Mild Sensorineural
Mild loss across the full range of pitches. Quiet speech is often missed, and following a conversation in a noisy room takes real effort. It can be there from birth or show up at any age, and it’s often the point where hearing aids first come up.

Pure-tone average is the quietest tone each ear can just hear, averaged across three pitches central to speech (500 Hz, 1 kHz, and 2 kHz). It’s the single number U.S. audiologists use to sum up an audiogram. 15 dB or lower is typical hearing, and every 10 dB higher means sounds need to be about twice as loud to be heard. Internationally, the World Health Organization averages four pitches, adding 4 kHz, so where high pitches have more loss its number comes out higher.
