Metrics
Earplug performance is evaluated via perceptual models that have been shown to predict human judgements of loudness and sound quality.
| Metric | What it Measures |
|---|---|
| Perceptual Loudness Reduction | How much quieter the environment sounds |
| Perceptual Sound Quality | How natural the sound remains |
| SoundScore & SoundGrade | Weighted composite and letter grade |
Note
We recognize that additional non-audio dimensions (e.g., comfort, style, durability) are important to consumers, but are not considered in these metrics.
