That type of music is used to torture people into submission, and goes by the name “music torture”.
It’s used to drive the victims insane, and is designed to destabilize their mind to make them controllable.
Here’s a quote from a person who was subjected to this:
British citizen
Ruhal Ahmed described the process in a 2008 interview with Reprieve investigators: "I can bear being beaten up, it's not a problem. Once you accept that you're going to go into the interrogation room and be beaten up, it's fine. You can prepare yourself mentally. But when you're being psychologically tortured, you can't."
He said he had been exposed to the torture "
numerous times" to a variety of music. "It makes you feel like you are going mad. You lose the plot, and it's very scary to think that you might go crazy because of all the music,
because of the loud noise and because after a while you don't hear the lyrics at all, all you hear is heavy banging."

I heard this nonstop over and over," he reportedly told Clive Stafford Smith, his lawyer and the founder and director of
Reprieve, a U.K-based organization determined to end music torture practices. "
The CIA worked on people, including me, day and night for the months before I left. Plenty lost their minds."
Mohamed said he could hear
others in the prison "screaming and smashing their heads against walls."
