Audifiers and hearing aids are different types of hearing technology. They are both used to remap sound to a person's hearing range, but generally differ in purpose and power.
Audifiers reduce listening effort, freeing up valuable mental resources for memory and concentration, and generally make more challenging listening situations more pleasurable.
They can also greatly reduce the risk of mishearing.
Hearing aids are generally used by individuals who would not be able to hear speech at normal conversational levels without the ‘aid’ of such devices.
Hearing aids therefore have a tremendous impact on quality of life and psychosocial wellbeing for those who use them.
