beeps是什么意思？

If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps, and ask for directions from a human.

Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed of the same tone and irregular beeps of a different tone during the night.

She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones.
