The kroo-kroo-kroo of the metal spoon on the pot is described as intrusive. What does this mean?

Since the surrounding of the characters was very quite and silence prevailed hence this sound acted like an intrusive.

Explanation:

This question is regarding the interesting story called Discovering The Voice. Aunty Ifeoma is one of the main characters of this story. The sound Kroo Kroo Kroo was made as she started scraping the bottom of the dirty burnt pot.

Since at this point in the story, everyone was quiet and silence was portrayed by the author in a very delicate manner this act of scarping made sounds of intrusion.  

The other main characters Amaka and Papa-Nnukwu spoke to each other in a very low tone as well.

Explanation:

For Georgiana: It was about the flaws each and every individual has. No one is perfect, even though some may say the "yes, I'm perfect and so are you!" so and so. No! For Georgiana, it was a symbol of being human, for being who she was, and not for anyone else. The birthmark meant that she was special and unique in her own way.

For Aylmer: It simply meant about perfection and greed. He was blinded by perfection and the comments of others that made him so obsessed with the word 'perfect' and 'beautiful', that he went to extreme lengths to make that happen, not knowing it would affect him and Georgiana greatly later on. He was blinded by greed. He had Georgiana, no one else did. So, why not make it more? Why not create and transform her into someone who she wasn't. Without the birthmark, Georgiana was simply not Georgiana. She was another person, someone whole new different that Alymer created.

hope this helped!
