Word structure
The verb 'verstummen' (to fall silent) is derived from the adjective 'stumm' (silent/mute). The prefix 'ver-' here expresses the beginning of a state, so 'stumm werden' (to become silent).
EXAMPLE

The music suddenly fell silent.
Perfect tense with 'sein'
The perfect tense of 'verstummen' (to fall silent) is always formed with the auxiliary verb 'sein'. The reason is that it describes a change of state (from loud to quiet).
EXAMPLE
Nach seiner Rede sind alle Kritiker verstummt.
After his speech, all the critics fell silent.
Context clue
You can recognize the figurative meaning from the subject. If it is a concrete source of noise (person, engine, music), the literal meaning is intended. If it is something abstract (criticism, rumors, protest), the figurative meaning is intended.
EXAMPLE
