The graph, plotted by connecting all hearing threshold values for all tested frequencies, is called “audiogram,” “pure-tone audiogram,” or “tonal audiogram.” Hearing thresholds are measured in dB HL units, which are calibrated on normal-hearing young populations so that the bone conduction curve lies slightly above the air conduction curve.

More precisely, threshold is considered the intensity at which a patient can just detect the signal 50% of the time. The audiogram gives an easy-to-read profile of the person's threshold of hearing relative to normal hearing at each …

1. Pure tone: A single frequency sound. 2. Audiometer: Equipment used to generate pure tones of varying frequency and loudness and control their presentation. 3. Air conduction (AC) threshold: lowest level dB HL (hearing threshold) at which the subject perceives 50% of pure tones introduced via earphones or speakers.
Perspectives on the Pure-Tone Audiogram
https://pubmed.ncbi.nlm.nih.gov/28722648/
Results: The pure-tone audiogram provides information as to hearing sensitivity across a selected frequency range. Normal or near-normal pure-tone thresholds sometimes are observed despite cochlear damage. There are a surprising number of patients with acoustic neuromas who have essentially normal pure-tone thresholds. In cases of central deafness, depressed pure …
