Logarithmic chart of the hearing ranges of some animals [1] [2] Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high ...
The only bird known to make use of infrasound (at about 20 Hz) is the western capercaillie. [48] The hearing range of birds is from below 50 Hz to around 12 kHz, with maximum sensitivity between 1 and 5 kHz. [22] [49] The black jacobin is exceptional in producing sounds at about 11.8 kHz. It is not known if they can hear these sounds.
The surface of the flight feathers is covered with a velvety structure that absorbs the sound of the wing moving. These unique structures reduce noise frequencies above 2 kHz, [20] making the sound level emitted drop below the typical hearing spectrum of the owl's usual prey [20] [21] and also within the owl's own best hearing range.
Generally, birds have been assessed to vocalize and hear in the range of 2–5 kHz, with hearing sensitivity falling with higher frequencies. [85] In the Ecuadorian hillstar (Oreotrochilus chimborazo), vocalizations were recorded in the wild to be at a frequency above 10 kHz, well outside of the known hearing ability of most birds. [85]

This study went further to show that the removal of these kinds of feathers also has an influence on the ITD and ILD in owls’ hearing. The most influential feathers were the reflector feathers, as the removal of these feathers showed to make the owls’ ears more sensitive and selective, and it also extended the physiological range of the ITD ...
