Industrial Noise Monitoring Checklist [FREE PDF]

Occupational noise-induced hearing loss (NIHL) is one of the most prevalent irreversible occupational diseases, affecting an estimated 22 million U.S. workers annually according to NIOSH. OSHA 29 CFR 1910.95 mandates that employers implement a Hearing Conservation Program (HCP) when employee noise exposures equal or exceed an 8-hour time-weighted average (TWA) of 85 dBA, the Action Level. NIOSH RELs are more protective, setting the recommended exposure limit at 85 dBA as a ceiling and recommendi

Pre-Monitoring Preparation & Instrument Calibration

Verify monitoring equipment is calibrated and operational before beginning noise measurements.

  • Has the sound level meter (SLM) or noise dosimeter been calibrated using a NIST-traceable acoustic calibrator before monitoring begins?
  • Is the monitoring instrument set to the A-weighting network and slow response for TWA measurements consistent with OSHA requirements?
  • Has the instrument's calibration certificate been verified as current and within the manufacturer's recommended calibration interval?
  • Has a post-calibration check been planned to confirm instrument accuracy drift within ±1 dB after monitoring?
  • Is background information about current production processes, equipment operation, and staffing levels documented to ensure monitoring is representative?

Area Noise Survey

Conduct area noise measurements to identify high-noise zones and map the facility's noise exposure profile.

  • Have area noise measurements been taken at all workstations and identified high-noise sources using an SLM set to A-weighted slow response?
  • Have measured area noise levels been recorded in dBA for each workstation or zone surveyed?
  • Are any measured area noise levels at or above 85 dBA TWA (OSHA Action Level)?
  • Are any measured area noise levels at or above 90 dBA TWA (OSHA Permissible Exposure Limit)?
  • Have noise contour maps or noise zone designations been updated based on current monitoring results?

Personal Noise Dosimetry

Document personal dosimeter placement, monitoring duration, and TWA results for individual employees.

  • Are personal noise dosimeters being used for employees with variable exposures or mobile job tasks where area monitoring is insufficient?
  • Is the dosimeter microphone positioned at the employee's shoulder near the ear canal in accordance with ANSI S12.19 placement requirements?
  • Has the dosimeter monitoring period covered a full representative work shift or been adjusted proportionally for partial-shift monitoring?
  • Have all personal dosimetry TWA results been recorded and compared against both the OSHA 85 dBA Action Level and 90 dBA PEL?
  • Have employees been notified of their personal noise dosimetry results within the timeframe required by OSHA?

Engineering & Administrative Controls

Evaluate the adequacy of noise control measures in place to reduce employee exposure.

  • Have all feasible engineering controls (e.g., equipment enclosures, vibration isolation, acoustic barriers, mufflers) been implemented for noise sources exceeding the 90 dBA PEL?
  • Are administrative controls (e.g., job rotation, limiting time in high-noise areas) documented and effectively reducing individual employee TWA exposures?
  • Are noise control equipment maintenance programs in place to ensure engineering controls remain effective?
  • Have noise levels in areas with implemented engineering controls been re-measured to verify actual noise reduction achieved?
  • Are employees purchasing new or replacement equipment informed of noise emission specifications to support low-noise equipment procurement (buy-quiet program)?

Hearing Protection Devices (HPD) Program

Assess the selection, fitting, use, and maintenance of hearing protection devices.

  • Are hearing protection devices (earplugs, earmuffs) provided at no cost to all employees exposed at or above the 85 dBA Action Level?
  • Is a variety of HPD types available to allow employee selection based on comfort, dexterity, and noise reduction requirements?
  • Have employees been individually trained on the correct insertion, fitting, and care of their selected HPD?
  • Is the selected HPD providing adequate attenuation to reduce employee exposure below the OSHA 90 dBA PEL (or below 85 dBA for employees with standard threshold shifts)?
  • Are employees observed consistently wearing HPDs in all posted hearing protection required areas?

Audiometric Testing & Medical Surveillance

Review audiometric testing program compliance and follow-up procedures for standard threshold shifts.

  • Have baseline audiograms been obtained for all employees enrolled in the Hearing Conservation Program within 6 months of first exposure at or above 85 dBA?
  • Are annual audiograms being conducted for all HCP-enrolled employees and compared against their established baseline?
  • Have standard threshold shifts (STS) of 10 dB or more at 2000, 3000, or 4000 Hz been identified and documented for any employees?
  • Are audiometric testing records retained for the duration of employment plus 30 years per OSHA medical records requirements?
  • Are employees with identified STS referred to a physician or audiologist for further evaluation and follow-up?

HCP Training & Recordkeeping

Confirm annual hearing conservation training completion and verify required program records are maintained.

  • Have all HCP-enrolled employees received annual training covering noise hazards, effects of noise on hearing, HPD use, and the purpose of audiometric testing?
  • Are noise monitoring records (area surveys and personal dosimetry results) retained for a minimum of 2 years per OSHA requirements?
  • Is the written Hearing Conservation Program document current, reviewed at least annually, and reflective of actual workplace conditions?
  • Have all noise monitoring exposure records been made available to employees upon request per OSHA 1910.1020 requirements?
  • Additional monitoring findings, corrective actions required, or program improvement recommendations?
