Test prep activities I - Room scan & headphones check

The test prep screen will allow you to perform routine hardware checks to ensure your device is functioning properly, and in some cases, to maintain compliance with your regulatory requirements.

Important notes before you begin

• Before you begin your testing for the day, make sure you are logged in under your own user account.
• Ensure you select a room that can serve as a suitable testing environment. The room should be free of any background noise or potential disturbances, and should contain a table and chairs for the subject and examiner to use. Watch the following brief video for tips on how to select and prepare a room for hearing testing.

• The iPad should be placed in the provided iPad stand (alternatively, if your case has a stand, you can use that) on a secure table. It should not be held in one's hands or placed flat on the table as this can cause vibrations that will trigger the noise monitoring. Ensure the table and iPad are not located near any vents, fans, or appliances that emit noise (refrigerators, etc.).

• If you receive the message in the image below telling you to add new headphones that means your old headphone data has been removed after the headphones were sent for recalibration. You need to install new headphones to the app to start the Test Prep Activities. Contact an admin user if you do not have the new headphones.

Performing a test prep activity

In the PureTest app, tap on Test Prep in the bottom left corner to access the Test Prep screen.

If you have configured your test prep steps to be required, you will be blocked from testing until they have been passed successfully. If you have them set to Never, you can still perform the test prep activities, but will not be blocked from testing if you do not perform them.

For occupational hearing testing, we recommend to follow the default setting of Daily. This will require you to perform a test prep every 24 hours.

Note: If your test prep settings are configured to be required at a regular interval, you must complete the test prep activities in order from Step 1 to Step 3. If you have them set to Never, then the order does not matter.

Note on biological verification: Some organizations are not required to perform biological verification as part of their test prep, and the biological verification step may be removed by a system administrator. If you are not required to perform biological verification, your test prep screen will look like the image below and you will only be required to perform steps 1-2.

Step 1: Room scan

Before proceeding, make sure the iPad is placed in the iPad stand provided, with the microphone unobstructed. This will ensure that the noise monitoring functions correctly. The iPad should not be placed flat on the table or held in one's hands as this can cause vibrations that will trigger the noise monitoring.

1. Tap the Room Scan button. The button will also show you the date of your last room scan on the right.

2. If you have an external microphone, you will then be prompted to plug it in. Once it is plugged in, tap Next.

3. The PureTest app will then perform the ambient noise room scan. Once the scan is complete, the app will let you know if the scanned area is a suitable testing environment based on the level of ambient noise detected. If the room scan detects any ambient noise above the maximum levels, the app will indicate which frequencies failed the room scan, and will ask for a re-scan.

   • Note: The test will also indicate if one of your frequencies passed, but was close to failing.

   • Important: Subject hearing tests must be performed in the same room where you performed this room scan. Proceeding with testing in an unsuitable environment will produce invalid results.

     

4. After confirming the results, tap on Done (see above image). You will then be prompted to remove your external microphone (see below image).

5. Once you have passed a room scan, the Headphones Check button will be unlocked.

Step 2: Headphones check

1. Tap on the Headphones Check button to begin your headphones check. You will be prompted to plug in your headphones.

   

   • Warning: Admin users can block testing with expired headphones across the entire organization. This is done to maintain regulatory compliance and prevent the misdiagnosis of test subjects. If your organization is blocked from using expired headphones, you will not be able to perform the Headphones Check, nor will you be able to perform any subject hearing tests. Install new headphones to complete the verification. Contact the admin user if you do not have the new headphones.

2. The headphone check will begin with the left speaker. Tap on the Play button and the app will present a tone.

   • If the tone is loud and clear, tap on the Pass button.

   • If the tone contains any crackling, static, or intermittent sounds, tap on the Fail button.

3. Once you have confirmed the left speaker, repeat the process for the right speaker.

   

4. Once you have confirmed that both the left and right speakers are functioning correctly, tap the Done button on the results panel. This will complete your daily headphone check.

   

   • Note: If during your testing session, you notice that the headphones have received, or may have received, some form of damage, you can always return to the test prep screen and redo the headphones check. This is good practice to ensure that your headphones are always functioning correctly.

5. Once you have passed a room scan, the Biological Verification button will be unlocked (if biological verification is enabled.) and you can proceed to Step 3. If biological verification is disabled, it will not be present on the test prep screen, and your test prep session will now be complete.

Step 3: Biological verification
