Answer
Hi,
thank you for your question.
Usually, parakeets like music and noise and will make a lot of  noise of their own (that's why your remote control for the TV or your stereo works on the parakeets: turn the TV louder and the birds will get louder, too ;). When they don't like it, they make an agressive sound that is easily recognizable as scolding.
Here's the sound they make (often loudly) when they feel comfortable:

Here are pictures of male and female parakeets and info on how to sex them:
