Such exams have limitations, but they could serve as useful screening tools. If you want to try one, there are things to consider.
Some use testing methods backed by solid science, says Nicholas Reed, an audiologist and assistant professor in epidemiology at the Johns Hopkins Bloomberg School of Public Health in Baltimore, while others have little evidence to support them.
A key limitation of apps and online tests is that they can’t rule out potentially reversible causes of hearing loss, such as, the way an audiologist would during an in-person test. “If you do a self-hearing screen, a person can’t look into their own ear,” says Yula Serpanos, a professor in communication sciences and disorders at Adelphi University in Garden City, N.Y.That said, an online test could serve as a useful screening tool. If you want to try one, consider the following.
The two main types both have advantages and drawbacks. In pure-tone audiometry, which involves some aspects of the testing that audiologists perform, tones are played in decreasing volumes to determine your specific level of hearing loss. But these hearing tests require the proper equipment to be used — a test given on an iPad, for example, may work with only AirPods headphones — which limits options.
In the second type, known as speech-in-noise or digits-in-noise , you’ll be asked to identify words, numbers or phrases amid background noise. DIN tests generally don’t require specific hardware. But they’re less precise, and they serve as a more general indicator of a problem.Validation: The word “validation” in the description suggests that a test has been scientifically evaluated for accuracy, Serpanos says. It’s even better if the description has a summary of the validation studies. One such test is theTreat tests that provide scanty directions or explanation of their methods with caution, Reed says. A test should also monitor background noise and alert you if it’s too loud for an accurate result.
