Noise-induced hearing loss most often results in permanent damage which cannot be treated medically. Wear hearing protection (foam or silicone plugs or muffs) when around loud equipment such as a lawn mower, power saw or leaf blower. Check with your employer regarding federal noise regulations if you are exposed to loud noise at work.
Avoid medications that can be dangerous to your hearing a€“ ask a physician about possible ototoxic effects. Ongoing Exposure to Noise on the JobLong-term exposure to continuous loud noise can cause lasting hearing loss. Michael Rothschild, MD, director, pediatric otolaryngology, Mount Sinai Medical Center, New York.
National Institute on Deafness and Other Communication Disorders, National Institutes of Health. Prevention tips as well as a chart outlining decibel levels of everyday sounds are included. Additionally, our hearing ability gets worse at the age of from 30 to 40 and can be led to hearing loss at the age of 80. Such noises from workplace, music, concert, MP3, vehicles, and so on can increase the risk of being hearing-impaired. To be specific, some certain antibiotics and cancer drugs as well as some other drugs such as aspirin, NSAIDs, and acetaminophen lead to some side effects that are the main reason for hearing loss.
It is intended for general informational purposes only and does not address individual circumstances. No matter how well a person may be trained, distractions, weariness, pressure to restore power, or over- confidence can cause an electrical worker to bypass safety procedures, work unprotected, drop a tool or make contact between energized conductors.
Hearing loss can grow as the newborn is premature or from such other causes as trauma during birth leading to the infant getting inadequate oxygen.
It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health.
Continued excessive exposure often results in decreased sensitivity to other types of sound, eventually impacting speech understanding. Never ignore professional medical advice in seeking treatment because of something you have read on the WebMD Site.
If equipment cannot be deenergized, electrical workers must be “qualified”, trained, wear appropriate personal protective equipment (PPE), and follow all applicable OSHA and NFPA standards.It is important to remember that proper selection and application of overcurrent protective devices (OCPD) will also substantially reduce the hazards.

The results of the Electrical Hazard Analysis will determine the work practices, protection boundaries, personal protective equipment, and other procedures required to protect employees from Arc-Flash or contact with energized conductors. Injury or Pressure ChangesSevere head trauma can dislocate middle-ear bones or cause nerve damage, causing permanent hearing loss.
Sudden changes in pressure -- from flying or scuba diving -- can lead to damage to the eardrum, middle ear, or inner ear and hearing loss.
Chronic DiseaseCertain chronic diseases that are not directly related to the ear can cause hearing loss.
Autoimmune diseases, such as rheumatoid arthritis, also can be linked to some forms of hearing loss. How You Hear -- Anatomy of the EarSound waves enter the outer ear and travel through the ear canal. This causes the eardrum and tiny bones, called the hammer and anvil, in the middle ear to vibrate. Then vibrations travel to the fluid in the cochlea where microscopic hairs send nerve signals to the brain so sound is understood. Tumors and GrowthsNoncancerous growths, including osteomas, exostoses, and benign polyps, can block the ear canal, causing hearing loss. Acoustic neuroma (an inner ear tumor shown here), grows on the hearing and balance nerve in the inner ear.
While commissioning large electrical systems, I came across few breakers that did not fit the buss bar correctly.
Today, the co-ordination studies are more focused on limiting danger to workers than to limit the nuance tripping. That follows a recent US court decision that sided with an injured worker who by his own omissions caused a short in an electrical panel and was injured. The average decibel level at a rock show is 110, loud enough to cause permanent damage after just 15 minutes. Hearing damage can occur with extended exposure of any noise over 85 decibels.
An electrical engineering company was found guilty by setting up the protection devices in order to limit the nuance tripping rather than to protect a worker working on the electrical panel.
The arc flash labels are the proper way to establish the use of personal protective equipment (PPE).
I am an experienced person and I can assess the possible and obvious fault levels just by looking around: checking transformer sizes and upstream breaker settings.
Headphones and EarbudsCan others hear the music and lyrics you’re listening to through earphones?

Unfortunately, there are many old electrical installations that do not have arc flash labels. Ask the users that have installed RMU and other arc-proof switchgears, and control the temperature and the quality of the air in switchgears’s rooms if they have problems with arc flash. Think you have an earwax blockage? Don't try removing the wax with a cotton-tipped swab or by inserting anything else into your ear canal.
Ear infections can cause the middle ear to fill with fluid and cause hearing loss that usually clears when the infection and fluid are gone. Not my way.Anyway, I disagree that arc-flash incidents in MV switchgears are not very often, at least not in my 15y expirience.
Diseases known to affect hearing in children include chickenpox, encephalitis, influenza, measles, meningitis, and mumps. In the matter of fact, in that time I heard of 4-5 incidents with 6-7 dead engineers in total. And MV switchgears are average old about 7-12 years.Caution is a must, as well as a complete understanding of what creates arc-flash and how to protect yourself. All major manufacturers pay a huge attention to safety when working in substation with energized or de-energized equipment.By the way, I do a dosen of other things other than LV busbar design, but it would be a kind of stupid to write essays of it, wouldn’t it? Though congenital hearing loss often runs in families, it can occur with maternal diabetes or an infection when pregnant. Hearing loss can also develop if a newborn is premature or from other causes such as trauma during birth resulting in the infant not getting enough oxygen.
Hope, that some gear switch designs are suicidal and out dated but are still in use is not helping matters.
Usually, age-related hearing loss is caused by the progressive loss of inner-ear hair cells. All designs should as a matter of safety incorporate all fixtures that will ensure the safety of personnel.
