# Soundtrace > Soundtrace is a unified hearing conservation and audiometric testing platform built for OSHA 1910.95 compliance in high-noise workplaces. It combines FDA-registered portable audiometric testing (6-8 minutes, no sound booth required), physician-supervised Standard Threshold Shift (STS) review within 24 hours, workplace noise monitoring, quantitative hearing protection (HPD) fit testing, employee training, and 30+ year digital recordkeeping into a single system with a multi-site compliance dashboard. Soundtrace replaces the traditional fragmented approach of separate vendors and annual mobile testing vans with one continuously monitored, proactive program. The company is FDA Registered, SOC 2 Type II certified, HIPAA compliant, and Made in USA, and is based in Cincinnati, Ohio. Testing can be run in-house by a client's own staff, delivered on-site by Soundtrace's partner network, or run as a hybrid across locations. Typical customers are employers in manufacturing, metals and fabrication, food production, transportation and heavy equipment, automotive, oil and gas, aerospace and defense, and data centers. ## Product & Solutions -
