Acoustic shock is the set of symptoms a person may experience after hearing an unexpected, loud sound. The loud sound, called an acoustic incident, can be caused by feedback oscillation, fax tones, or signalling tones. Telemarketers and call centre employees are thought to be most at risk. [1]
Symptoms may include a sense of fullness in the ear, tinnitus, and dizziness. [7] [8] The model details how symptoms may be initiated by tensor tympani muscle damage or overload due to acoustic shock or trauma. Hypercontraction or hyperactivity of the muscle may cause an "ATP energy crisis." The muscle is then forced to create energy without ...
Acoustic trauma is the sustainment of an injury to the eardrum as a result of a very loud noise. Its scope usually covers loud noises with a short duration, such as an explosion , gunshot or a burst of loud shouting.
Evidence has shown that when children learn in noisier classrooms, they have more difficulties understanding speech than those who learn in quieter settings. [ 49 ] In a study conducted by Cornell University in 1993, children exposed to noise in learning environments experienced trouble with word discrimination, as well as various cognitive ...

An acoustic signal from a sound source, such as a radio, enters into the external auditory canal (ear canal), and is funneled through to the tympanic membrane (eardrum), causing it to vibrate. The vibration of the tympanic membrane drives the middle ear ossicles , the malleus, incus, and stapes to vibrate in sync with the eardrum.
There are a wide variety of symptoms that have been found to be associated with sensory overload. These symptoms can occur in both children and adults. Some of these symptoms are: Irritability "Shutting down," or refusing to participate in activities and interact with others; Over-sensitivity to touch, movement, sights, or sounds
A minor bump to the head is the most commonly reported precipitant. Usually the toddler trips and falls; the child's caregiver may hear the bump. Most commonly, the child does not cry, although some parents give descriptions of the child "trying to cry" (Stephenson 1978), or there may be a gasp or a sob. Syncope rapidly ensues.
