Why am I being asked to do a hearing test?

Hearing loss and symptoms such as tinnitus (the perception of sound, like ringing, buzzing, or hissing, in your ears or head without an external source) are common and can affect communication, wellbeing, and even cognitive health. Research shows that reduced hearing may be linked to memory and thinking decline. Many people reported hearing problems in the REACT survey as a symptom of Long COVID. By taking part in this test, you help researchers understand these connections and support work to improve long‑term health.
