Otoacoustic emissions (OAE) testing is often used to check newborns for hearing problems. In this test, a small, soft microphone is placed in the baby's ear canal. Sound is then sent through a small flexible probe that has been put in the baby's ear. The microphone detects the inner ear's response to the sound.
The range of human hearing is generally considered to be 20 Hz to 20 kHz, but it is far more sensitive to sounds between 1 kHz and 4 kHz. For example, listeners can detect sounds as low as 0 dB SPL at 3 kHz, but require 40 dB SPL at 100 hertz (an amplitude increase of 100).
