Serial audiogram configurations primarily display numerical data to illustrate an individual's hearing threshold levels across various frequencies over time. This numerical representation allows for the assessment of changes in hearing ability, which is crucial for monitoring the effects of noise exposure or other auditory hazards in occupational settings.

The numerical values plotted on an audiogram reflect specific hearing thresholds measured in decibels (dB) across the frequency spectrum, usually ranging from low frequencies (around 250 Hz) to high frequencies (up to 8000 Hz). By comparing these threshold levels over multiple audiograms, practitioners can identify trends, detect deterioration or improvement in hearing, and make informed decisions regarding hearing conservation strategies.

Other options do not accurately reflect the data shown in serial audiograms. While graphical representations are part of the presentation, the key focus is on the numerical data that provides precise thresholds of hearing. Subjective interpretations and visual sound charts play different roles in audiological assessments and do not represent the structured and quantifiable nature of serial audiograms.
