This result suggests that the animals began to devalue the reward that they previously wanted, and focused more on the cost of the aversive stimulus.
There is little research that examines the direct assessment of noise as a potential aversive stimulus and subsequent development of function-based treatments.

When exposed to fear conditioning protocols, animals acquire fear memory through the association between conditioned stimuli--a tone, a smell, or a context--with an unconditioned aversive stimulus, usually a foot shock.
In contextual fear conditioning, experimental subjects are placed in an emotionally neutral context (such as a room) and presented an aversive stimulus (such as an electrical shock).
Counter-conditioning involves changing your dog's association with an aversive stimulus from negative to positive.
That is, when an aversive stimulus is presented or a reinforcing stimulus is withdrawn, the probability that the action will be repeated declines (Kunkel & Berry, 1968).

Conditioned fear in vertebrates such as rodents is often brought about by pairing an aversive stimulus (the US)--for example, an electric shock-- with a neutral stimulus (the CS)--for example, a tone (see Maren, 2001).
