What term is commonly used to refer to someone who has a hearing threshold above the normal level?

The term "hearing impaired" is widely accepted and used to refer to individuals who experience a hearing loss that affects their ability to hear sounds at a normal level. This encompasses a range of hearing capabilities, from mild to profound hearing loss. The use of this term is common in medical contexts and in discussions about accessibility, while also being recognized by various organizations focused on hearing health.

In comparison, "sound impaired" is less commonly used and may not clearly imply a loss of hearing specifically. "Auditory disabled," though it might convey a similar meaning, does not have the same standard recognition or acceptance as "hearing impaired" in the medical and social discussions related to hearing health. Lastly, "speech impeded" refers to difficulties in producing speech, which is not directly related to hearing capabilities. Thus, "hearing impaired" is the most accurate and appropriate choice for someone who has a hearing threshold above the normal level.
