Unbalance & high impedence signals can be disrupted

Magnetic fields caused by ESD into a metal enclosure can induce currents into nearby PCB tracks & cables.

ESD Voltage transients can be capacitively coupled to PCB  tracks.

RF can cause some circuits to become saturated or for bias levels to be incorrect

Audio Amplifier Non Linearity at high frequencies can cause audible artifacts
