What are the risks of noise?
Noise damage can lead to permanent hearing loss, and without hearing it is extremely difficult to perform most tasks in everyday life.
If the sound is too loud, the noise-sensitive hair cells in the inner ear and nerve cells in the auditory nerve can be damaged. How harmful noise is depends on how intense the sound is, how long it lasts and how sensitive the hearing cells are.
Noise damage is a gradual injury. It causes no pain, does not cause any visible physical damage and starts as a temporary condition and then becomes permanent. Unfortunately, this often leads to early signs being ignored. Help is usually first sought after 40% hearing loss.
Noise damage leads to serious lifelong disability and affects the ability to work, the ability to communicate and quality of life. This leads to a significant increase in the risk of accidents at the workplace, e.g. because warning signals are not heard.
Common symptoms include isolation, communication difficulties, difficulty in being in environments where many people are talking (restaurant visits), being unable to hear birds and crickets chirping, tinnitus, health problems such as high blood pressure, irritation, stress and disrupted sleep.
Noise damage is permanent but can be 100% prevented.
