audiogrammille

Audiogrammille is a neologism in audiology that refers to a compact, longitudinal representation of hearing thresholds, combining elements of a standard audiogram with a time dimension. The term appears in discussions of data visualization and long-term monitoring rather than as a recognized clinical test.

In typical implementations, an audiogrammille is plotted as a two-dimensional visualization in which frequency (for example across the conventional 125 Hz to 8 kHz range) is displayed along one axis and a longitudinal index (such as session number or elapsed time) along the other. Color intensity, shading, or line thickness encodes the decibel hearing level at each data point, producing a dense map of auditory sensitivity over time.

The purpose of the audiogrammille is to enable rapid assessment of how an individual's hearing changes across sessions or to compare patterns across a population. It can help identify stable thresholds, progressive loss, fluctuations, or responses to interventions in a single view, reducing the need to inspect multiple separate audiograms.

Data sources for an audiogrammille include clinical pure-tone audiograms, tele-audiology measurements, or self-administered screening results, all standardized to a common unit such as decibels hearing level (dB HL).

Status and outlook: the audiogrammille remains a conceptual or exploratory visualization rather than a widely adopted clinical metric. There is no formal standard for formatting, color schemes, or interpretation, and practitioners rely on context and accompanying data to avoid misinterpretation. Further methodological work would be required to establish best practices and interoperability.
