Noise figures are meaningful only with their measurement conditions. Ask which mode and attachment were tested, and avoid treating an undocumented quiet claim as a guarantee.
What to check
| Check | What to verify |
|---|---|
| Figure | Record the stated unit and conditions. |
| Mode | Match normal intended use. |
| Trial | Check return terms if household fit is uncertain. |

Before you decide
Keep the dog elsewhere during unfamiliar equipment use rather than testing tolerance by force.
