The Auschwitz concentration camp complex was the largest of its kind established by the Nazi regime. It included three main camps. All three camps used prisoners for forced labor. One of them also functioned for an extended period as a killing center. The camps were located approximately 37 miles west of Krakow.
The frequency of a sound wave determines what people hear as pitch. A higher frequency has a higher pitch, and a lower frequency is heard as a lower pitch. The frequencies that humans can hear range from 20 to 20,000 Hertz. Continue Reading.
Sound waves are longitudinal waves that require a medium in which to travel. The medium consists of particles that oscillate within a certain amplitude. The amplitude of a sound wave is a reflection of how much energy is carried, which contributes to the intensity of the sound. Intensity is measured in decibels and is perceived as sound volume. Thus, the volume is proportional to the amplitude of the sound wave. The frequency of a sound wave is perceived as pitch. Humans can detect pitches within the acoustic range of 20 to 20,000 Hz, but we can't detect ultrasound or infrasound.
