Bedrock Elite i10 — Advanced Class 1 Acoustic Analyzer with Full STI & STIPA Measurement
The Bedrock Elite i10 is the most advanced professional Class 1 acoustic analyzer available. It is the only instrument in the world capable of measuring Full Speech Transmission Index (Full STI) in under 60 seconds — making comprehensive speech intelligibility measurement practical in the field for the first time. Every measurement module is included. No firmware gates. No unlock fees. Ships as a complete kit ready to measure from day one.
Traditional Full STI measurement using 98 modulation frequencies across 7 octave bands typically takes 10–15 minutes per measurement position. In a large building with dozens of measurement positions, this makes Full STI impractical for field use — which is why most engineers resort to STIPA (a 14-frequency approximation) instead. The i10 changes this: it delivers the same 98-modulation-frequency Full STI measurement in under 60 seconds, without any compromise in measurement accuracy.
Key Measurement Capabilities
Full STI (Speech Transmission Index) — complete IEC 60268-16 compliant STI measurement using 98 modulation frequencies in under 60 seconds (only instrument in the world capable of this)
STIPA — fast speech intelligibility measurement for voice alarm and PA/GA system commissioning per IEC 60268-16
Sound level metering — A, C, Z weightings; Fast, Slow, Impulse time constants; Lmax, Lmin, Leq, SEL, LAeq, LCeq, LZeq
Real-time 1/1 octave and 1/3 octave band analysis (RTA) — simultaneous measurement across all bands
Dual-channel FFT analysis — frequency response, transfer function, phase, coherence measurement
Reverberation time (RT60) — EDT, T10, T20, T30 per ISO 3382-1 and ISO 3382-2
Data logging — long-term unattended measurements with time-stamped records
GPS position tagging — for georeferenced noise mapping and environmental surveys
Building acoustics — airborne and impact sound insulation per ISO 16283, facade measurements
Technical Specifications

Frequently Asked Questions
What makes the i10 different from other Class 1 sound level meters?
The i10 is the only instrument that measures Full STI (not just STIPA) in under 60 seconds. All other manufacturers either do not support Full STI measurement at all, or require 10–15 minutes for a complete Full STI measurement — making it impractical in the field. Combined with every other measurement module included at no extra cost, the i10 is the most capable all-in-one acoustic analyzer available.
Are all measurement modules really included?
Yes. Every i10 ships with all modules fully unlocked: sound level metering, Full STI, STIPA, 1/1 and 1/3 octave RTA, dual-channel FFT, RT60 (EDT/T10/T20/T30), statistical analysis (Ln percentiles, Lden/Lnight), data logging, GPS, and building acoustics. No firmware gates. No unlock codes. No subscription fees of any kind.
Which talkbox works with the i10?
The i10 works with both the BTB65 Talkbox (standard output for indoor use) and the BTB115 Advanced Talkbox (115 dB SPL maximum output for large venues, stadiums, and outdoor systems).
