ELI5: Why do sounds like the letter "S", "ts" and drums/cymbals sound extra static-y on the radio, even on clear stations?

They contain high-frequency components. Radio stations use 10-15 KHz audio bandwith.  This is quite sufficient to transmit low and midrange sounds, and even most "high" frequency pitches that humans can perceive.  But some sounds contain high frequency components in the 15-20 KHz range, and radio transmitters/receivers are simply not made to handle them well (or at all).
