Industrial Noise Monitoring Checklist [FREE PDF]

Occupational noise-induced hearing loss (NIHL) is one of the most common and preventable work-related conditions, affecting approximately 17% of all noise-exposed workers in the United States according to NIOSH data. OSHA 29 CFR 1910.95 mandates hearing conservation programs when employee noise exposures equal or exceed an 8-hour time-weighted average (TWA) of 85 dBA, requiring monitoring, audiometric testing, hearing protection, and training. Industrial hygienists and EHS managers must conduct

  • Industry: Industrial Hygiene
  • Frequency: Quarterly
  • Estimated Time: 45-60 minutes
  • Role: Industrial Hygienist
  • Total Items: 42
  • Compliance: OSHA 29 CFR 1910.95 Occupational Noise Exposure, NIOSH REL for Occupational Noise Exposure (85 dBA as 8-hr TWA, 3 dB exchange rate), ACGIH TLV for Noise 2023 Edition (85 dBA TWA, 3 dB exchange rate), OSHA 29 CFR 1910.1020 Access to Employee Exposure and Medical Records, OSHA 29 CFR 1910.134 Respiratory Protection (where noise co-exposure with chemicals occurs)

Pre-Monitoring Preparation and Equipment Calibration

Verify that all noise monitoring instruments are properly calibrated and that monitoring conditions are representative of typical work operations.

  • Has the sound level meter or dosimeter been calibrated with a certified acoustical calibrator before monitoring?
  • Is the calibration record for monitoring equipment current and within the manufacturer's recommended interval?
  • Is the monitoring instrument set to A-weighting (dBA) and slow response for TWA measurements?
  • Are production operations representative of typical daily noise-generating activities during this monitoring period?
  • Have employees whose exposures may equal or exceed 85 dBA TWA been identified for personal dosimetry?

Area Noise Level Measurements

Document area sound pressure levels throughout the work zone using a sound level meter to map noise hazard areas.

  • Have area noise measurements been taken at representative employee work positions throughout the monitoring zone?
  • What is the highest area noise level measured in this work zone (dBA)?
  • Are there any impulsive or impact noise sources (e.g., stamping, hammering, explosions) present in the work area?
  • Have noise contour maps or zone identifications been created to demarcate areas exceeding 85 dBA?
  • Are noise hazard warning signs posted at the boundary of areas exceeding 85 dBA TWA?

Personal Noise Dosimetry Results

Review and document personal noise dosimeter results for employees in noise-exposed job classifications.

  • Were personal noise dosimeters worn for the full duration of the representative work shift (minimum 2 hours)?
  • Do any measured employee 8-hr TWA exposures equal or exceed the OSHA action level of 85 dBA?
  • Do any measured employee 8-hr TWA exposures equal or exceed the OSHA permissible exposure limit (PEL) of 90 dBA?
  • Have dosimetry results been recorded and are they available for employee notification within 5 working days?
  • Are dosimetry records stored in a manner accessible to employees upon request as required?
  • Have exposure results been compared to NIOSH REL of 85 dBA (3 dB exchange rate) for additional risk evaluation?

Engineering and Administrative Controls

Assess the adequacy and implementation of engineering and administrative noise controls in the work area.

  • Have feasible engineering controls been implemented for noise sources exceeding the OSHA PEL of 90 dBA?
  • Are equipment enclosures, vibration dampening, mufflers, or acoustic barriers present and maintained on high-noise equipment?
  • Are administrative controls (e.g., job rotation, limited time in high-noise areas) utilized to reduce employee noise dose?
  • Is a preventive maintenance schedule in place for all noise-generating equipment to prevent increased noise from wear?
  • Is the effectiveness of existing engineering controls documented and reviewed at least annually?

Hearing Protection Device (HPD) Program

Evaluate the selection, availability, fit-testing, and use of hearing protection devices for noise-exposed employees.

  • Are hearing protection devices provided at no cost to all employees exposed at or above the 85 dBA action level?
  • Is a variety of HPD types (earplugs, earmuffs, semi-inserts) available for employee selection?
  • Have all noise-exposed employees been trained on the proper insertion, use, and care of their selected HPD?
  • Has the noise reduction rating (NRR) of selected HPDs been verified to provide adequate attenuation for measured exposure levels?
  • Are employees consistently observed wearing HPDs in posted hearing protection required areas?

Audiometric Testing Program

Review the status and compliance of the audiometric testing program for noise-exposed employees.

  • Have all employees enrolled in the hearing conservation program received a baseline audiogram within 6 months of first exposure?
  • Are annual audiograms being conducted for all hearing conservation program participants?
  • Have any standard threshold shifts (STS) of 10 dB or more in either ear been detected in the past 12 months?
  • Are audiometric test booths or test environments meeting OSHA-required maximum allowable ambient noise levels?
  • Are audiometric records retained for the duration of each affected employee's employment?
  • Is the audiometric technician or audiologist conducting tests currently certified or licensed as required?

Training and Recordkeeping Compliance

Verify that all required hearing conservation training elements are delivered annually and that program records are complete and accessible.

  • Have all noise-exposed employees received annual hearing conservation training within the past 12 months?
  • Does training content include the effects of noise on hearing, HPD attenuation, and audiometric testing purpose?
  • Are training records documenting employee attendance and content retained and available for OSHA inspection?
  • Are noise exposure monitoring records retained for at least 2 years as required?
  • Is the written hearing conservation program document current, reviewed annually, and accessible to employees and OSHA?

Deficiencies and Corrective Action Plan

Document any program deficiencies identified during this assessment and establish a corrective action plan with assigned responsibilities.

  • Were any noise monitoring, HPD, audiometric, or training program deficiencies identified during this assessment?
  • Please describe all identified deficiencies and the specific regulatory requirements not being met?
  • Have corrective actions been assigned to responsible personnel with documented target completion dates?
  • Please attach photographs of noise sources, control measures, HPD stations, or other relevant conditions?
  • Has this completed assessment been reviewed and approved by the responsible EHS Manager or Safety Director?
