Pure-tone audiometry is a “gold” standard test of audiologic examination. Its role is to assess whether hearing acuity is normal or impaired. Air conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.125 kHz to 8 kHz with the use of headphones.

Objective: COVID-19 has been prohibitive to traditional audiological services. No- or low-touch audiological assessment outside a sound-booth precludes test batteries including bone conduction audiometry. This study investigated whether conductive hearing loss (CHL) can be differentiated from sensorineural hearing loss (SNHL) using pure-tone air conduction …

Pure tone audiometric air conduction testingis performed by presenting a pure tone to the ear through an earphone and measuring the lowest intensity in decibels (dB) at which this tone is perceived 50% of the time. This measurement is called threshold.

In air-conduction testing, a pure tone is presented via an earphone (or a loudspeaker). The signal travels through the air in the outer ear to the middle ear and then to the cochlea in the inner ear. In bone-conduction testing, instead of using an earphone, an electromechanical earphone is …

How is pure tone audiometry done? Pure-tone audiometry is the most commonly used test to measure auditory sensitivity. Pure-tone signals are delivered to the ear via air conduction and bone conduction at a variety of frequencies, and the patient responds to the sound by signaling the examiner with a button or by raising a hand.
Air Conduction vs. Bone Conduction: Candidacy Guide for ...
https://blog.medel.pro/bone-conduction-candidacy-audiogram/
Air conduction thresholds are usually marked with an O for the right side and an X for the left side. Bone Conduction Thresholds. Bone conduction audiometry sends vibrations via a bone oscillator directly to the inner ear, so bone conduction thresholds should be equal to or better than air conduction thresholds in the same ear.
