H3: the investigation by ge healthcare has been completed.The acoustic performance of the scanner was tested, and it was found to be within regulatory limits.No system issue was found.It is the customers responsibility to provide hearing protection for the patients with a noise reduction rating (nrr) of greater than 29 db as described in the operator manual.The patient was provided hearing protection; however, it was inadequate to protect them from the acoustic noise.Ge reviewed the recommended hearing protection as stated in the operator manual with the customer.No corrections are required as the system was operating within specification.The root cause appears to be inadequate hearing protection.
