Pure Tone Audiogram and Interpretation - Epomedicine
https://epomedicine.com/medical-students/pure-tone-audiogram-and-interpretation/
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.

This article addresses the basic interpretation of pure-tone audiometry as measured using a pure-tone audiometer and as summarized in a standard graphical format called an audiogram. An audiogram is a convenient tool that characterizes the degree, type, and configuration of a hearing loss. Audiogram
Perspectives on the Pure-Tone Audiogram - PubMed
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.
Pure tone audiograms from hearing-impaired children. II ...
https://pubmed.ncbi.nlm.nih.gov/7214068/
Pure tone audiograms and speech audiograms using sentence lists were obtained from 150 8-16-year-old children with pure tone hearing losses ranging from mild to severe. Most of the hearing impairments were cochlear in origin. Three 'speech-hearing' measures were selected from the speech audiograms, …

-70 -60 -50 -40 -30 -20 What to expect: This little demo is not too unlike the standard audiometric test known as a pure-tone audiogram. We present pure tones of different frequencies at different sound levels, and adjust their level until they become inaudible in order to measure the "threshold".
Pure Tone Audiometry Test - Procedure, Results ...
https://www.healthcheckup.com/tests/what-is-pure-tone-audiometry/
Pure Tone Thresholds (PTT) show the quietest sound audible at least 50 percent of the time. The sensitivity of hearing is shown on an audiogram, that is a graph showing intensity as a function of frequency. With that graph, the doctor can easily help the individual accordingly for it contains all the required information of an individual hearing.
Pure Tone Audiometry - an overview | ScienceDirect Topics

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.
