sensing device‚ affected the way people sense energy? B. The hearing aid amplifies sound energy that comes into contact to the hearing aid. There are two types of hearing loss. 1. Sensorial hearing loss. This hearing loss is caused by damage to the cochlea‚ infections‚ genes‚ head trauma‚ exposure to loud noises or fluid buildup in the inner ear. This is the hearing loss that hearing aids can help with. 2. Conductive hearing loss. This occurs when sound does not move as it should through the eardrum

In the video there were several different illusions that showed us how one’s perception can be easily manipulated. One showcase was about the “crazy nuts”‚ which showed two perpendicular nuts that seemed to be moving or sliding across each other‚ when in actuality‚ the notes were rotating. Each time the movement occurred our minds had a momentary lapse before realizing what was truly happening in the illusion. I found two optical illusions enjoyable. One was about the manipulation on shapes. In

nonrotational vestibular symptoms. This physical distention causes mechanical disturbance of the organ of Corti as well. Distortion of the basilar membrane and the inner and outer hair cells may cause hearing loss and/or tinnitus. Since the apex of the cochlea is wound much tighter than the base‚ the apex is more sensitive to pressure changes than the base. This explains why hydrops preferentially affects low frequencies (at the apex) as opposed to high frequencies (at the relatively wider base). Symptoms

Labyrinthitis is a disorder of the inner ear. The membranous labyrinth of the sensory organs; such as the saccule‚ utricle‚ cochlea‚ and semicircular canals‚ are invaded by infectious microorganisms and damage the vestibular and auditory organs. (Boston‚ 2015) The vestibular nerves‚ of the inner ear‚ can also become inflamed and cause vertigo and dizziness. (Campellone‚ 2015) Vertigo is described as “feeling as if the room is spinning.” (Dizziness and vertigo‚ 2016) Equilibrium‚ a special sense‚

attribute‚ an owl can turn its head completely backwards! This allows it to still see all around. Another special characteristic of the owl that makes them excellent night hunters is their acute hearing abilities. Owls have very large ear openings and cochlea that are covered by feathers. One ear is even higher than the other so that the owl can turn its head to make a sound’s intensity equal and thus hone in on where the sound is coming from. Even their feathers have adapted to assist in the hearing of
