For calculating the Speech Transmission Index, STIPA has emerged as the industry standard. The Bedrock i5 STIPA meter is the tool that many have been waiting for: at last, an accurate, dependable, and reasonably priced STIPA meter! Created from the ground up by the same team that created STIPA and worked on the Speech Transmission Index for the previous few decades.

With its full-color touch screen, the i5 is simple to use and comprehend, even for those who are unfamiliar with the Speech Transmission Index. The typical STI user won’t have to deal with challenging key combinations, difficult calibration processes, or other annoyances associated with STI measurement equipment. On the other hand, the i5 is nearly plug-and-play simple to operate. In addition, even the most seasoned STI specialists will discover every feature they could possibly want.

The Speech Transmission Index measuring device, i5, was created by the creators of STIPA and is fully compliant with IEC-60268-16, 4th ed. (2011) specifications. There are two STIPA measuring modes available: a quick screening mode that is designed to be user-friendly and quick, and a “Pro” mode that provides the most comprehensive and adaptable functionality of any Speech Transmission Index measurement available to date.

The i5 is also a real-time analyzer and class 2 sound level meter that complies fully with regulations. This may be the only acoustic measuring instrument you’ll ever need because the Bedrock i5 has all the features.
