• Geriatric Clothing Design Considerations:
• Physiological Factors in the Elderly:
• Elderly individuals often suffer from arthritis, reduced cervical spine mobility, and respiratory sensitivity.
• Unfavorable Features:
• Turtle neck collars: Strongly disliked because the tight elasticated high neck restricts head movement, presses on sensitive trachea/carotid sinus, and causes significant pain and difficulty when pulling garments over the head.
• Favorable Features:
• V-necklines (easy over-head donning), raglan sleeves (generous armhole clearance), and hip-length jackets.
• Conclusion: Turtle neck (Option 2).

Correct option: (2) Turtle neck

• Audiological Classification of Hearing Impairment:
• Pure-tone audiometry classification based on Hearing Threshold Level (dB HL, WHO standards):
• Mild Hearing Loss: $26 - 40\text{ dB}$
• Moderate Hearing Loss: $41 - 60\text{ dB}$
• Severe Hearing Loss: $61 - 80\text{ dB}$
• Profound Hearing Loss: $\gt 80\text{ dB}$ ($81\text{ dB}$ and above)
• Evaluation: An individual with profound hearing loss cannot detect sounds below 80 dB, requiring high-power amplification or cochlear implants.
• Conclusion: 80 dB (Option 1).

Correct option: (1) 80 dB
