A noise-induced hearing loss can be caused from a one-time exposure to a very loud sound or from exposure to loud sounds that last a long period of time.When people think of noise induced hearing loss they often think of adults who work in environments where they are exposed to loud noise such as landscapers, construction workers, members of the military or possibly factory workers. These numbers may be due to the high number of children today who are now using headphones to listen to music, movies and video games. The symptoms of noise-induced hearing loss are the same as they are for any other hearing loss. The best way to prevent noise-induced hearing loss is to understand risks and that the damage to your ears is irreversible. For individuals who already have hearing loss, it is highly recommended that they use hearing protection when they are exposed to loud noise.As an audiologist, I often counsel my patients that they need to protect the hearing they currently have and hopefully prevent further hearing loss.
You only get one set of ears that have to last your entire life … so protect your hearing now. 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. Hearing is one of our most crucial senses, which allows us to communicate, to learn and to enjoy things like music and conversation. Every year, millions of people suffer from hearing disorders, which range from partially impaired hearing to complete loss of hearing ability. Loud noise can also lead to physical and psychological stress, increase heart beat rate, reduce productivity, interfere with communication and concentration, and contribute to workplace accidents and injuries by making it difficult to hear warning signals. The structure of the ear can be broadly divided into three main parts: the outer ear or pinna, the middle ear and the inner ear. When sound waves enter the outer ear, the vibrations cause the ear drum to oscillate and are transmitted to the middle and inner ear. Noise is measured in a unit called “decibel”, named after the scientist Alexander Graham Bell. Newer machines which operate with less noise should be used in industries and construction sites. Work which generates more noise should be carried out in covered zones, so as to reduce noise transmission. Noise barriers can be placed at the perimeters of noise source, such as construction sites. Trees should be planted in every place, around the noise source as they are the natural absorbers of sound.
Rooms which are more occupied should be constructed on the side of lesser noise prone area.
Workers in industries should wear safety earplugs, and should not work for more than prescribed time limit. Hearing protection devices like earplugs, headphones and mufflers can be worn to protect oneself from noise. Used by churches all over the world to help teach worship, the Experiencing Worship study can help your worship team too. Of the roughly 40 million Americans suffering from hearing loss, 10 million can be attributed to noise-induced hearing loss (NIHL).
A bulldozer that is idling (note that this is idling, not actively bulldozing) is loud enough at 85 dB that it can cause permanent damage after only 1 work day (8 hours).
When listening to a personal music system with stock earphones at a maximum volume, the sound generated can reach a level of over 100 dB, loud enough to begin causing permanent damage after just 15 minutes per day!
A clap of thunder from a nearby storm (120 dB) or a gunshot (140-190 dB, depending on weapon), can both cause immediate damage. Because the damage from noise exposure is usually gradual, a person might not notice or might ignore signs of hearing loss until more pronounced symptoms of permanent hearing loss become evident.

However, many people do not realize that they are exposing their ears to a huge amount of potentially damaging noise on a daily basis, even though they are not in noisy regions like industrial area or construction sites. Majority of the people facing this problem belong to the labour class, and also those people residing around regions where noise level are always above the safe designated level. Noise – induced hearing loss limits your ability to hear high frequency sounds, understand speech, and can impair our ability to communicate.

The outer structure of the ear is responsible, in part, for helping us to place the original location of a sound.
In the middle ear three small bones (hammer, anvil, stirrup) amplify and transmit the vibrations generated by the sound to the inner ear. Researchers  have stated that the noise level of more than 85 dB can be harmful for the hearing mechanism of the ear. The use of such techniques should aim to reduce the hazardous exposure at least to the point where the risk to hearing is minimized. Also, the cover zones should be designed in such a way that the sound does not echoes of reverberates, which might otherwise affect the workers. NIHL 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. It is estimated that as many as 30 million Americans are exposed to potentially harmful sounds at work. Hearing loss is gradual and over time people notice they have more difficulty.Very often people will report tinnitus or ringing in the ear as their first symptom.
Short term exposure to loud noise can also cause a temporary change in hearing or a buzzing sound in your ears.
It also helps to funnel and focus sound waves on their way to the middle ear and auditory canal.
In the inner ear, the snail-like structure called cochlea, which is filled with fluid, is lined with cells with very fine, microscopic hairs which move with the vibrations and convert the sound waves into nerve impulses which are sent to the brain for interpretation via the auditory nerve.

This is to be expected in the music world, but many churches operate at equally dangerous levels. Your ears are very delicate and prolonged exposure to sound pressure levels above 85dBA will cause damage to your hearing.

