When we sailed on Oasis immediately after the amplification, the music on deck 17 was unbearable. It was also unbelievably loud in Central Park. We complained to our Genie who came up to the suite to check it out. She brought the Cruise Director with her and they both agreed that it was unsat. Some time later that day, they did something...not quite sure what it was...but the noise level came down considerably. Still too loud for my taste but waaay better than it had been. Not sure if the "fix" was a permanent one or if they just did it to appease us on that one cruise.
