Tremetrics

What Tremetrics does

Tremetrics, founded in 1962 and headquartered in Eden Prairie, Minnesota, manufactures medical devices for occupational hearing testing. The company designs audiometers, sound booths, and hearing conservation software for health and safety professionals, occupational health clinics, and mobile testing companies operating under OSHA workplace hearing conservation programs. Tremetrics operates as a US subsidiary of Demant, a Danish hearing healthcare group, with 11-50 employees and is privately held.

The product portfolio centers on the RA660 and RA360 occupational audiometers, the AR993 sound booth, the Oscar 360, a Real-Time Octave Band Monitor, and the HearCon database software. Underlying technology includes a proprietary Bio-Acoustic Simulator for verifying audiometer fidelity, active noise reduction (ANR), digital speech discrimination assessment, and integration with leading occupational health record platforms such as Hear/Trak, OHM, and Cority. The company holds ISO 13485 certification for medical device quality management, HIPAA compliance for protected health information, Health Canada licensing, and OSHA/ANSI S3.1-1999 conformance.

The business model is B2B and channel-led, with sales through certified resellers and distributors across all 50 US states and Canada. Pricing follows quote-based, multi-year enterprise contracts rather than disclosed list pricing, with a government and direct enterprise sales channel supplementing reseller revenue. Customer segments are diversified across industrial in-house safety teams, third-party occupational clinics, and mobile testing services.

Core offering

Tremetrics designs and manufactures a complete line of OSHA-compliant audiometric testing equipment for occupational health professionals, including the RA660 and RA360 PC-based audiometers and the AR993 portable sound booth. The portfolio also includes the proprietary HearCon Software Package for hearing conservation workflow and database management, supporting on-site workplace testing, clinical hearing programs, and mobile testing operations.

Product overview

Tremetrics offers a unified product portfolio of OSHA-compliant hearing test devices for occupational health professionals. The core product line consists of three main audiometric devices: the RA660 (high-capacity PC-based audiometer for testing up to 8 people simultaneously), the RA360 (portable OSHA screening audiometer with ambient noise monitoring), and the AR993 (modular portable sound booth). Supporting these hardware products are the HearCon Software Package for workflow management and data integration, the Oscar 360 biological check accessory, and an optional octave band monitor. The products are designed to serve health and safety professionals conducting on-site workplace testing, clinics requiring efficient hearing conservation programs, and mobile testing companies needing portable, quick-deploy solutions across North America.

Direct peers

• MAICO Diagnostics: Manufacturer of audiometric and tympanometric instruments with a long-standing product line targeting hearing screening, occupational health, and ENT clinics. MAICO's screening audiometers compete head-to-head with Tremetrics in industrial and clinical hearing conservation programs.
• Interacoustics: Demant-owned manufacturer of audiology and vestibular diagnostic equipment with significant overlap in clinical and occupational audiometry. Operates as a sister brand to Tremetrics under the same parent but competes externally for the same customer base of audiologists and occupational health practitioners.
• Benson Medical Instruments: Specialized US manufacturer of occupational audiometers (B-Series) focused on industrial hearing testing. Operates in the same OSHA-driven niche as Tremetrics, with comparable products for workplace screening and mobile testing companies.
• Frye Electronics: US manufacturer specializing in occupational audiometers (FONIX series) used in industrial hearing conservation programs. Provides near-direct competition to Tremetrics in mobile hearing testing vans and OSHA-compliant audiometric screening for industrial customers.
• Intelligent Hearing Systems (IHS): Manufacturer of otoacoustic emission (OAE) and auditory brainstem response (ABR) equipment used in occupational and newborn hearing screening. Overlaps with Tremetrics in workplace hearing conservation diagnostics, particularly for hearing-loss monitoring programs.
• Otometrics (Demant): Demant-owned audiology diagnostics brand competing in clinical and occupational hearing assessment. As a sister brand to Tremetrics within the same corporate group, its product portfolio directly mirrors Tremetrics' clinical audiometer positioning.
• Amplivox: UK-based manufacturer of portable and clinical audiometers with a strong occupational health footprint. Competes against Tremetrics RA660/RA360 in workplace hearing screening and industrial compliance testing globally.
• Grason-Stadler (GSI, part of Inventis Group): Established manufacturer of clinical and occupational audiometric equipment. GSI's product portfolio (GSI AudioStar Pro, GSI TympStar) directly overlaps with Tremetrics' RA660/RA360 in clinical hearing testing, with comparable OSHA-focused occupational health use cases across audiologists and hearing conservationists.

Broad incumbents

• Natus Medical: Diversified neurodiagnostic and hearing diagnostics company with broad portfolio across audiometry, OAE, ABR, and balance testing. Acts as a larger incumbent that bundles multiple modalities into enterprise contracts competing against Tremetrics' more focused occupational audiometry offering.

Emerging players

• SHOEBOX Audiometry: Tablet-based audiometry platform focused on occupational hearing testing with FDA-cleared iPad-based screening technology. Represents an emerging low-cost alternative delivery model that could disrupt the traditional dedicated audiometer form factor of Tremetrics' products.
