What kind of hearing loss may be indicated by a threshold greater than 90 dB?

A threshold greater than 90 dB typically indicates profound hearing loss. This classification suggests that the individual has a significant degree of auditory impairment and may struggle to hear sounds even at very high volumes. In practical terms, people with profound hearing loss often cannot hear sounds in the normal conversational range and may rely on visual cues or assistive listening devices to communicate effectively.

The concept of hearing thresholds is essential in audiology, as it helps professionals determine the degree of hearing loss and tailor appropriate interventions, such as hearing aids or cochlear implants. A threshold of over 90 dB falls well outside the range for moderate, severe, or even moderate to severe hearing loss, which are categorized at lower thresholds.
