including:<\/p>\n\n\n\n<ul><li>Proof of unintelligible speech index scores (CIS) in secure areas such as SCIF and SAPF areas (privacy applications)<\/li><li>Proof of effectiveness of white noise systems for noise masking systems in secure areas such as SCIF and SAPF areas (privacy applications)<\/li><li>Verification of speech intelligibility for evacuation systems (fire and emergency) both indoor and outdoor<\/li><li>Verification of speech intelligibility for conference rooms, classrooms, and auditoriums<\/li><\/ul>\n\n\n\n<p>Speech intelligibility may be reported using two alternative measurement scales which are:<\/p>\n\n\n\n<ul><li>CIS (Common Intelligibility Scale) &#8211; which is used for government and military applications<\/li><li>STI (Speech Transmission Index) &#8211; which is used for most other applications<\/li><\/ul>\n\n\n\n<p>Both methods of speech intelligibility testing involve using pre-recorded sounds which are then amplified and measured within the room, or in adjacent spaces (for privacy applications).<\/p>\n\n\n\n<p>We utilize industry standard equipment from Liechtenstein-based  manufacturer NTI to conduct this testing.<\/p>\n\n\n\n<hr
