Mas Yus Health. Did you know that the sound of laughter is not captured by the ear with the same people around him. However, the kind of laughed out loud with your mouth open would be arrested in a positive way by the listener. Even someone else will come along to feel the same excitement.
In a study of the effects of a laugh, the experts found that a hearty laugh, to produce the sound "ha ha ha", has the effect of "contagious". Michael Owen from Georgia State University and Tobias Riede from the University of Utah, both researchers laugh, make comparisons between the effects of a hearty laugh with a laugh that made with the mouth closed or half open.
The study involved 28 students who were asked to rate 48 sound recordings of various different types of laughter. Namely laugh with his mouth wide open with his mouth half open.
The students were assessing all the laughter it positively, but they gave the highest value of the sound generated from the type of laugh out loud or with his mouth wide open.
In general, the stronger vibrations and vocal in the laughter, the stronger the effect of "transmission" to make other people who hear it to laugh.
Experts suspect, when listening to the sound of laughter out loud, the imagination of people who hear it carried on and imagine things that are funny so hooked to laugh. This is also called desire to laugh.
