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.
1 The absolute threshold of human hearing is defined as 0 decibels. 2  Loudness doubles with every 10-decibel increase in amplitude. 3  Pitch, though influenced by amplitude, depends most on the frequency of sound waves.4  Frequency is the number of times per second a sound wave cycles from the highest to the lowest point.he physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. 1  Loudness depends on the amplitude, or height, of sound waves. 2  The greater the amplitude, the louder the sound perceived. 3  Amplitude is measured in decibels.
