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.
It is the sound quality most closely related to the frequency of a pure tone. High-frequency tones are perceived as being of high pitch while low-frequency tones are said to be of low pitch. The relationship between pitch and frequency is however, not a simple linear one.In order to investigate how the two are related, pitch has been assigned the arbitrary unit the mel. The pitch of a 1000 Hz tone at 40 dB SPL has been given a fixed value of 1000 mel.igh-frequency tones are perceived as being of high pitch while low-frequency tones are said to be of low pitch.
