A referral to visit an audiologist is made for patients with an At risk hearing result. Additionally, if the patient indicates that he/she suspects that they might have a hearing problem, the patient needs to be referred to an audiologist and this will be indicated on the VHC report.


The hearing test will determine the patient’s speech reception threshold (SRT). The hearing risk is calculated based on the SRT values. There are four risk categories:

1. No risk (hearing is good);

2. Low risk (hearing is OK),

3. Moderate risk (hearing is OK), and

4. At risk (hearing problem).
