... – Pitch is determined by frequency hair cells produce action potentials – If the frequency of the sound is 100 waves per second then the neuron fires at 100 pulses per second. – But we can hear frequencies above 1000 waves per second but can’t fire neurons faster than 1000 pulses per second. – Volle ...

Ear
The ear is the organ that detects sound. It not only receives sound, but also aids in balance and body position. The ear is part of the auditory system.Often the entire organ is considered the ear, though it may also be considered just the visible portion. In most mammals, the visible ear is a flap of tissue that is also called the pinna (or auricle in humans) and is the first of many steps in hearing. Vertebrates have a pair of ears placed somewhat symmetrically on opposite sides of the head. This arrangement aids in the ability to localize sound sources.
