What is a reason hearing-impaired children have worse speech recognition with more RT even when aided?

• A. RT Has No Effect
• B. Device Processing Delays
• C. Longer RT Improves SNR
• D. Hearing Aids Boost Noise

Answer: (B)

Processing delays in hearing devices can make timing become the bottleneck for understanding speech in noise. When the microphone input is amplified but the output is delayed, the speech signal that the listener hears is not synchronously aligned with the surrounding noise and with the listener’s rapid auditory processing. This temporal mismatch disrupts how the brain separates speech from noise and extracts fast phonetic cues. For children with hearing loss, who already rely heavily on tight timing cues to decode speech, longer device latency hurts intelligibility even when amplification is provided. The other ideas don’t capture this timing issue: simply saying the latency has no effect ignores how crucial precise timing is for speech perception, longer latency does not improve the signal-to-noise ratio, and the notion that hearing aids “boost noise” doesn’t address the delay’s impact on processing as speech unfolds.
