Noise-induced hearing loss

introduction hearing loss occurs in two different forms, natural and noise induced hearing loss. natural hearing loss can occur from a range of medical issues, most natural causes can be cured with a range of drugs and therapies- unlike noise induced hearing loss (NIHL), where the damage is permanent and cannot be reversed. NIHL is majorly caused after long term exposure to noise as low as 75dB which has been known to cause hearing loss in many vulnerable individuals - including those who have prolonged

Noise induced hearing loss is a common and irreversible occupational hazard that affects a large number of individuals in a variety of professions (Fligor, 2011). In particular, firefighters are routinely exposed to loud sounds through sirens, air horns, alarms, and tools as well as hazardous chemicals that can have an ototoxic effect on the auditory system (Kardous & Afanuh, 2013). Due the excessive noise levels most firefighters are exposed to, firefighters view noise exposure and hearing loss

Hearing is very important in our everyday lives. It helps us to learn and socialize. Without hearing we are unable to communicate effectively. Sound can be harmful to the ears when it is too loud. When the inner ear is damaged, noise induced hearing loss can occur. “Noise induced hearing loss is a permanent hearing impairment resulting from prolonged exposure to high levels of noise” (Noise Induced Hearing Loss). Symptoms of NIHL happen gradually. It is important that one catches on to the symptoms

exploration of Noise-Induced Hearing Loss, Presbycusis, and Their Interactions. Robert B. Ellis HESP 636 Spring 2014. Peripheral hearing loss, in addition to other types of hearing loss, is very common among the elderly. For those who develop permanent, peripheral hearing loss in older age, there are two main etiologies. Exposure to severe acoustic trauma can cause hearing loss at any age. However, a life-time exposure of lower level environmental noise can also lead to hearing loss due to noise

impulsive Noise from the Gun Introduction Noise is one of the most widespread causes of hearing loss, and the most likely causes of occupational illnesses in the United States (Leigh 728). Acute or prolonged exposure to high-level, impulsive noise is an ongoing problem for the military and defense forces all over the world (Sliwinska-Kowalska and Adrian Davis 274). One shot from a big caliber firearm, perceived at a close range, may permanently or temporarily damage an individual hearing in an instant

Noise can be defined as unwanted sound1. Sounds which we deem as unwanted or unnecessary are noise. Our environment is beset by noise, which is pervasive, intrusive and ubiquitous as well as unhealthy. The effects of noise, a pollutant and its effects on health have been neglected despite being aware of the ability to precisely measure or calculate the exposure from the peak levels2. The effects of noise pollution were first recognized in the occupational settings. In our environment, there are different

The ability to hear is one of life’s great luxuries. Though it is possible to live with hearing loss, I cannot deny the impact hearing and sound has on my daily activities. From listening to my professors, to the numerous interactions I have on my cell phone, sound permeates all facets of my life. Not only is sound critical to my daily activities, it can impact an organization on the economic scale. For most of my life I worked for and with various manufacturing companies. During this time I

with the prevention of hearing loss among earbud users. Doctors have suggested following what is known as the 60/60 rule when using earbuds. The 60/60 rule is a guideline discussing an easy way to prevent further damage when using earbuds. This rule is a limitation that recommends not using earbuds for more than 60 minutes a day at 60% of the device’s max volume. Susan James and Kathryn Nathanson discuss how this rule allows the ears to have a rest from a direct source of noise (par. 18). Although this

Introduction Tinnitus is an ongoing ear noise affected by the build-up of wax or medicine that is dangerous in the ear structures. It also caused by the inner ear cell damage. Once these hairs split in the inner ear, they leak random electrical impulses to the brain, resulting in tinnitus (Brinson, 2006). These are tiny soft hair in the inner ear that moves about due to the pressure of sound waves. The hairs activate ear cells to release electrical signal over the auditory nerve to the brain. Then

What do you think of when you see the word “Hearing Loss”? Honestly, before doing research on this subject, the first thing that came to mind when I see this word is “Deaf”. Being ignorant to the fact that these are two completely different conditions. Surprisingly, I found that most people often confuse these words as well. There are several major causes of hearing loss and with in this writing we will discuss a few of them. Lack of knowledge is considered a cause because if everyone were more aware
