Sense: adjective/1
'Louder' and 'noisier' both describe increased sound, but 'noisier' carries a more negative feeling — it suggests unwanted or unpleasant sound, while 'louder' can be neutral (a louder speaker system). 'More deafening' is much stronger and implies the sound is almost painfully intense, often used for dramatic effect. 'More thunderous' specifically describes low, rumbling sounds like thunder or applause, whereas 'louder' covers all types of sound. For example: the traffic was noisier at rush hour (annoying sound), the crowd's response grew louder and louder (neutral volume increase), and the thunderous roar of the waterfall was more deafening up close (dramatic intensity).

Etymology
'Louder' is the comparative form of 'loud', which comes from Old English 'hlūd', meaning 'making a loud noise'. The word traces back through Proto-Germanic '*hlūdaz' to the Proto-Indo-European root '*kleu-', meaning 'to hear'. Related words appear in Old High German ('hlūt'), Old Norse ('hljóðr'), and modern German ('laut').
