Sound level calibration is a prerequisite to properly measuring hearing loss. Our hearing test is the only online hearing test we know of that offers you a way to calibrate your headphones or speakers, giving you the opportunity to reliably estimate your hearing loss. Use our test with confidence to confirm normal hearing, or a mild, moderate, or severe hearing loss. This test-like any other hearing test-requires a decent pair of headphones (good speakers will work too, although headphones are preferred), and a quiet environment.
