Air Conduction Audiometry. Air conduction audiometers transmit sound vibrations to the eardrum for the purpose of identifying obstruction or hearing loss in the outer, middle and inner ear. This type of audiometry effectively measures hearing ability and hearing thresholds. Everyday natural sound waves are carried through the ear.

What is air conduction? -describes the hearing sensitivity of the entire auditory system (outer, middle and inner ears) -signals are presented through air via earphones. What are supra-aural (circumaural) earphones? earphones mounted in cushions that are placed over the pinna. -standard for many years.

Pure tone audiometry (PTA) air conduction thresholds at frequencies 250, 500, 1000, 2000, 4000 and 8000 Hz were obtained with an Automated Method for Testing Auditory Sensitivity (AMTAS) automated audiometer in a sound-treated booth ( Eikelboom et al., 2013 ). Average four frequency PTA (4FA) was obtained by using the average from the thresholds at 500, 1000, 2000 and 4000 …

Air Conduction Symbols. The air conduction threshold symbols should be drawn on the audiogram so that the midpoint of the symbol centers on the intersection of the vertical and horizontal axes at the appropriate frequency and hearing level (for example, see Figures 2, 3, 4, and 6). These symbols should be reserved for those conditions when stimuli are presented …

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 …
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
Air- and bone-conduction audiometry shall be accomplished with an audiometer and transducers that meet the applicable specifications of ANSI S3.6-2004 ( American National Standards Institute, 2004b) and are appropriate to the test technique being used. Exhaustive electroacoustic calibrations should be performed annually using instrumentation traceable to the National …
