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 ...
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
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.

The same "protective effect" was also observed with other stressors such as heat-shock conditioning [116] and stress (by restraint) conditioning. [117] This "protective effect" only happens if the traumatizing noise is presented within an optimum interval of time after the sound-conditioning session (-24 hours for a 15 min. sound-conditioning ...
The role of the BNST in the acoustic startle reflex may be attributed to specific areas within the nucleus responsible for stress and anxiety responses. [12] Activation of the BNST by certain hormones is thought to promote a startle response [12] The auditory pathway for this response was largely elucidated in rats in the 1980s. [14]
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
