The concept can be applied to all senses as in:

Originally it was thought that there was some absolute levels which reflected human consciousness,, but later signal detection experiments revealed a gradual onset of detection reflecting probabilities of response to a stimulus at different intensities or levels of the target.

Gustav Fechner did much of the early work determining the absolute thresholds for the sensory modalities. He used three main methods:
