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.
How is pitch or frequency determined? Range of hearing: 20-20,000 Hz. Range in volume 10 6! Sound processing is very complex and involves positive feedback. Feedback enhances sensitivity, but can go above one and ear starts vibrating by itself. The ear actually produces a tone â this is the ringing in your ear. 1  Basilar membrane resonates when a sounds wave enters: Different parts resonate at different frequencies. 2  Resonant frequencies are spaced logarithmically â like a piano. 3  A single input frequency can activate a range of nerves on the Basilar membrane:
