Background Information

There are certain noises that nearly all humans would agree sounds highly aversive and results in action to try and get away from the unpleasant sound. In a complex and rapidly changing environment, evolutionarily adaptive behavior requires that such sensory information be extracted and processed more efficiently for stimuli that are emotionally salient. There was in fact a study published in 2012 that tried to determine the most aversive sounds from a neurological basis using a fMRI machine. According to the study, the top 10 most aversive sounds which were evaluated in rank order:

  • A knife on a bottle
  • A fork on a glass
  • Chalk on a blackboard
  • A ruler on a bottle
  • Nails on a blackboard
  • A female scream
  • An angle grinder (a power tool)
  • Squealing brakes on a bicycle
  • A baby crying
  • An electric drill
