On a graph, intensity level is represented on which axis?

Intensity level in sound measurement is typically represented on the vertical axis of a graph. This convention allows for a clear representation of sound levels, often measured in decibels (dB). When plotting sound intensity against frequency or time, placing the intensity level on the vertical axis provides a visual representation that effectively illustrates how sound intensity changes in relation to the other variable being measured.

The use of the vertical axis for intensity level is rooted in standard practices in various fields, including audiology and acoustics, where it is critical to visually communicate the strength of sound in relation to the parameters of interest. This convention ensures clarity and consistency in the presentation of data, making it easier for practitioners and researchers to interpret sound levels accurately.
