What the Course Entails and Exam Details

The Tri-Service course follows a structured curriculum that blends theoretical knowledge with intensive hands-on training. It covers the core pillars of an effective Hearing Conservation Program as defined by DoD and CAOHC standards. Candidates are extensively trained in the anatomy and physiology of the ear, the physics of sound, hazardous noise identification, and appropriate hearing protection devices. Crucially, the course provides deep-dive training on the specific equipment and software used within the military. Candidates learn the precise calibration and operation of microprocessor audiometers and the management of the Defense Occupational and Environmental Health Readiness System - Hearing Conservation (DOEHRS-HC) database, which is the system of record for all DoD hearing data. A primary focus is placed on establishing valid baseline and annual hearing thresholds, identifying significant threshold shifts, and counseling service members on proper prevention techniques.

What to Expect in the Final Exam

The certification process concludes with a standardized final assessment, comprising two distinct components: a practical practicum and a comprehensive written exam. The hands-on practicum must be completed successfully before a candidate is eligible to challenge the written test. This practicum requires candidates to demonstrate proficiency in operating audiometric equipment, conducting a valid hearing screening, and properly fitting various types of military hearing protection devices under the direct observation of a certified instructor or audiologist. Following the successful practical evaluation, candidates take the standardized written exam. This exam is usually proctored on-site. The written portion focuses on the application of regulatory protocols, equipment troubleshooting, data management in DOEHRS-HC, and auditing principles. A minimum score of 70% is generally required on the written standardized exam to obtain certification.

How to Study and Exam Centers

Effective preparation for the Tri-Service certification requires focusing on both knowledge and skill acquisition. Candidates must thoroughly review the provided course manuals, DoD regulations, and Service-specific hearing conservation directives. Focusing heavily on the Phase 2 practical skills is vital; mastery of the practical component is a prerequisites for testing. You should practice troubleshooting the audiometric equipment you will be using and familiarize yourself with the user interface and common entry protocols for the DOEHRS-HC system. Regarding testing centers, this exam is not administered through standard civilian providers like Pearson VUE. Instead, the testing is integrated directly into the training course structure at authorized DoD installations. These certified training centers are located at key military treatment facilities and schools, such as the United States Air Force School of Aerospace Medicine (USAFSAM) and specified Army Public Health centers. Students must enroll in the certified course through their Service Hearing Program Manager to access both the training and the certification exam.
