App-Based Seal Test

What it is:

Some mobile device applications claim to test the seal of a hearing protector using the device's microphone and speaker.

Output: Pass/Fail only (no PAR is generated)

• Current versions may not store records

• Requires specialist equipment (specific app and potentially additional hardware)

• Reliability and accuracy can vary

Why it matters: App-based tests are an emerging technology. Employers should ensure any system used has been validated and can provide records for documentation purposes.
