Here are video clips of the references 3979J, 5078P and 5016R minute repeaters from Patek Philippe. These are not showroom watches, they are owned by collectors who have worn them. The 3979 is a couple of years old while the 5078 and 5016 are fairly new.
Although the videos were filmed at the same place at the same time, save for the third clip of the 5016, it would not be fair to compare the chiming, except very generally, because of differences in ambient noise (cars going by) or closeness to the camera/microphone.
