A setback is a temporary exacerbation of symptoms, a worsening of the perception of loudness or pain from sound, often due to a particular noise exposure. [12] Setback prevention is an important focus among those affected. Efforts to avoid setbacks commonly include using hearing protection and avoiding loud noises. [17]
Phonophobia, also called ligyrophobia or sonophobia, is a fear of or aversion to loud sounds (for example firecrackers)—a type of specific phobia. [2] It is a very rare phobia which is often the symptom of hyperacusis. Sonophobia can refer to the hypersensitivity of a patient to sound and can be part of the diagnosis of a migraine.
Acoustic trauma is an injury to the inner ear that's often caused by exposure to a high-decibel noise. This injury can occur after exposure to a single, loud noise or from exposure to noises at significant decibels over a longer period of time. [medical citation needed] Many cases have included a period of reduced hearing after exposure to loud ...
Exposure to a single very loud noise such as a gun shot or bomb blast can cause noise-induced hearing loss. Using headphones at high volume over time, or being in loud environments regularly, such as a loud workplace, sporting events, concerts, and using noisy machines can also be a risk for noise-induced hearing loss.
Noise-induced threshold shifts are seen as a notch on an audiogram from 3000 to 6000 Hz, but most often at 4000 Hz. [16] Exposure to loud noises, either in a single traumatic experience or over time, can damage the auditory system and result in hearing loss and sometimes tinnitus as well. Traumatic noise exposure can happen at work (e.g., loud ...
Hearing: loud noise, or sound from multiple sources, such as several people talking at once. Sight: crowded or cluttered spaces, bright lights, strobing lights, or environments with much movement such as crowds or frequent scene changes on television. Smell and taste: strong aromas or spicy foods.
During extreme cold events, you may hear a loud boom and feel like you have experienced an earthquake. However, this event was more likely a cryoseism, also known as an ice quake or a frost quake ...
Others, such as ISO 532A (Stevens loudness, measured in sones), ISO 532B (Zwicker loudness), DIN 45631 and ASA/ANSI S3.4, have a more general scope and are often used to characterize loudness of environmental noise. More modern standards, such as Nordtest ACOU112 and ISO/AWI 532-3 (in progress) take into account other components of loudness ...
