Introduction
In general, an audiogram report requires reviewing the average air-conduction and bone-conduction hearing thresholds. Air-conduction threshold measures the ability of sound to travel through the outer ear, middle ear, and inner ear. By measuring air-conduction thresholds, doctors can assess a person's auditory sensitivity to different sound frequencies under normal hearing pathways. Bone-conduction threshold measures the ability of sound to be transmitted through the bones.
Under normal circumstances, an audiology report should be evaluated based on the average air-conduction and bone-conduction hearing thresholds. The specific analysis is as follows:
Air-conduction threshold testing measures the ability of sound to travel through the outer ear, middle ear, and inner ear. By measuring air-conduction thresholds, doctors can assess a person's auditory sensitivity to different sound frequencies under normal hearing pathways. Bone-conduction threshold testing evaluates the ability of sound to be transmitted through the bones. This test determines whether the inner ear can properly receive sound signals, independent of any influence from the outer ear or middle ear. Generally, if both the average air-conduction and bone-conduction thresholds are below 25 decibels (dB), hearing is considered within the normal range. If the average thresholds exceed 25 dB, it may indicate hearing loss.
If hearing loss is detected, it is recommended to promptly visit a reputable hospital to determine the underlying cause and receive appropriate treatment.
