The following experiment was done to test the effects of water temperature on vocal ranges. Twenty subjects were first tested to find their vocal range with no water, then they would intake warm water and cold water at separate times to determine if their were any changes. The females were able to have an increase in their vocal range with cold water. While the males increased in their vocal range with just the intake of water.

I. Introduction
There are many theories as to how water temperature may seem to have an effect on a person’s vocal range. For example, Deirdre D. Michael the writer of the article from Lions Voice Clinic states the myth and facts about the effects of water temperature on vocal range. Michael debunks the myth “Water …show more content…
A series of test will be completed in order to measure and observe the subjects vocal range without any water intake. The independent variable will consist of two different water temperatures, one warm the other cold. The ultimate objective is to result with qualitative and quantitative data that will determine whether or not water temperature affects a person’s vocal range.
If water temperature affects vocal range, then a person’s range will alter due to the independent variable. Although there may be the factor that “If cold beverages make you feel cold, and that makes your muscles more tense.” (Lions Voice Clinic) Michael’s idea that if a person believes water temperature may affect their vocal range then that will become the ultimate results of the data.
In order to test whether or not a person’s vocal range is affected by water temperature, twenty test subjects were used to determine the results. Ten were female and the other ten were male. First, a person’s vocal range without water temperature to affect their results will be tested, this will be their control. The person will go up and down an octave on the piano. The piano will be used to determine their vocal range. The independent variable will be the cold and warm temperature …show more content…
The data contradicts the theory that “…cold water can have a numbing effect on the throat.” (Caring For Your Voice). If this statement were true than the data reveals, the problem would be the order the subject drank the water. Order would be the underlying cause for the numbers to fluctuate and contradict previous research done to determine the effects of water temperature on vocal range. In Figure 1 the data does not appear to change much, but the cold water still tends to yield the better results. The warm temperature water in Fig. 1 and 2 seem to have little to no affect as opposed to the cold water, on the female subjects. The fact from Lions Voice Clinic can also play a part in the belief that someone believes the cold water will cause the test subjects larynx to tense (Lions Voice Clinic). None of the subjects were aware which temperature would yield them better results, so this did not cause the female subjects to believe that the cold water would tense their