Even outside of work, many people participate in recreational activities that can produce harmful noise (musical concerts, use of power tools, etc.). Other common symptoms are difficulty hearing in background noise and having to ask for repetition. Continued excessive exposure often results in decreased sensitivity to other types of sound, eventually impacting speech understanding.
These short-term problems might persist for few minutes or hours after leaving the noisy area. The middle ear contains the auditory canal, which spreads upto the eardrum, or tympanic membrane.
If you have ever been to a party or to a concert where loud music was played, you may have experienced Temporary Threshold Shift (TTS). These cells respond to mechanical sound vibrations by sending an electrical signal to the auditory nerve. Sixty million Americans own firearms, and many people do not use appropriate hearing protection devices.
Attached to the other side of the eardrum, are three tiny bones or ossicles, the malleus, incus and stapes (or hammer, anvil and stirrup) which then attach to a fluid filled structure called the cochlea of the inner ear at a point called the oval window.
This temporary loss of hearing can become permanent if exposure is done on a regular basis. One way to tell if you've been exposed to excessive sound pressure levels is that you tend to hear a ringing in your ears.
Different groups of hair cells are responsible for different frequencies (rate of vibrations). Warranty and policies are in the manuals: We suggest you read them to help you avoid costly and potentially fatal mistakes. It is in the cochlea that the vibrations transmitted from the eardrum through the tiny bones are converted into electrical impulses sent along the auditory nerve to the brain. Ringing in your ears, hissing, clicking or buzzing sounds all represent the effects of tinnitus, which is often a side effect of noise-induced hearing loss. We're pretty easy to get along with but we claim no responsibility for misuse, abuse, or criminal intent of our products or the info on this site. The inner ear, which is surrounded by bone, also contains semicircular canals, whose function is to maintain balance of sounds. But if they're damaged, the ears will still record ringing or buzzing, even when there's no sound. How does long-term exposure to excessively loud music cause hearing loss?
If the sound is very quiet, it will not cause damage even if you listen to it for a very long time; however, exposure to some common sounds can cause permanent damage. Basically, hearing loss occurs when the tiny hair cells in the inner ear are blasted away from repeated exposure to loud music.
With extended exposure, noises that reach a decibel level of 85 can cause permanent damage to the hair cells in the inner ear, leading to hearing loss. Our ears contain microscopic hairs as a fringe on the ends of auditory cells in the inner ear.

When healthy, these hairs move in response to the pressure of sounds that vibrate the eardrum. The electrical signals excite nerve cells in each of the some 30,000 fibers that spiral away from the cochlea, a snail-shaped and fluid-filled structure in the inner ear. This spiral of fiber fuses together to form the auditory nerve and carries stimulation from the ear to the brain, where sound is perceived. Continued or repeated exposure to loud music can damage the tiny hairs, leaving them twisted, bent, fused, and no longer able to respond properly to sonic vibrations. Where there are no healthy hairs, erect and swaying to each sound that travels to the ear, there will be no stimulus to the brain from that particular nerve, and perhaps nothing more to be heard. The ear's ability to hear sound is degraded even when only a relatively small number of hairs are damaged. There has been some research into microscopic hair cell regeneration in the ear, but unfortunately, the damage to the hair cells and the resulting loss of hearing appear to be permanent.
Think of what music would sound like if you couldn't hear anything above 10KHz: just like with a crummy old transistor radio or listening to music over a telephone (no cymbals or high pitched instruments, voices sounding deadened).
The high frequencies are lost first, so you may have difficulty hearing high-pitched voices.
Loss of high-frequency hearing makes many words sound alike, especially those containing the high-frequency sounds S or soft C, F, SH, CH or H. Words like "hill," "fill" and "sill" may sound exactly the same. Experimental evidence Researchers at the University of Florida tested the hearing of some middle and high-school students.
The investigators found that about 17 percent of the children had some degree of hearing loss. Most of the hearing loss was in higher pitches, which are usually the first ranges of sound to be lost after hearing damage.
The investigators believe that exposure to excessive noise results in a serious hearing impairment at an early age. Significant hearing losses were detected in a group of students who had a history of frequent attendance to pop music entertainment. A ‘guinea pig' showed hearing impairment in his right ear after listening to high-intensity rock music for 88 hours over a two month span. The left ear, protected by a plug during most of the music, demonstrated no cytological changes. The damage to the right ear was permanent. Why We Like It Loud It turns out that loud sounds directly affect our autonomic nervous system (also called involuntary - it controls the body functions that you hope never stop, like breathing and digestion), in a way similar to many stimulant drugs. This is the rush you get from loud music - it's real and it's beyond your conscious control. Because humans can perceive such a wide spectrum of acoustic energy, the units for measuring sound intensities are compressed using a logarithmic scale (based on the powers of 10) on which the sound intensity multiplies by ten every 10 decibel (dB) increase.
For example, the sound of a rock concert, approximately 120 dB, would have 1,000 times the intensity of a motorcycle (90 dB). The amount of noise and the length of exposure determine hearing loss; one can experience hearing loss or damage if there is a one-time exposure to a loud noise, repeated or long exposure to noise, or extended exposure to moderate noise. In 1970, the Occupational Safety and Health Administration (OSHA) developed a scale indicating the length of time a person could listen to a given dB sound level before experiencing hearing loss or damage. Sound Pressure Levels, which exceed these parameters, will cause ear fatigue, loss of concentration and potential hearing damage.
Similarly, operating your system at too low of level will also cause people to strain to hear the spoken word, resulting in ear and brain fatigue.
Purchase a simple sound level meter from Radio Shack and monitor your stage and house levels so that you maintain a balance. Most environmental noises include a wide band of frequencies and, by convention, are measured through the "A" filter in the sound-level meter and thus are designated in dB(A) units.
Proper adjustments of your system and room acoustics also play an important part in maintaining moderate SPL while maximizing intelligibility. These measurements should include the noise generated by the air conditioner, local traffic, etc. Typically, if the church noise levels are under control, good listening levels are generally in the low 60dB range. In some churches, the room noise is so low, that a PA system is not needed for speech or a good listening level of 55 to 60dB is OK, (but this is so rare.) If you have to always drive your sound system higher than 68dB, chances are you have a noise problem that needed to be address.
This allows many older people with minor hearing losses to hear better without driving the sound system harder and offending others with average hearing abilities. If these people continue to complain, then they will need a personal hearing-impaired system of some kind.
