When performing a listening check, what does barely audible static at low volume indicate?

Barely audible static at low volume during a listening check is typically indicative of normal circuit noise in hearing aids. All electronic devices, including hearing aids, can generate some level of background noise due to the presence of circuits and components actively processing sound. This noise is generally minimal and not disruptive to the overall performance of the device.

When the volume is set low and you hear a slight static, it doesn’t usually point to any malfunction or defect; rather, it signifies that the device is functioning within its expected parameters. Any noticeable change in this noise level at different volume settings or when the device is not functioning correctly would require further investigation, but a small amount of static at low volumes is commonplace.

Issues like a low battery or a defective earmold would typically present with more prominent symptoms such as distorted sound quality or a complete loss of signal, rather than just a minor background noise.
