Noisy
Picky
い adjective
You can guess this is an adjective from the い at the end. The meaning for the kanji is noisy and picky, so the adjective version is also noisy and picky.
This type of noisy can be just about being noisy, like a group of turkeys. It can also be a ""picky"" sort of noisy, when someone is being particular in a vocal sort of way.
