The biggest challenge in carrying out this experiment is the construction of the sound isolating patient hotel. This has to be like a prison, walls covered with mattressses with no possibility to make a phone call or escape the room for two weeks. Food has to be served through a hole in the door on rubber plates with rubber forks. It certainly requires a very excentric scientist with very good economical conditions (to build the hotel and recruit test persons with tinnitus) to carry out such an experiment. Hence this will likely take a very long time despite the idea is so simple. Probably it will not be done before 2098.
