Building a complete picture of sound and vibration exposure

Understanding how noise and vibration vary across the work environment is essential to protecting worker health, supporting clear communication and maintaining the safe performance of critical tasks. A complete picture considers exposure duration, changing operating conditions, equipment cycles, impulsive events and the ways tools or vehicles transmit vibration.

Onterris helps organizations characterize exposures, identify significant sources and develop practical controls that fit the work. Our industrial hygiene services combine field monitoring, engineering insight and hearing conservation program support to help clients protect workers, strengthen compliance and make well-informed investment decisions.

Supporting Your Industry

Organizations in complex and highly regulated industries rely on noise and vibration assessments to understand worker exposure, evaluate controls and strengthen hearing conservation and worker protection programs.
why it matters

Proactive exposure management helps prevent lasting hearing impacts

Understanding noise and vibration exposure over time helps organizations act earlier and focus resources where they can have the greatest impact. Credible exposure data can reveal changing conditions, identify priority sources and tasks and inform practical strategies to protect worker health and performance.
  • Changes in production can create new or different exposure conditions
  • Managing high noise supports effective communication, alarm recognition and situational awareness
  • Monitoring strategies can account for short, intense events as well as routine exposure
  • Hand-arm and whole-body vibration require consideration of distinct health and performance factors
  • Combining hearing protection with controls at the source can provide a more comprehensive approach to exposure management

Connect exposure insights with effective controls and program action

Onterris designs evaluations around representative workers, tasks, equipment and operating conditions. The resulting exposure data helps organizations prioritize effective controls and make well-informed program decisions.
