Sensory adaptation has occurred. More specifically, Smell Sensory Adaptation. Sensory adaptation occurs when you become used to the intensity and presence of a particular stimulus, that it Falls below the threshold for it to be felt anymore. Or Given in the article, Sensory Adaptation, Sensory adaptation is, the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. (Sincero, 203) You only feel changes when the intensity increases or decreases proportionately to the initial stimuli. For example, if 00 light bulbs are on, it takes about ten tonights out before you notice the difference. Sensory adaptation is important for life as we know it. You would constantly be irritated by the influx of new stimuli such as light, sound, and tactile pressure, if not for sensory adaptation, you would very well be dead by now. The Sensory has 2 types: Absolute threshold and Difference threshold.
The absolute threshold is the smallest level of energy required by an external stimulus to be detectable by the human senses, including vision, hearing, tas
te, smell, and touch. It is more precisely defined as the degree of intensity of a stimulus necessary to correctly detect that stimulus 50% of the time. Stimuli at or above the absolute threshold – those which can be detected – are called supraliminal. With sensory adaptation, we have 5 senses: Vision, Hearing, Taste, Smell, And Touch. Each one is used for a different purpose. Hearing Sensory Adaptation Our ears adapt to the loud sound when it hits the small bones in the inner ear. The loud sound leads to the contraction of the inner ear marrow. This downturn causes the transmission of sound vibrations in the inner ear to be reduced or delayed. And with this, the audio vibrations follow. This auditory adaptation process, however, usually does not work very well with sudden or immediate loud sounds. (Sincero,203) For example, with shooting a shotgun without ear protection, or hearing will suddenly go faint. With the loud ringing from the gun taking over. Or with tv shows. At first, we will notice the sounds there, but every so slowly, our minds begin to get used to the sounds.
