What term refers to metrics based on extensive research developed to highly correlate with human response?

• A. Cumulative metrics
• B. Response indices
• C. Loudness models
• D. Subjective scales

Answer: (A)

When metrics are described as being developed through extensive research and shown to correlate highly with human response, they are referring to measures that have been built up from large datasets and validated across many studies to reflect how people actually perceive or react. This idea of evidence accumulated from multiple experiments gives the metric robustness and alignment with human experience, which is captured by the term cumulative metrics.

Subjective scales are based on direct human judgments themselves, so they aren’t about a broader, research-backed metric that’s been validated across conditions. Loudness models focus on predicting a specific perceptual attribute (loudness) rather than a broad set of metrics that align with overall human responses. Response indices imply particular response measures but don’t inherently convey the sense of being derived from wide-reaching empirical validation across many studies.
