This sounds like a good idea but it might be counterproductive. If you’re using this for standardizing your pauses it’ll definitely help. But you’ll probably also be paying attention to the sounds instead of paying attention to the position of your body during the pause. This would be more critical if the pause is somewhere in the middle of the range of motion. You’re not just pausing for the sake of pausing. You should be actively trying to improve your form at important points in the ROM.
