During the battle with Grendel, the poet uses sound imagery to intensify the scene and create a more vivid picture in the reader's mind.
Some specific examples of sound imagery include:
The "terrifying shrieks of pain and defeat" as Grendel's arm is torn off by Beowulf's mighty strokes
The "tears torn out of Grendel's taut throat" as Beowulf's sword cuts through him
The "sword that Beowulf brings into the battle with Grendel's mother" being "tossed aside, angry; the steel-edged blade lay where he had dropped it".
The "blood-soaked" sword that melts in Grendel's mother's blood, with "dripping-down like water"
These vivid descriptions of the battle between Beowulf and Grendel help to create a more immersive experience for the reader, allowing them to visualize the intense and gruesome events taking place.
