The Bedrock i5 STIPA meter offers a reliable and cost-effective solution for accurately measuring the Speech Transmission Index (STI). It was developed by the innovators behind the original STIPA and the STI concept, ensuring its design adheres to longstanding industry standards. Equipped with a full-color touch screen, the i5 simplifies the user experience by eliminating complex calibrations and operations, making it accessible even to novices in STI measurements. For seasoned professionals, the i5 includes advanced features to meet comprehensive measurement needs. It offers two distinct STI measurement modes: a quick mode optimized for efficiency and ease of use, and a professional mode that provides an extensive array of functionalities. Compliant with IEC-60268-16, the i5 is not only an STI tool but also functions as a real-time analyzer and a class 2 sound level meter, providing an all-encompassing acoustic measurement solution within a rugged, waterproof design.
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.
