Expert Soundproof Buying Intelligence Guide
Expert Soundproof Buying Intelligence Guide
A technical decision framework for selecting acoustic enclosures based on verified testing standards, not marketing claims or surface-level ratings.
Evidence Over Claims
Ask for independent external test reports, not just marketing claims.Frequency Matters
Check NIC values across speech frequencies (500-4000 Hz) - this is where privacy matters most.Certified Labs Only
Verify certification body - TÜV SÜD, Intertek or SGS are trusted.Placement Reality
Consider pod placement - even A+ pods need proper layout to avoid sound reflections in open offices.Procurement
When buying pods, always ask for the independent test reports with NIC values, not just “A+” claims.Certification
TÜV SÜD, Intertek, SGS aretrusted labs that apply the ISO method and may assign letter grades for clarity.Decision Making
Focus on the numeric NIC result (≥30dB for top-tier privacy) rather than the marketing label.Important Industry Clarification
ISO 23351-1:2020 only defines how to measure speech level reduction. The “A+” label is an industry shorthand meaning NIC ≥30dB, but it is not part of the ISO standard itself.
To be accurate, Sound Pod™ is tested to be NIC 35dB, rather than the letter grade.
