Sounds of Communication

The sounds that animals use to communicate with each other have uniformity. The sounds are different with each species of course, atleast I would hope there were no barking birds out there. With any one animal type there is a universal language, that includes a number of common sound patterns. This allows for the various groups of canines to understand each other. Also for humans and other animals to gather a great deal of information from the signals used. The basics of the sounds are: Pitch, Duration, and Frequency

Pitch:
  • Low pitched sounds usaully indicate threats, anger, and possible aggression.
  • Hig pitched sounds mean the opposite.
  • A growl is meant to warn someone away
  • A dog that is going to attack will not give a vocal signal

signs of attack:

  • Dog may growl at first but once it realizes its warning is not being accepted it will stop the growl.
  • Its head will slighty lower
  • Its curled lip may tremble
  • and then a lunge
  • and a SNAP!

once the fight has started the growling may return.

In both cases of Fear and Anger sounds no longer serve as communication so they stop.

Duration:

Duration is used to modify the meaning of sounds.

  • shorter sound durations are associated with higher intensity fear, pain, or need.

ex: A yelp is a short duration of a whine

  • Longer durations become a whimper meaning pleasure, playfulness, or invitation.
  • The longer the sound the more likely the dog is making a concious descision about the nature of the signals and the behaviors about to follow.
  • A dominate dog will have a low growl, threatening display and will have every intention of standing its ground.
  • Growling in short bursts and held briefly indicates that fear is present.

Repition:

  • Sounds repeated often at a fast rate indicate excitment adn urgency.
  • Sounds spaced out indicated low level of excitment or passing stae of mind.
  • Occasional barking indicates mild intrest in something.
  • Multiple bursts adn repititionof barking indicates that the dog thinks the situation is important and a possible crisis.
