Noise health effects are the physical and psychological health consequences of regular exposure to consistent elevated sound levels. Noise from traffic, in particular, is considered by the World Health Organization to be one of the worst environmental stressors for humans, second only to air pollution. [2]
There are some pieces of evidence that show a small correlation between environmental noise and reading and oral comprehension. [8] Environmental noise in children is most commonly by people around them whether that be siblings crying or friends screaming. Then children are mostly exposed to animal noises and traffic noise. [9]
[80] [81] This noise pollution significantly raises the low-frequency ambient noise levels above those caused by wind. [82] Animals such as whales that depend on sound for communication can be affected by this noise in various ways. Higher ambient noise levels also cause animals to vocalize more loudly, which is called the Lombard effect.
This industrial symphony may just seem like background din, considering that an estimated 1 in 3 Americans is exposed to “excessive noise levels,” but it can have very real health consequences ...
Comprehension difficulties can also be a result of hyperlexia. Semantics and comprehension both have ties to meaning. Semantics relates to the meaning of a certain word while comprehension is the understanding of a longer text. In both studies, interpretation-based and meaning-based tests proved difficult for the hyperlexic subjects.
Reading comprehension is a part of literacy. Some of the fundamental skills required in efficient reading comprehension are the ability to: [7] [8] [9] know the meaning of words, understand the meaning of a word from a discourse context, follow the organization of a passage and to identify antecedents and references in it,
The risk of negative health effects from sound exposures (be it noise or music) is primarily determined by the intensity of the sound , duration of the event, and frequency of that exposure. [9] These three factors characterize the overall sound energy level that reaches a person's ears and can be used to calculate a noise dose.
Workers in general industry who are exposed to noise levels above 85 dBA are required by the Occupational Safety and Health Administration (OSHA) to be in a hearing conservation program (HCP), which includes noise measurement, noise control, periodic audiometric testing, hearing protection, worker education, and record keeping. Twenty-four ...
