For educational purposes, hearing-impaired learners are classified into 4 categories. Which of these has a hearing loss range of 71-90 dB?
Detailed Explanation & Solution
📌 Core Theoretical Concept:
For educational and clinical purposes, hearing-impaired learners are classified based on their decibel (dB) hearing threshold loss. The hearing loss range of 71-90 dB specifically defines 'Severe Hearing Loss'. Children falling under this category experience immense difficulty in hearing normal conversational speech without powerful amplification, hearing aids, or specialized assistive listening devices. In an inclusive classroom environment, such learners require specific pedagogical adaptations, visual aids, speechreading support, and specialized instructional strategies to ensure optimal cognitive, social, and language development.
📊 Key Exam Points:
- Mild Hearing Loss: Ranges from 26-40 dB; students may miss faint or distant speech.
- Moderate Hearing Loss: Ranges from 41-70 dB; conversations must be loud to be understood, requiring hearing aids.
- Severe Hearing Loss: Ranges from 71-90 dB; only very loud sounds are perceived, requiring sign language or intensive speech training.
- Profound Hearing Loss: 91 dB and above; characterized by total or near-total deafness.
📖 Theoretical Reference: In Child Development and Pedagogy, understanding sensory impairments is vital for implementing Inclusive Education effectively under Right to Education frameworks and disability acts.
