Two studies published in the Journal of the Acoustical Society of America (2008, 2012) examined the responses of multiple groups of students at Newcastle University who listened to preselected groups of different sounds. The students’ responses were used to determine the most annoying sounds in the world for human beings – the top five of which are presented in this exhibition.
Originally our Summer 2020 Blockbuster Exhibition, due to popular demand we have now made The 5 Most Annoying Sounds In The World a permanent exhibition – which means you can visit it at any time!
Each of the five most annoying sounds is an example of a gride: a grating, grinding, or scraping noise. These types of sounds have been the subject of previous studies of annoyance, but in the 2008 study they were, for the first time, intermixed with other types of sounds including human and animal vocalisations, weather sounds, musical instruments, and machines. The griding sounds proved once again to be the most annoying sounds of the bunch.
Human reactions of annoyance to sounds is thought to be controlled by the amygdalae, two small, acorn-shaped clusters of nuclei, one located in each hemisphere of the brains of humans and other mammals. The amygdalae communicate with other portions of the brain to form emotional responses and memories, but are also believed to be involved in a surprising number of other experiences such as anxiety, social interaction, sexual orientation, alcoholism, post-traumatic stress disorder, and even political orientation.
Our exhibition presents the five most annoying sounds in the world – the same recordings used in the studies – each played over and over again for exactly one minute, beginning with the least annoying and ending with the scientifically determined Most Annoying Sound in the World.

Researchers found that unpleasant sounds range between 2000 and 5000 Hz, where human ears are most sensitive. Some everyday sounds in that range may include car alarms, squeaky doors, high-pitched screeching, crying children, and more. Even loud snoring or chewing noises can be disturbing for sensitive people.
We're all bothered by different noises, but some of the most hated sounds include loud chewing, babies crying and snoring. There's little research into what causes noise sensitivity, but it's thought to be down to the way the brain functions, rather than being a hearing problem.
On May 20, 1883, Krakatoa, a volcano on Rakata Island in Indonesia, erupted with a force never seen—or heard—on Earth. The sounds of the eruption of the Krakatoa volcano were estimated to be 310 dB SPL, and there are reports that it was heard some 1 , 300 miles away in the Bay of Bengal.
Problematic sounds for younger children tend to be loud and unpredictable, such as the hand dryer or self-flushing toilets in public restrooms, or the vacuum or blender at home. For a hyperacusic child, the school day can be ruined by a fire drill.
Misophonia is a disorder in which certain sounds trigger emotional or physiological responses that some might perceive as unreasonable given the circ*mstance. Those who have misophonia might describe it as when a sound “drives you crazy.” Their reactions can range from anger and annoyance to panic and the need to flee.
Sounds that reach 85 decibels or higher can harm a person's ears. Sound sources that exceed this threshold include familiar things, such as power lawn mowers (90 decibels), subway trains (90 to 115 decibels), and loud rock concerts (110 to 120 decibels).
The first 10 pleasant sounds were those of a brook, a wave, a wind bell, a music box, a Japanese nightingale, a "bell-ring" insect, the chirp of birds, rhythmic sounds, classi- cal music, and the song of birds. S.
The threshold of hearing is generally reported in reference to the RMS sound pressure of 20 micropascals, i.e. 0 dB SPL, corresponding to a sound intensity of 0.98 pW/m2 at 1 atmosphere and 25 °C. It is approximately the quietest sound a young human with undamaged hearing can detect at 1,000 Hz.
Tinnitus is common. Almost everyone notices a mild form of tinnitus once in a while. It usually lasts a few minutes. However, constant or recurring tinnitus may be stressful and may make it harder to focus or sleep.
In addition, exposure to impulse noise (abrupt high intensity sounds of short duration [e.g., whistles, horns, cannon blasts, fireworks]) should never exceed a peak sound pressure of 140 dB peak in adults, and 120 dB in children.
Other studies have found screeching and scraping sounds to be very unpleasant, with the archetypal example being fingernails scraping down a blackboard.
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
(B) OBNOXIOUS NOISE is any noise noxious enough to destroy the enjoyment of residents or other uses of property in the vicinity interfering with the ordinary comforts of human existence, including, but not limited to: (1) Horns, signaling devices.
