Not only affects hearing, vuvuzela sounds or noise, but it also affects many other parts of our body and can lead to serious consequences.
The vuvuzela has become a very popular means of propaganda. This is a small trumpet but it emits a loud sound, creating a lively and boisterous atmosphere. However, because of such loud sounds, vuvuzela in particular and loud noises, in general, can become a cause of many health problems.
Auditory Effects – May cause complete deafness
The sound is too loud to the ear, not to mention lasting for tens of minutes or more, the auditory effect is inevitable, typically tinnitus, hearing impairment, temporary hearing loss Time … Even when the sound is too loud, right out of the ear and lasts longer, it can lead to complete hearing loss.
A prime example is a vuvuzela. According to a Live Science page, a study by the University of Pretoria (South Africa) in 2010 showed that a vuvuzela has the potential to make up to 113dB of noise. Hear the World, meanwhile, warns that sounds above 100dB for more than 15 minutes can cause complete hearing loss.
Harm on the brain and central nervous system
Having to hear loud sounds or continuous noise for extended periods of time will irritate the central nervous system, leading to serious consequences. It causes the brain to be affected, causing you to experience symptoms such as headache, dizziness, fear, unreasonable anger …, which in the long term also affects brain function.
Adversely affects the cardiovascular system
The World Health Organization (WHO) has demonstrated that noise is associated with high blood pressure, particularly when long-term exposure to noise is around 67-70dB. A number of other studies also show that sounds above 50dB at night can cause a heart attack by stimulating the body to produce cortisol too much and continuously.
Vuvuzela sound – Stress, stress, insomnia
Noise causes insomnia, nervous tension, and mental breakdown. A day exposed to loud noise or loud sounds, especially prolonged time will make you feel extremely tired at the end of the day. Many studies also show that noise from 35 dB or more can cause sleep disturbance. If that noise occurs at night, it can cause abnormal wakeups, alter the cycles of sleep, disrupt sleep and lead to insomnia.
Your Stomach is also affected by noise
It sounds unrelated but in fact, noise also has a certain effect on the stomach. It disrupts the secretion process and contractility, increasing acid in the stomach, which in turn leads to stomach ulcers.
