The principle behind Teen Buzz is a biological reality that audiologists can refer to as presbycusis, or aging ear. Starting at around age 20, scientists say, the human ear loses its ability to hear tones in the highest human-range frequencies (18-20 kHz), and as one ages, it becomes more difficult to detect these sounds.
