Disclosed herein are methods for determining a location of a hearing aid, performed by an electronic device having a processor, a memory, and interface circuitry. The method includes obtaining first accelerometer data from a hearing aid. The method includes obtaining second accelerometer data from the electronic device. The method includes determining, based on the first accelerometer data and the second accelerometer data, an acceleration parameter indicative of a difference between the first accelerometer data and the second accelerometer data. In accordance with the acceleration parameter meeting a safety criterion, the method includes generating lost control data and outputting the lost control data to the hearing aid.
