Sound can be defined as energy or the transfer that is propagated from one place to another in this type of motion
What is wave like?
This outer ear structure has a unique curved shape with grooves and ridges that act as a funnel, collecting sound from all directions, while also filtering background noise and selectively enhancing certain sounds
What is the pinna?
Located at end of the EAM and vibrates in response to sound
What is tympanic membrane?
Considered the sensorineural system of hearing
What are the cochlea and cochlear branch of CN VIII?
Absence of pinna
What is anotia?
Pattern that is formed from the displacement of air particles
What is vibratory motion?
The size and structure of this outer ear structure is important to its function in the transmission of sound energy from the outer ear to the middle ear
What is the external auditory meatus (EAM)?
The ossicular chain functions as this.
What is a lever?
Movement of the ossicles stimulates this window to compress the perilymph of the scala vestibuli of the inner ear
What is the oval window?
An acquired disorder due to trauma to the outer ear 
What is cauliflower ear?
This is measured as the number of vibratory cycles that occur in a specified unit of time
What is frequency?
Created in the first one-third of the EAM
What is cerumen or ear wax?
These structures vibrate in response to the eardrum, and the stapes then pushes on the oval window of the inner ear, converting sound waves into fluid waves.
What are the ossicles (incus, stapes, and malleus)
These are important for hearing and balance because they bend in response to sound
What are hair cells (stereocilia)?
Inflammation of the middle ear (undrained fluid, swollen Eustachian tube)
What is otitis media?
Range of loudness that the average human can hear
What is 0 to 140 dB SPL?
Prevents water from entering the ear canal and expel dirt and dead skin cells from the epithelial lining of the EAM
What are cilia and cerumen?
The process by which the middle ear converts low-pressure sound waves in the air into high-pressure vibrations in the inner ear's fluid
What is transformer action?
This process is when the brain interprets and uses sounds sensed by the ear, especially speech sounds, to make sense of the environment
What is auditory processing?
Bony tumors in the ear canal 
What is osteoma?
Frequency is represented by this symbol
What is Hertz (Hz)?
Term for when the pinna dampens sounds due to its shape
What is selective enhancement?
Serves to equalize the pressure of the middle ear with the atmospheric air pressure
What is Eustachian Tube?
This part of the inner ear processes information about body position and acceleration in space
What is the vestibular system?
Surgical procedure that allows for pressure equalization in the middle ear
What is myringotomy?
