How does the hearing test work?

Our hearing test is a validated, audiological screening test that uses numbers presented with background noise (commonly referred to as a speech-in-noise (SIN) screening).

The test determines your speech recognition threshold (in a dB signal-to-noise ratio). This reflects your ability to understand speech in the presence of background noise, something individuals with hearing difficulty typically struggle with. If your results are reduced, you are likely to benefit from a hearing aid.

How accurate is an online hearing test?

Great question, because online hearing ‘tests’ are generally not clinically validated. However, the Lexie online test technology has been widely validated, with results published in multiple scientific peer-reviewed journals. The accuracy of our hearing test exceeds 90% and the test can reliably be taken on your PC, tablet or smartphone with any set of head/earphones.

Compared with traditional pure-tone audiometry, speech-in-noise tests do not require calibrated equipment and are less sensitive to environmental noise. Another advantage of SIN tests is that they measure functional real-life difficulties with speech comprehension in background noise. The screening test picks up all kinds of hearing losses and can be completed within 2 minutes. The results are highly correlated with pure-tone audiometry thresholds. (Potgieter et al., 2016; Potgieter et al., 2017).
