Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. The academic field concerned with hearing is auditory science. Sound may be heard through solid, liquid, or gaseous matter.The ear is the organ of hearing and balance. The parts of the ear include: External or outer ear, consisting of: Pinna or auricle. External auditory canal. Tympanic membrane (eardrum). Middle ear, consisting of: Ossicles: Malleus, Incus, Stapes. Eustachian tube. Inner ear, consisting of: Cochlea. Vestibule. Semicircular canals. Hearing range is measured in Hertz (Hz). When hearing ability is tested, a range of 250 Hz to 8000 Hz is measured because it encompasses the speech frequencies, the most important the range for communication.An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer. The Y axis represents intensity measured in decibels and the X axis represents frequency measured in hertz. Hearing range of animals is from 10 Hz to 100000 Hz. Healthy hearing spiders are most sensitive to low frequency sounds and can hear by using tiny hairs on their forelegs. Hearing range varies by species; at the lowest it can be 1 kHz for some species and for other species the highest reaches up to 200 kHz. Bats that can detect 200 kHz cannot hear very well below 10 kHz.
