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.
Lesson Summary. According to the frequency theory of hearing, the frequency of the auditory nerve's impulses corresponds to the frequency of a tone, which allows us to detect its pitch. Sounds come into the ear as acoustical signals and are later transformed into nerve impulses by the cochlea. The auditory nerve transfers these nerve impulses to the brain. Frequency theory of hearing can only account for sounds up to 5,000 hertz. The place theory of hearing accounts for sounds at or above 5,000 hertz.
