UNSPSC 46181902: Acoustic ear muffs or defenders

A type of hearing protection device, also known as an HPD, worn in or over the ears while exposed to hazardous noise to protect against noise-induced hearing loss. HPDs reduce (not eliminate) the level of the noise entering the ear. HPDs can also protect against other effects of noise exposure such as tinnitus and hyperacusis.

UNSPSC 46181902 Acoustic ear muffs or defenders is a Commodity code showing minimal recent state and local procurement activity aligned with its nominal scope. The single recent opportunity in the source — Temple Independent School District RFP 006-27, posted September 1, 2026 with proposals due October 6, 2026 — solicits apparel and accessories including custom screen printing and embroidery services, not hearing protection. The mismatch between the code's title and the actual solicitation suggests that either the opportunity was misclassified or the code is not actively used by state and local governments for its stated product line.

The available evidence does not support a characterization of issuing-body mix, geographic concentration, or pipeline activity under this code. No recent opportunities for acoustic ear muffs or defenders appear in the source. If your firm pursues hearing protection contracts with state or local governments, this code warrants direct verification against current procurement portals and cooperative purchasing catalogs to assess whether it remains an active classification for the product category.
