In the domain of sound reproduction (as opposed to inebriation), hangover is the tendency of a loudspeaker cone to continue moving after reproducing a sound, or especially, a transient (see WFTD archive transient). This is both a low frequency and high frequency phenomenon, and can only be reduced by adding damping to the system. One way of doing this is to increase the damping factor (see WFTD archive damping factor) of the amplifier.
