After I heard they do music 3 times a day I had to go listen to one of the blasts. This Modulator 6024 failed, but I could hear ones coming form the main base doing the music. I was told, and he/she was right, that the music isn't even nearly as loud as the main tones. Sorry about the cars ruining "Star Spangled Banner". Enjoy!
