So, there is obvious hearing loss that you can measure on audiograms, but now we have a new appreciation for the type of hearing loss that you are describing, and it's more common among young people, and if they go through standard audiometric testing, it'll be perfect. All of their audiometric thresholds are fine. However, they report that they cannot hear clearly in a noisy background, or they have this tinnitus that they didn't have before.
