UNSPSC 46191512: Sound field detecting device

A sensor that creates a sound field by generating sound in a space and detects whether a fire or intrusion occurs through the analysis of the pattern of the change in the sound field as the temperature changes

UNSPSC 46191512 Sound field detecting device is a Commodity code that, based on recent state and local solicitation activity, does not align with its nominal scope. Klein Independent School District (Klein ISD) in Harris County, Texas posted RFP #26-101 on April 17, 2026, with a June 5, 2026, response deadline for Career Technical Education (CTE) and Advanced Academics instructional resources, products, materials, equipment, memberships, and related services across 17 CTE program areas including agricultural science, architecture and construction, arts and communications, barbering and cosmetology, business and finance, criminal justice, health sciences, hospitality, information technology, manufacturing and robotics, welding, ROTC, and transportation. The procurement scope encompasses instructional supplies and materials, dual credit materials, STEM enrichment resources, test preparation materials, technology software and equipment, textbooks, and specialized equipment — none of which are sound field detecting devices. Klein ISD is a school district; the only recent activity visible under this code does not reflect the commodity's actual market.

The code shows minimal relevant recent procurement activity. Klein ISD's solicitation, while posted under this UNSPSC number, targets educational instructional materials and equipment rather than acoustic or sound detection products. Without additional opportunities in the dataset that reflect genuine demand for sound field detecting devices from state and local governments, the code cannot be characterized by geographic concentration, issuing-body mix, or representative market activity. Any pursuit strategy under this code should verify whether state and local governments actually solicit sound field detection equipment independently, or whether the code is persistently misapplied to unrelated categories.
