Jeremy Loffredo is an American journalist who was recently held behind bars by "Israel" for 4 days for doing his job. He wrote today:

According to Addameer, a prisoner rights NGO based in Ramallah, one form of “duel torture” used at the Al Moscobiyeh interrogation center [where I was held in solitary confinement for committing journalism] involves deliberately moving a prisoner to the cell next to another security detainee and torturing them. The intention is to subject the detainee to the sounds of their fellow inmate’s screams and cries, amplifying their psychological torment.
On October 11th, despite an Israeli court order for my release, I was returned to my solitary confinement cell without explanation. Shortly after, a Palestinian prisoner was deliberately placed in the cell next to mine and subjected to brutal torture for approximately three hours.
The sounds of his screams and cries filled my cell — an inescapable reminder of the incredible cruelty being inflicted just beyond my reach. When the noise finally stopped, two intelligence officers came to my cell and transported me to a military base in the West Bank for interrogation.
After learning that this is an unofficial method of torture and torment, it’s clear to me that the intent was to instill fear before my interrogation, to pressure me into a confession or an admission of guilt.
