I am sorry, but the provided text is a 510(k) clearance letter from the FDA for a device called "Whistle Watch." It states that the device is substantially equivalent to legally marketed predicate devices and can therefore be marketed.
However, this document does not contain any information about acceptance criteria, device performance studies, sample sizes, expert qualifications, or ground truth establishment. It is a regulatory approval document, not a study report.
Therefore, I cannot fulfill your request to describe the acceptance criteria and the study that proves the device meets them based on the given input.
