Reference to the background noise for when Nagato is reading:
(発声练习の定番セリフ)

PANEL QUIZ ATTACK 25(パネルクイズアタック25)
Glass Mask(ガラスの仮面)
(分からず。「天ザル」は「天山」「天丼」かも)
(少年A)
Trick(トリック)
Detective Conan(名探侦コナン)
(水戸黄门)
(ベルサイユのばら)

Just direct copy and paste with some editing...don't blame me if I'm wrong...
And someone mentioned that the idea of Nagato sitting still reading with noise in background comes from evagellion, is that true?(I havn't watched evagellion)
