What color represents the left ear in audiogram notation?

The color blue is universally used in audiogram notation to represent the left ear. This standard helps audiologists and hearing care professionals to easily identify and differentiate between the left and right ears when interpreting an audiogram. The right ear is represented by the color red. This color-coding system provides a clear visual reference, making it straightforward for practitioners to communicate findings accurately and effectively. This standardization is crucial for ensuring that hearing abilities are monitored and addressed correctly. Understanding this notation is key for anyone working with audiograms, as it aids in the accurate recording and assessment of a patient's hearing capabilities.
