Field Comparison Study: Agreement Between Soundtrace Audiograms and Prior Vendor Audiograms

5,961 employees. 116 employers. 225+ devices. 280+ test administrators.

This study examined how audiograms performed using the Soundtrace system compared to historical audiograms from external occupational hearing testing providers. With 4,988 valid matched comparisons across 116 employers, Soundtrace results showed ~97% agreement within ±10 dB and a mean PTA difference of just –2.42 dB — fully within published clinical benchmarks.

The Hidden Cost of Untreated Hearing Loss: Dementia, Heart Disease, and Beyond

Why OSHA compliance is the floor - not the ceiling.

A comprehensive review of peer-reviewed research linking untreated occupational hearing loss to cognitive decline, cardiovascular disease, workplace injuries, and depression. Makes the case for preventive hearing conservation that goes beyond minimum compliance.

5× higher dementia risk with untreated hearing loss
48% increased cardiovascular disease risk
3× more workplace injuries among hearing-impaired workers

Replacing the Mobile Van: ROI Analysis of In-House Audiometric Testing

How companies are cutting costs and improving compliance with year-round testing.

A detailed cost comparison of traditional mobile van audiometric testing vs. Soundtrace's in-house model. Includes case study data from manufacturing, construction, and logistics companies showing 40-60% cost reductions and dramatically improved compliance rates.

Unprotected by Design: The Hidden Data Security Risk Inside Occupational Health Programs

Why audiometric records held without HIPAA BAAs or SOC 2 expose employers to liability.

41% of 2023 healthcare data breaches originated from third-party vendors. This paper examines why employers who never asked their audiometric testing vendor about data security are already exposed - regulatory frameworks, breach statistics, vendor due diligence checklists, and what a secure cloud-native platform actually looks like.

The Silent Liability: How Occupational Hearing Loss Claims Are Quietly Compounding Your Workers' Compensation Exposure

A financial risk analysis for risk managers, CFOs, and occupational health directors.

Occupational hearing loss is the most prevalent work-related condition in the U.S., yet it remains the least visible workers' comp line item. Claims surface 10–15 years after exposure — often after records have been destroyed. This paper quantifies the financial exposure building silently inside noise-exposed workforces and presents a longitudinal audiometric data strategy for liability containment.

68% of claims lack documentation to contest at settlement
