Hearing aids based on digital technology have fostered the emergence of new prescription formulas for gain. There are currently two large groups of formulas: generic ones, applicable to any type of hearing aid, such as DSL or NAL-R, and specific formulas developed by manufacturers for specific models and brands of hearing aids, such as ASAII from Oticon or Phonak DIGITAL. Both groups of formulas have advantages and limitations. Specific formulas are fast and do not require great knowledge. Generic formulas, on the other hand, allow the differentiating aspects of each individual to be considered in a broad way in the final prescription of profit. In this article we review the main generic prescription prescription methods that have appeared in recent years.
