- Abstract
- When we climb the high mountain, we yell 'Ya-ho'. However, it is a noise pollution that gives damage to the creatures living in the mountain to shout loudly 'Ya-ho' on the mountain. The actual meaning of 'Ya-ho' is a global common rescue signal that requests rescue in voices at close range. There are so many words to ask for a rescue. However, 'Ya-ho' sounds very loud and can be heard relatively well. In this paper, we tried to find out how far 'Ya-ho' could be heard by comparing and analyzing several words that request rescue. As a result of the sound analysis, 'Ya-ho' has a very simple phoneme configuration, which makes the mouth wide open and loud. As the voice is opened wide, the pronunciation becomes clear, the tone frequency of the voice becomes high, and the harmonics become clear to the high frequency. In addition, 'Ya-ho' sound composition is very simple, and the frequency component is clear up to the 4KHz band, so it is easy to understand it as 'Ya-ho' even if it sounds small from far away. This 'Ya-ho' is very suitable as a rescue signal because of its ability to recognize 'Ya-ho' from far away. © International Research Publication House.
