In this image, the introduction reads as follows: Side effects of lifesaving drugs given to the triplets as newborns eventually led to deterioration of the inner ear, home of the delicate structures where vibrations are converted to electrical and chemical signals that the brain understands as sound. Without this conversion, sound waves may enter the ear, but we do not “hear.” Hearing is a process in which stimuli (sound waves) are mechanically converted to vibrations that are transduced to neural messages. If one part of this complicated system is compromised, hearing loss results. The main graphic shows the structures of the ear in a cross-section, divided into the outer ear, middle ear, and inner ear, with a magnified graphic of a part of the inner ear. The cross-section shows sound waves collected by the outer ear, labeled “Pinna” traveling down the Auditory canal to the Ear drum. A callout reads, “1. The pinna funnels sound waves into the auditory canal, focusing them toward the eardrum.” To the right of the ear drum is the middle ear, made up of three small bones. The first bone is labeled “Hammer,” and is hammer shaped and connected to an L-shaped bone labeled “Anvil,” which is in turn connected to a stirrup-shaped bone labeled “Stirrup.” The callout reads, “2. Vibrations of the eardrum cause hammer to push anvil, which moves stirrup, which presses on oval window, amplifying waves.” The stirrup sits next to the inner ear, shaped like a swirl with three loops at the top, shown in a magnified image. The stirrup sits against an oval structure on the side of the inner ear, labeled “Oval window.” The callout reads, “3. Pressure on oval window causes fluid in cochlea to vibrate.” In the magnified view, a cutaway cross-section shows rows of membranes, labeled “Basilar membrane,” next to hair-like projections called “Hair cells.” The callout reads, “4. Vibrating fluid in cochlea bends hair cells on basilar membrane, triggering action potentials in the auditory nerve.” Nerve fibers arise from the hair cells, labeled “To auditory cortex in brain.” The callout reads, “5. Auditory nerve carries signals to auditory cortex in brain, where sounds are given meaning.” The lower section of the infographic is titled, “Decibels and Damage.” The introduction reads: The intensity of a sound stimulus is measured in decibels (dB). The absolute threshold for human hearing—the softest sound a human can hear—is described as 0 db. Loud noises, such as the 140 dB produced by a jet engine, cause immediate damage leading to hearing loss. Chronic exposure to moderately loud noise, such as traffic or an MP3 player near maximum volume, can also cause damage (Keith, Michaud, & Chiu, 2008).A spectrum graph shows sound in decibels from 0 at the left to 140 at the right. A label to the 0 dB mark reads, “Absolute threshold.” A label to the 80 dB mark reads, “Continual exposure may cause damage.” A label to the 125 dB mark reads, “Hearing becomes painful.” Several images and callouts are shown across the spectrum, including the following:
