Why isn’t single-sided deafness considered a “benchmark disability” when it’s clearly socially disabling?
I’m trying to understand the logic here. In many systems (like in India under the Rights of Persons with Disabilities Act, 2016), “benchmark disability” usually requires ≥40% impairment. But single-sided deafness (SSD) often doesn’t meet that threshold on paper—despite causing real-world difficulties.
From what I understand, disability assessment for hearing is largely based on bilateral hearing loss (both ears). So if one ear is normal, the calculated percentage may fall below 40%, even if the person struggles a lot functionally.
But in reality, SSD can be quite disabling:
You lose sound localization (can’t tell where sounds are coming from)
Hearing in noisy environments becomes very difficult
Conversations in groups are exhausting and often missed
Safety issues (e.g., traffic, alarms, someone calling from one side)
Social fatigue and isolation because communication takes extra effort
So it feels like a mismatch between “measured impairment” vs “lived disability.”
Is the system outdated or too rigid in focusing on percentages rather than functional impact?
Should SSD be reconsidered under benchmark disability, especially for accommodations?
Curious to hear thoughts from people with SSD, doctors, and anyone familiar with disability certification systems.
