box. It had plenty of volume and range. A little harder to test with sounds we can't hear but I'm sure it would work. Even though the MP3 tracks are short you can have the MP3 player set to "repeat" tracks. Just turn it on if they start barking when you're outside working. If you want to get really creative setup a dual system, one speaker for the dogs and the other can handle the "Heavy Metal" for the annoying neighbors!

Maybe a little heavy metal, rap, Lawrence Welk and Barney.
