Now how that sound to y'all?
Maybe how dog whistles sound to dogs
To the simple-minded listeners (in this case, dogs), Lu’s elevated lyricism which is often used to teach/discipline (much like a dog whistle) just sounds annoying and hurts their ears, whereas to him, as the human blowing the whistle and creating the tone, he’s immune to the sound(the silencer from the previous line)and understands its greater overall purpose.
Also since dogs don’t seem to understand human language, Lupe could be using this to point out how he’s been saying this for years and no one been paying attention until now that the dog whistle has been blown.
Though despite popular belief, dogs do seem to be able to understand human languages to a certain extent. So perhaps Lupe means that while most can hear/understand ordinary sounds/meanings, only those with elevated hearing/intellect can hear the higher sounds/messages such as a dog hears a whistle. As dog whistles have sound audible to human ears as well as the higher pitch which we don’t, so the dog hears a much more complex message from the whistle.
