Bedrock Intelligibility Measurement Kit

This kit contains all you need for speech intelligibility measurements using the STIPA method according to most national and international standards, including the following:

• IEC-60268-16
• ISO-7240-19
• NFPA72 Annex D
• NEN2575
• DIN-60849/DIN-VDE-0833-4
• BS-5839-8

The kit consists of a Bedrock meter (AM100, SM90, SM50) and a Bedrock TalkBox (BTB115,  BTB65), combined in a rugged waterproof carrying case.

The functionality extends far beyond just STIPA measurements, and covers all of the most commonly required acoustic test methods:

• STIPA measuring (quick screening mode, pro mode).
• Full STI using the direct method (65 second measurement).
• Speech Level Measurements cf IEC-60268 Annex J.
• AM100/SM90:  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.
• SM50: Class 2 / Type 2 sound level meter (fast, slow, A/C.Z-weighting, Leq) conforming to IEC-61672 class 1, ANSI S1.4 Type 1.
• 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.
• Fundamental frequency estimation.
• Building acoustics: D, R', DnT, Dn.
• Building acoustics: SRI/STC. 
• AM100: OSHA/TWA/ISO noise exposure
• Calibrated audio recording.
• LAeq long-term logging and monitoring (LEQ, RTA).
• Audio oscilloscope.
• AC Volt meter for audio line level measurements (dBU, dBV, V rms).
• USB audio device mode - calibrated audio for your PC-based software applications.
• More functionality will be added through free future firmware upgrades.
