CLASS 1 MEASURING INSTRUMENT

COMPREHENSIVE MODULE LIST

Applicable to a broad range of applications, the Bedrock i9 is a class 1/type 1 acoustic measuring device. This instrument is the first choice for precise and trustworthy acoustic measurements because of its premium 1/2″ prepolarized microphone capsule. While meeting class 1 requirements (IEC 616272) for sound level meters, the Bedrock i9 also provides a range of additional features.

• STIPA measuring (quick screening mode, pro mode, averaging mode)
• Full STI using the direct method (65 second measurement).
• Speech Level Measurements cf IEC-60268 Annex J. 
• Class 1 / Type 1 sound level meter (fast, slow, impulse; A/C.Z-weighting, Leq, SEL) conforming to IEC-61672 class 1, ANSI S1.4 Type 1.
• Statistical acoustics (L10, L90, etc)
• Real Time Analyzer (1/12, 1/6, 1/3 and 1/1 octave)
• FFT analyzer (detailed frequency analysis up to 32768 lines)
• RT60 measuring (reverberation times: T20/T30/EDT).
• Noise Curves (NR, NC, PNC, NCB, RC, RC mark II)
• THD+N With firmware 2.6
• Fundamental frequency estimation With firmware 2.6
• Building acoustics: D, R’, DnT, Dn With firmware 2.6
• Building acoustics: SRI/STC. With firmware 2.6
• Audio oscilloscope 
• Long term logging and monitoring (LEQ, RTA)
• AC Volt meter for audio line level measurements (dBU, dBV, V rms)
• Calibrated audio recording
• USB audio device mode – calibrated audio for your PC-based software applications
• More functionality will be added through free future firmware upgrades.

The Bedrock i9 and the tried-and-true Bedrock i5 share the same primary platform. All throughout, though, the i9 has been engineered and tested to meet class 1 standards. Its detachable microphone capsule is compatible with the majority of popular high-end UNC capsule types made by different producers.

For those who demand the highest levels of precision and efficiency, the Bedrock i9 is a versatile measuring solution. This, along with its affordable price, makes the Bedrock i9 a desirable addition to any consultant’s or acoustician’s toolkit.
