Dramatic moans voiced with microphone (7)
I believe the answer is:
seismic
'dramatic moans voiced with microphone' is the definition.
I can't judge whether this defines the answer.
'voiced with microphone' is the wordplay.
'voiced with' becomes 'seis' (I can't explain this - if you can you should give a lot more credence to this answer).
'microphone' becomes 'mic'.
'seis'+'mic'='SEISMIC'
Can you help me to learn more?
(Other definitions for seismic that I've seen before include "earth-shattering effects?" , "of enormous proportions" , "like tremors?" , "Earthshaking" , "Resulting from earthquakes" .)
