Which action is prohibited for unlicensed hearing aid fitters?

Fitting hearing aids for consumers is a regulated activity that requires appropriate licensing and training in North Carolina. This regulation is in place to ensure that individuals receiving hearing aids are assessed and fitted by professionals who meet the necessary educational and ethical standards. Fitting hearing aids involves not only the selection of the device but also the precise adjustments and calibrations needed to ensure optimal performance for the consumer's specific hearing loss.

Without a license, an individual lacks the required knowledge and competency to perform fittings safely and effectively, which is why this action is explicitly prohibited. The other activities listed, while they may involve some level of expertise and care, do not directly involve the technical fitting process and may have different regulatory considerations, making them less strictly regulated compared to the act of fitting hearing aids itself.
