Loud noise can create physical and psychological stress, reduce productivity, interfere with communication and concentration, and contribute to workplace accidents and injuries by making it difficult to hear warning signals.

Does noise affect memory?
Non-auditory tasks such as short-term memory, reading and writing are also impaired by noise. Depending on the nature of the tasks and sounds, these impairments may result from specific interference with perceptual and cognitive processes involved in the focal task, and/or from a more general attention capture process.
Is Misophonia a mental illness?
The diagnosis of misophonia is not recognized in the DSM-IV or the ICD 10, and it is not classified as a hearing or psychiatric disorder. It may be a form of sound–emotion synesthesia, and has parallels with some anxiety disorders.
Are noisy restaurants harmful to your health?

Can constant noise make you sick?
and man-made. Some studies have shown that at high intensities, infrasonic sounds can have extra-aural bioeffects, including nausea, headaches, and dizziness, but why? The short answer: bad vibrations. Sound is a wave of pressure traveling through a medium.
Is white noise harmful?

What sound frequency is harmful to humans?
Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing. However, sounds under the frequency of 20 Hz can also affect the ear even though we are unable to hear them.
Why are restaurants so noisy?
Restaurants are so loud because architects don’t design them to be quiet. Much of this shift in design boils down to changing conceptions of what makes a space seem upscale or luxurious, as well as evolving trends in food service.

90 dBAWith noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. Occupational standards specify a maximum allowable daily noise dose, expressed in percentages.
Can noise damage your brain?
Summary: Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists. Exposure to intensely loud sounds leads to permanent damage of the hair cells, which act as sound receivers in the ear.
