What is the passage mainly about?

The sound you are ignoring is still being checked for things that matter. (The passage sets up a puzzle, uses the study as evidence, and answers it in the last paragraph: something keeps reading the ignored side.)

According to the passage, what could Cherry's listeners report about the ignored ear?

Almost nothing: not the topic and not the words. (The passage says they could report almost nothing, and then names both things they missed. The name result came from a later study.)

In this passage, a "channel" is

one stream of sound among several you could listen to (The word arrives right after an experiment with two recordings and two ears, and it is the one being ignored. It names a stream of sound.)

The passage suggests that attention works less like a door and more like

a filter that keeps checking whatever it lets past (A shut door would block the name and an open one would flood you. What is left is something that lets most through unread but still watches it.)

Your Name in a Loud Room: Level 2 Reading Comprehension Questions

At a crowded party you can follow one voice and let the rest of the room become noise. It feels like closing a door. Then someone across the room says your name, and you hear it.

Both of those are true, and together they say something odd about attention. If the door were really shut, your name could not get through. If it were open, you would be flooded.

A researcher named Colin Cherry tested this in the 1950s. He played two different recordings, one into each ear, and asked people to repeat one of them aloud as it went. They managed it. Afterwards they could report almost nothing about the ignored ear: not the topic, not the words. But in a later study built on his method, about a third of listeners noticed their own name when it was slipped into the ear they were ignoring.

So the ignored channel is not switched off. Something keeps reading all of it, cheaply and without your knowledge, and interrupts you when it finds something that matters.
