NIHL (Noise-Induced Hearing Loss) can be caused by a one-time exposure to loud sound as well as by repeated exposure to sounds at various loudness levels over an extended period of time. Scientists believe that, depending upon the type of sound, the pure force of its vibrations at high decibel levels can cause hearing loss.
Wear earplugs or other hearing protective devices when involved in a loud activity (special earplugs and earmuffs are available at hardware and sporting goods stores). If you suspect hearing loss, have a medical examination by an otolaryngologist (a physician who specializes in diseases of the ears, nose, throat, head, and neck) and a hearing test by an audiologist (a health professional trained to measure and help individuals deal with hearing loss. Hearing loss is something that we normally associate with aging, but many people who have impaired hearing are quite young. Detecting loss of hearing in a child can be quite difficult, especially if the child is very young. School-aged children can be a little easier when it comes to finding problems with hearing.
Detecting hearing loss in children can be difficult and complex, so you want to be sure that you go with an audiologist who is experienced in working with children. Every day, we experience sound in our environment, such as the sounds from television and radio, household appliances, and traffic.
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. The bones in the middle ear couple the sound vibrations from the air to fluid vibrations in the cochlea of the inner ear, which is shaped like a snail and filled with fluid. Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane. As the hair cells move up and down, microscopic hair-like projections (known as stereocilia) that perch on top of the hair cells bump against an overlying structure and bend. The auditory nerve carries this electrical signal to the brain, which translates it into a sound that we recognize and understand. While listening to music can be soothing to the nerves, exposure to loud music can have detrimental effects on hearing. With the advent iPods and music players, exposure to loud music has become very common and is especially preferred by teenagers. The loudness of normal conversation is at 60 decibels and the sounds between 60 and 80 decibels are loud noises. Extremely loud sounds affect the ears by damaging the hair cells of the cochlea in the inner ear.


Noise induced hearing loss can occur due to sudden one time exposure to a very loud sound or by continuous exposure to extreme decibels for a longer duration.
Decibel levels begin at zero, which is near total silence and the weakest sound our ears can hear. Recent studies also show that exposure to sounds at harmful decibel levels triggers the formation of molecules inside the ear that damage hair cells. All individuals should understand the hazards of noise and how to practice good hearing health in everyday life.
In fact, it is becoming more and more common for people to experience aging-like loss of hearing even in their twenties. However, there are some things that you can try at home to see whether or not you ought to take your child to an audiologist for a formal hearing test. For one thing, children are likely to be subjected to a hearing test upon entering school in the first place, which can be helpful. Once you detect the problem, though, you can start figuring out how to fix it, making your child’s life easier sooner. Hearing depends on a series of events that change sound waves in the air into electrical signals. An elastic partition runs from the beginning to the end of the cochlea, splitting it into an upper and lower part.
So, if your children are fond of loud music, here is something you need to know and help them maintain their hobby as well as their health. Loudness beyond 85 decibels can affect hearing and exposure to such noises for a long time can even cause permanent hearing loss. In case of temporary exposure to the sound, the cochlea can recover however repeated and continuous listening to very loud sounds can cause permanent damage. Noisy recreational activities, especially listening to music players set at loud volumes can damage the ears.

Noise-induced hearing loss is caused by damage to the delicate hair cells of your inner ear.
These destructive molecules play an important role in hearing loss in children and adults who listen to loud noise for too long.
One of the best ways to detect loss of hearing in an infant is to try to surprise the baby with startling, loud noises. But sounds can be harmful when they are too loud, even for a brief time, or when they are both loud and long-lasting.


Even if you can’t tell that you are damaging your hearing, you could have trouble hearing in the future, such as not being able to understand other people when they talk, especially on the phone or in a noisy room.
Our auditory nerve then carries these signals to the brain through a complex series of steps. This partition is called the basilar membrane because it serves as the base, or ground floor, on which key hearing structures sit.
While, the use of personal music systems is still studied, it is accepted that exposure to loud noise or music to extreme decibels can be dangerous. Once the hair cells are destroyed by exposure to harmful sounds, they cannot grow back, resulting in permanent hearing loss. Sure, some kids do tend to ignore their parents and caregivers when they can get away with it, but real loss of hearing should look different than a child who is choosing to ignore you. Most of the time in very young school-aged children, this is less because of a lack of interest and more because they can’t hear or see properly. These sounds can damage sensitive structures in the inner ear and cause noise-induced hearing loss (NIHL). Regardless of how it might affect you, one thing is certain: noise-induced hearing loss is something you can prevent. Come experience top-quality care you or your loved one deserve, with our caring Doctors that are committed to every person who walks through our doors. Check out the NIDCD for detailed information regarding the mechanisms of noise-induced hearing loss. Sometimes, irreversible hearing loss is caused by trauma or exposure to overly loud noises, and other times, loss of hearing can be temporary and can be caused by a blockage in the ears, which is quite common with children because of the way their inner ear anatomy is developing. Again, one good indicator would be a child who isn’t startled by loud, surprising noises. When your child is constantly getting bad reports from school, a hearing test should be one of the first things you try as a solution.
The sound of an ambulance siren at 120 decibels is about 1 trillion times more intense than the weakest sound our ears can hear. Also, if you have to repeatedly call your child to get his attention on a regular basis, or if your child talks very loudly to others, this could indicate hearing problems.
