OSHA 1910.95(e): Employee Notification of Noise Monitoring Results

Share article

Noise Monitoring·OSHA Compliance·10 min read·Updated March 2026

OSHA 1910.95 contains two distinct employee notification requirements that are frequently confused or conflated: the noise monitoring notification under 1910.95(e), and the standard threshold shift notification under 1910.95(g)(8). They address different information, carry different obligations, and involve different timelines. The 1910.95(e) notification requirement applies when noise monitoring is conducted — it obligates the employer to notify affected employees of the monitoring results and to provide access to monitoring records. This guide explains exactly what 1910.95(e) requires, who qualifies as an affected employee, what method of notification satisfies the standard, and what records the employer must maintain and make available.

Soundtrace documents noise monitoring results in the cloud portal, enabling employers to demonstrate that affected employees have access to their monitoring data as required by 1910.95(e) and 1910.95(m).

1910.95(e)
The OSHA provision requiring employee notification of noise monitoring results — separate from the STS notification at 1910.95(g)(8)
2 years
Required retention period for noise monitoring records under 1910.95(m)(3) — shorter than audiometric record retention
Post or notify
Notification may be individual written notice or posting in a location accessible to all affected employees
The Regulatory Text

1910.95(e): “The employer shall notify each employee exposed at or above the action level of the results of occupational noise exposure measurements. Employees shall have access to noise exposure measurement records.”

Two distinct obligations: notification of results AND access to records. Both apply when monitoring is conducted.

What Triggers the 1910.95(e) Requirement

The notification obligation under 1910.95(e) is triggered whenever the employer conducts noise monitoring under 1910.95(d). Monitoring is required when there is reason to believe that any employee’s exposure may equal or exceed the action level of 85 dBA TWA. Once monitoring is conducted, the employer must notify affected employees of the results and must make the records accessible to them.

This obligation applies to each monitoring event — not just the initial survey. If noise conditions change materially (new equipment, process changes, facility layout modifications), additional monitoring may be required, and each monitoring event triggers the notification obligation anew.

1910.95(e) Noise Monitoring Notification: Two-Part Obligation
Both parts are required when monitoring is conducted. The notification obligation covers all employees measured at or above 85 dBA TWA.
Noise monitoring conducted Any employee at or above 85 dBA TWA Part 1: Notify employees of results Individual notice OR posting in accessible location All affected employees must receive or have access Part 2: Provide access to records Employees and designated representatives Records retained 2 years (1910.95(m)(3))

Who Qualifies as an Affected Employee

An affected employee under 1910.95(e) is any employee whose noise exposure measurement at or above the action level triggered the monitoring requirement or who was measured at or above 85 dBA TWA during monitoring. This category is broader than the HCP enrollment list — it includes any employee exposed at or above the action level, regardless of whether they currently wear hearing protection or whether they have already been enrolled in the HCP.

Practically, the notification obligation covers:

  • All employees enrolled in the HCP (who are enrolled specifically because they are at or above the action level)
  • Employees who were measured at or above the action level during a noise survey, even if they haven’t yet been formally enrolled
  • Supervisors and engineers who regularly work in areas measured at or above the action level
When in doubt, notify

If a monitoring survey measured noise levels at or above 85 dBA TWA in a work area, all employees who regularly work in that area are affected employees for purposes of the notification requirement, even if individual dosimetry was not conducted for each one. The safer compliance approach is to notify all workers in affected areas rather than relying on the assumption that individual measurement results are precisely determinative of who qualifies.

Acceptable Notification Methods

OSHA does not prescribe a specific format for the 1910.95(e) notification. The standard permits notification by two methods:

  • Individual written notification: A written document provided directly to each affected employee stating their measured noise exposure level and the date of measurement. This is the more documentable approach and provides clear evidence of compliance.
  • Posting in a conspicuous location: Posting monitoring results in a location accessible to all affected employees — typically the work area where monitoring was conducted, a safety bulletin board, or a breakroom accessible to the affected workers. The posting must be accessible to all affected employees, not just those who happen to see it.
Posting alone may be insufficient in multi-shift operations

If affected employees work multiple shifts and the monitoring results are only posted during one shift, employees on other shifts may not have access to the information. Individual notification, or posting that is visible and accessible during all shifts in which affected employees work, is the defensible approach.

Employee Access to Monitoring Records

In addition to notifying employees of monitoring results, 1910.95(e) requires that employees have access to noise exposure measurement records. Under 29 CFR 1910.1020 (the general access to employee exposure and medical records standard), employees and their designated representatives have a right to access exposure records within 15 working days of a request. Noise monitoring records fall within this access right.

Access to records means that employees can request to view or receive copies of their monitoring records. The employer must respond within 15 working days of a written request and cannot charge unreasonable fees for providing copies.

Record Retention Requirements

OSHA 1910.95(m)(3) requires employers to retain noise exposure measurement records for at least 2 years. This is significantly shorter than the retention requirement for audiometric test records (employment duration plus 30 years), but still requires a systematic record management approach:

Record TypeRetention PeriodCitation
Noise exposure measurements (dosimetry, area surveys)2 years1910.95(m)(3)
Audiometric test recordsDuration of employment + 30 years1910.95(m)(2)(ii)
Employee medical records (including audiograms)30 years post-employment1910.1020(d)(1)(i)
OSHA 300 Log (hearing loss entries)5 years1904.33

1910.95(e) vs. 1910.95(g)(8): Two Separate Requirements

These two notification requirements are frequently conflated but address entirely different obligations:

  • 1910.95(e) applies when monitoring is conducted. It tells employees what their noise exposure level is. It involves posting or individual notice of monitoring results, and it applies even to employees who have not yet been enrolled in the HCP.
  • 1910.95(g)(8) applies when an STS is confirmed by annual audiogram. It tells enrolled HCP participants that their hearing has changed. It requires written notification within 21 days of the STS determination. It applies only to enrolled HCP participants, not to all monitored employees.

▶ Bottom line: 1910.95(e) is about noise level results; 1910.95(g)(8) is about hearing change. Both require written communication to affected employees, but they are triggered by different events, apply to different populations, and serve entirely different protective purposes.


Frequently asked questions

What does OSHA 1910.95(e) require for employee notification of noise monitoring?
1910.95(e) requires employers to notify employees exposed at or above the 85 dBA action level of their noise monitoring results, and to provide access to monitoring records. Notification may be individual or by posting in an accessible location. Both the notification and the record access obligations apply whenever monitoring is conducted.
Who must be notified under 1910.95(e)?
All employees whose noise exposure at or above the action level triggered the monitoring requirement. This includes all HCP-enrolled employees plus any employee measured at or above 85 dBA TWA during the survey, even if not yet formally enrolled.
How long must noise monitoring records be retained?
OSHA 1910.95(m)(3) requires retention of noise exposure measurement records for at least 2 years. This is distinct from audiometric test records, which must be retained for the duration of employment plus 30 years.
What is the difference between the 1910.95(e) notification and the STS notification?
The 1910.95(e) notification informs employees of their measured noise exposure level and is triggered when monitoring is conducted. The 1910.95(g)(8) STS notification informs HCP participants that their audiogram shows a threshold shift and is triggered when an STS is confirmed. These are separate requirements for separate circumstances.
