The testing procedure is repeated at specific frequencies from 250 to 8000 hertz (Hz, or cycles per second) for each ear, and the thresholds are recorded on a graph called an audiogram. Bone conduction testing is done by placing an oscillator on the mastoid process and measuring threshold at the same frequencies. Masking noise is sometimes used in the nontest ear to …

Bone conduction audiometry is used for diagnostic purposes and is instrumental in identifying sensorineural hearing loss. Proper differentiation between conductive and sensorineural hearing loss is to compare hearing threshold levels from both air conduction and bone conduction audiograms. Audiologist, ENTs and other hearing specialists rely on air and bone conduction …

Bone conduction audiometry is a standard test performed in an audiologic evaluation. Bone scores help indicate the site of lesion and type of hearing loss that may be present; however, there are times when unexplainable air/bone gaps or bone thresholds poorer than air thresholds are obtained.
Bone Conduction Testing - Audien Hearing

What is Bone Conduction Testing? Bone Conduction Testing is actually very similar to pure tone testing in the way that ‘pure’ tones are played for you to respond to after hearing each tone. The difference lies behind how the tones are delivered. In bone conduction testing, the tones are not sent directly to the ear through headphones, rather they will go to behind your ear or forehead …

bone conduction thresholds, and/or speech discrimination testing. Sometimes these evaluations were done on all NHANES examinees, and some surveys included hearing evaluations on only a subset of examinees (such as children or adults). Table 1-1 summarizes the audiometric procedures included in each of the health examination surveys since 1960:

What is the advantage of completing bone conduction audiometry at the forehead vs the mastoid bone? Mastoid vs. Over 90% of BC testing is performed with mastoid placement although several studies have shown that forehead placement yields better test/retest reliability with less contributions from the middle ear to BC thresholds.

In bone-conduction testing, instead of using an earphone, an electromechanical earphone is placed on the skull. This allows for stimulation of the cochlea via mechanical vibration of the skull with almost no stimulation of the outer and middle ear.
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
Diagnostic standard pure-tone threshold audiometry, used most often in clinical settings, includes manual air-conduction measurements at 250, 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz (125 Hz under some circumstances) plus bone-conduction measurements at octave intervals from 250 Hz to 4000 Hz and at 3000 Hz as needed.

Limitations in High Frequency Bone Conduction Testing Question The ENT in our office would like to know the reason why 6000Hz is never tested for bone conduction. Answer There are transducer limitations above 4000 Hz that reduce the validity of bone conduction testing at higher frequencies. Please refer to the below references and recommendations.
