The phrase "a decrease in sensitivity" is correct and usable in written English.
It can be used in contexts discussing changes in responsiveness, awareness, or perception, often in scientific, medical, or psychological discussions.
Example: "The study revealed a decrease in sensitivity to pain after the treatment was administered."
Alternatives: "a reduction in sensitivity" or "a decline in sensitivity."
There also may be present the phenomenon of masking; this is a decrease in sensitivity to one odour after exposure to another (for example, a strong-smelling disinfectant).
For instance, chemosensory loss, which is the loss of the ability to detect the odour of chemicals, can lead to a decrease in sensitivity in other senses.
Similarly, any increase in specificity achieved by a shift to the right will be more than offset by a decrease in sensitivity.
Increasing the injection volumes above this level led to a decrease in sensitivity and an increase of the column back pressure with final clogging.
PKCα-overexpressing resistant cells exhibited a decrease in sensitivity to cisplatin, whereas no significant change in sensitivity to BBR3464 was observed.
BLI negative lesions resulted not only in a decrease in sensitivity but obviously have also substantial contribution to non-optimal correlation of light signal and tumour size (Fig. 4).
Furthermore, as patients presented with more factors, there was an increase in the specificity and positive predictive value but a decrease in sensitivity and negative value of the guidelines for making a preoperative diagnosis of malignancy.
The protocol also advised rating the perceived strength of the library smell as soon as assessors entered the space, to prevent olfactory adaptation (a decrease in sensitivity after a period of exposure).
Setting the specificity level at 95% resulted in a decrease in sensitivity except for A. baumannii (it reached nearly 100%); it fell below 50% for three pathogens: around 40% for Streptococcus pneumoniae and Enterococcus faecalis and 25% for Enterobacter cloacae.
Ozone addition to cool flames is seen to lead to a substantial increase in the extinction limit, but it also produces a decrease in sensitivity of the extinction limit to the fuel mass fraction.
A pretest training posttest design was used to tap into the learning process, and development was predicted to occur mainly through increased sensitivity in the newly trained category boundary region, i.e. acquired distinctiveness, rather than through a decrease in sensitivity within the new categories, i.e. acquired similarity.
