Comparison Tool
Pick any two hearing signatures and view them together — overlaid on one set of axes, or side by side. Each signature carries a description and its characteristic findings.
Comparing patterns directly is one of the fastest ways to build recognition: a sloping loss next to a flat one, or an asymmetric loss next to a symmetric profound loss, makes the distinguishing feature obvious.

Present responses to low intensities across all carriers, both ears.
Representative PTA ≈ 13 dB HL — Normal range.

Sloping high-frequency loss
Near-normal low frequencies, worsening toward the high frequencies.
Representative PTA ≈ 44 dB HL — Moderate range.
