Ha-ha-ha, hi-hi-hi, tee-hee-hee, bwah-hah-hah, yuk-yuk-yuk-yuk-yuk, mu-ha-ha-ha-ha-ha….these are just some of the different sounds people make when they laugh. Of course the last one sounds more like malevolent laughter that comes out of an evil character’s mouth; but it is still laughter just the same. Some believe that laughter is the universal language of man. Regardless of race or creed, everyone enjoys a good laugh.
Laughter is the sound one makes as a reaction to a particular stimulus. Usually, it comes about due to amusement and during merriment. It is also common for people to laugh as a result of stress, fear or nervousness. Laughter is one faculty that some human’s use to regain balance when there is anxiety, tension, or pressure around them. Hyenas use laughter this way, too.
