Hospital corpsmen were previously trained at Naval Hospital Corps School, Great Lakes, Illinois until the 2011 Base Realignment and Closure Bill caused Hospital Corps School to be relocated to the Medical Education and Training Campus (METC) at Joint Base San Antonio, Texas.
characteristic of highness or lowness of a sound is called The frequency of a sound wave determines the pitch of the sound you hear. Remember that frequency is the number of waves passing a fixed point in a given period of time. A high-frequency wave with short wave-lengths, such as that produced by a tiny flute, makes a high-pitched sound.
The amplitude of a sound wave determines it's pitch frequency loudness wavelength. Answers.com says: The pitch or note of a sound that we experience is determined by its wavelength or its frequency. The shorter the wavelength, the higher the frequency becomes, and the higher the pitch that we hear. The amplitude of a sound wave is the same thing as loudness. The loudness or amplitude corresponds to how much the wave is compressed. The wavelength of a wave is independent of its amplitude [loudness] and inversely proportional to its frequency. ~~ JUST so im not using some1 else'z work with out letting u know.
