For example, the sound of fingernails scratching a blackboard will stimulate negative emotions along with chills in the majority of the population. Trevor J. Cox, of the University of Salford, was fascinated by this fact and conducted an online study to identify the "most horrible sound" in the world. Participants were asked to listen to ...
Misophonia (or selective sound sensitivity syndrome) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues.These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses not seen in most other people.

In January 2024, BMJ Public Health published a systematic review of 14 studies investigating associations between sound-induced hearing loss and playing video games and esports that found a significant association between gaming and hearing loss or tinnitus and that the average measured sound levels during gameplay by subjects (which averaged 3 ...
In contrast, humans are less averse to the white noise than to scraping. [4] A 1986 study used a tape-recording of a three-pronged garden tool similar to a fork being "grided" across a chalkboard, which roughly reproduces the sound of fingernails on chalkboard. The recording was then manipulated, removing pitches at the extremities and the median.
Earmuff HPDs typically consist of two ear cups and a head band. [56] Earplug style hearing protection devices are designed to fit in the ear canal. Earplugs come in a variety of different subtypes. [56] Some HPDs reduce the sound reaching the eardrum through a combination of electronic and structural components. Electronic HPDs are available in ...
The stereocilia (hair cells) of the inner ear can become subjected to bending from loud noises. Because they are not regeneratable in humans, any major damage or loss of these hair cells leads to permanent hearing impairment and other hearing-related diseases. [2] Outer hair cells serve as acoustic amplifiers for stimulation of the inner hair ...
Donald Trump’s ear appears to have come out relatively unscathed from the July 13 attempt on his life during a rally in Butler, Pennsylvania, according to a reporter who recently sat down with ...
The human ear can nominally hear sounds in the range 20 to 20 000 Hz. The upper limit tends to decrease with age; most adults are unable to hear above 16 000 Hz. Under ideal laboratory conditions, the lowest frequency that has been identified as a musical tone is 12 Hz. [6] Tones between 4 and 16 Hz can be perceived via the body's sense of touch.
