Power is the first thing to confirm because nothing will work if the device isn’t getting power. A dead or poorly seated battery is by far the most common reason a hearing aid produces no sound. Start by checking that a fresh battery is being used, that it’s inserted correctly with the proper orientation, and that the battery door closes securely so the contacts connect. If possible, swap in a known-good battery and ensure the device indicates it has power (some models show a light or a tone when the battery is good). Only after ruling out the battery should you move on to other potential causes like the microphone, wax guard, or volume settings.
