Mach diamonds.. Delta IV Heavy launches have great ones.. the rare Atlas V launch with no strap-on solid boosters are pretty good too.

Titan 2 engines shrieked at startup, for example. Rocketdyne Atlas made a low rumble thunder crackle sound that changed pitch as it rose due to Doppler effect. I witnessed the first aborted launch attempt of Discovery, back in 1984, when I heard the super-odd burp-whomp-shriek-whomp sound of SSMEs starting and aborting. Weird! And, of course, the sound always lags what you see by several seconds, which is also weird. Adding to the strangeness is the feeling of the ground moving beneath your feet shortly *before* the sound arrives. Weird! - Ed Kyle
