Will long-term noise environment affect hearing?
There will be damage! And both physically and mentally! Working in a noisy environment for a long time not only affects physical and mental health, but also affects social harmony. The most serious impact is actually on our hearing system. If the sound is not very loud, it will mainly cause psychological depression, make it difficult to concentrate, and make you easily irritable; if the sound is very loud, it will directly damage hearing, cause irreversible damage, and become a true "heir of deafness."
Being exposed to a noisy environment for a long time will definitely have an impact on hearing. Usually people with a history of noise are accompanied by tinnitus, and the hearing test curve will show an obvious sharp drop at 3000HZ and 6000HZ. Remember to form a "V" shape. Noise environments should be avoided in life and work, and if necessary, wear anti-noise earplugs to protect hearing.
Working in a noisy environment for a long time will reduce work efficiency and damage hearing. , causing insomnia, inducing various diseases, etc.
01. Reduced work efficiency
Environmental noise in open offices will lead to reduced employee work efficiency. Noise of all kinds can lead to a decline in employees' memory and recall abilities, as well as a reduction in basic skills such as simple calculations. Researchers say distraction is a big factor, but more importantly, noise in large open-plan offices can lead to increased employee stress.
02. Hearing damage
If people work in a strong noise environment for a long time, auditory fatigue cannot be recovered in time, and organic lesions will occur in the inner ear organs, which will form a permanent hearing threshold shift. , also known as noise-induced deafness. If a person is suddenly exposed to an extremely strong noise environment, the hearing organ will undergo severe trauma, causing tympanic membrane rupture and bleeding, labyrinth bleeding, and acute detachment of the spiral organ from the basilar membrane, which may cause the person's ear to completely lose hearing, that is, blast deafness.
03. Induce various diseases
Because noise acts on the central nervous system of the brain through the auditory organs, affecting all organs of the body. Therefore, in addition to causing damage to human hearing, noise can also cause Bring harm to other human systems. Due to the effect of noise, neurasthenic symptoms such as headache, brain swelling, tinnitus, insomnia, general fatigue and memory loss will occur.
04. Causes insomnia
Noise has a great impact on people’s sleep. Even when people are sleeping, their hearing must be stimulated by the noise. Noise can cause excessive dreams, easy awakening, and decreased sleep quality. Sudden noise has a more prominent impact on sleep. Noise can interfere with people's conversationsTalk, work and study. Experiments show that when a person is disturbed by a sudden noise, he will lose 4 seconds of concentration. According to statistics, noise can reduce labor productivity by 10 to 50%. As noise increases, the error rate increases.
Low-frequency noise is one of the most important hazards in cities. It refers to the sound with a frequency below 500 Hz, that is, the irregular sound produced by vibrating 20 to 500 times in one second is called low-frequency noise. At the 1980 Danish International Conference, the sound between 1 and 100 Hz was defined as low frequency noise (Low Frequency Noise), and the center frequency of the 1/3 scale was 2 to 63 Hz. There are five main categories of low-frequency noise sources in residential areas in China: elevators, transformers, water pumps in high-rise buildings, central air conditioners and traffic noise. The direct impact of low-frequency noise on physiology is not as obvious as that of high-frequency noise, but it can cause long-term damage to human health.
