They noted: 'When listening to natural sounds, the brain connectivity reflected an outward-directed focus of attention; when listening to artificial sounds, the brain connectivity reflected an inward-directed focus of attention, similar to states observed in anxiety, posttraumatic stress disorder, and depression. '
the inner ear translates vibrations into electrical signals.the electronic signals are carried into the brain by nerve cells called neurons via the signals travel along the cochlear nerve system to the brains cerebral cortex. like a super computer, this part of brain
The human ear does not make a sound, it only receives it.
By shock waves synapsing through ears and turtles in an ocean communicating through the balls of your body
Due to conduction deafness.
Outer ear
the pinna is like an ear trumpet that funnels sounds into the ear canal..
Sounds greater than 90 dB can be harmful to the human ear. Rock concerts average about 110 to 120 decibels. A jet plane taking off measures from 120 to 160 decibels.
Ears have two uses. First, mainly for hearing and receiving sound waves and the second one is for the body balance and equilibrium

Mosquitoes make sounds near the human ear because mosquitoes make sounds everywhere. It sounds as though the mosquitoes are purposely seeking out the human ear when in reality, we only hear them when they're close.
The human ear cannot detect all possible frequencies. It has evolved to detect frequencies of sounds that are the most useful to humans, and has a maximum frequency range of about 20Hz to 20kHz, which decreases as you get older, particularly at the higher end. Infrasonic describes sounds that are too low in frequency to be heard by the human ear, and ultrasonic describes sounds that are too high in frequency to be heard by the human ear. These sounds cannot be heard by the human ear because they are outside of its range of capability.
Due to conduction deafness.
Ultrasound.
we know that human ear can not hear sounds of frequency less than 20Hz or more than about 20,000 Hz . Sounds of frequency higher than 20,000 Hz , which are inaudible to human ear, can be produced and are utilized in many useful ways. Such sounds are called ultrasonics
It's a part of the "transducer" that converts air sounds (large, low pressure) into liquid sounds (low amplitude, high pressure) - it connects the ear drum to the inner ear (a thin section of the skull.

The giraffe makes to little sounds to hear with the human ear
It is difficult to say how far the human ear can pick up sounds. The distance a human ear can hear varies according to the condition of the ear, the frequency of the sound, and other sounds taking place at the same time.
the human percieves colour code is yellow
