How is hearing loss classified according to severity?

The classification of hearing loss according to severity is a well-established framework that helps audiologists and healthcare professionals describe and assess the extent of an individual's hearing impairment. The correct answer provides a comprehensive range of categories that reflect the varying degrees of hearing loss, allowing for a nuanced understanding of an individual's auditory capabilities.

Specifically, the categories of normal, mild, moderate, moderately severe, severe, and profound encompass the full spectrum of hearing ability, from those who can hear normally to individuals with significant hearing challenges. This classification typically follows the threshold levels of hearing (measured in decibels), where each degree corresponds to the severity of loss.

For instance:

• Normal hearing generally refers to thresholds of 0-25 dB.

• Mild hearing loss ranges from 26-40 dB, where sounds may be soft or difficult to hear.

• Moderate loss (41-55 dB) indicates a more notable difficulty in hearing everyday sounds.

• Moderately severe (56-70 dB) shows that many sounds, especially softer ones, are often inaudible.

• Severe loss (71-90 dB) significantly impacts communication, even with amplification.

• Profound hearing loss (91 dB and above) means that hearing is very limited
