Inside the X-Comfort Minipod Quiet: Teardown, Decibel Proof, and Interior Walkthrough
By James H. Sterling
Meeting ISO 23351-1 standards for speech privacy requires more than just stopping background racket; it requires speech privacy level attenuation ($D_{S,A}$) high enough that sensitive words cannot be recognized from nearby desks. Total silence is unnecessary. What matters is speech intelligibility.
During our exterior meter tests, a speaker read aloud from an financial audit report inside the pod at 68 dBA. Standing one meter away in an active office with 55 dBA background noise, an observer could tell someone was talking, but individual syllables and sensitive numbers were entirely unintelligible. At two meters away, the vocal sound fell below the ambient office noise floor, rendering the speaker completely silent to colleagues.
This level of background noise attenuation prevents eavesdropping without requiring double-wall masonry construction. For facilities managers, placing two MiniPods side by side allows confidential simultaneous HR and executive interviews without acoustic bleed between booths.
