Feilding, Charles.Lecture 007 Hearing II(англ.). College of Santa Fe Auditory Theory. — «The peak sensitivities shown in this figure are equivalent to a sound pressure amplitude in the sound wave of 10 μPa or: about -6 dB(SPL). Note that this is for monaural listening to a sound presented at the front of the listener. For sounds presented on the listening side of the head there is a rise in peak sensitivity of about 6 dB [−12 dB SPL] due to the increase in pressure caused by reflection from the head.» Дата обращения: 17 марта 2016.

Jones, Pete R.What's the quietest sound a human can hear?(англ.). University College London (20 ноября 2014). — «On the other hand, you can also see in Figure 1 that our hearing is slightly more sensitive to frequencies just above 1 kHz, where thresholds can be as low as −9 dBSPL!» Дата обращения: 16 марта 2016.
