However, in the 1998 revised criteria for a recommended standard for occupational noise exposure, NIOSH researchers published risk estimates for hearing loss as a function of years of exposure and noise exposure level. Additionally, as part of the NIOSH Project SENSOR surveillance effort, a limited amount of data on other aspects of occupational hearing loss has also been gathered.
Of the 28,400 cases of occupational hearing loss recorded in 2004, the majority were from the manufacturing sector. Additionally, it should be noted that hearing loss may not be well documented in the construction sector because these workers are not required to be given hearing tests.
Hearing is a complex process involving the coordination of many different parts of the ear and nervous system. The outer ear consists of the auricle, the part of the ear that we can see, and includes the ear lobe and the external ear canal. Sound, which is carried through the air like a continuously moving wave, makes the eardrumvibrate.
The middle ear chamber is connected to the back of the nose by a small canal called the eustachian tube. A good example of how this mechanism works is to think of the popping sensation experienced during altitude changes such as while landing in an airplane or traveling at high altitudes.
The interior of the organ of hearing or cochlea is divided into three compartments by strands of tissue, as in a shell.
Fluid waves in the cochlea are changed into electrical impulses, which travel rapidly along the auditory or hearing nerve to the brain. The nerve pathways leading to the brain are enclosed in a small bony canal along the nerve responsible for balance, and the nerve that stimulates the movement of the facial muscles. The nerve hearing pathways divide as they reach the brain into an extremely complex intercommunication system.
Ultimately, nerve impulses are transmitted to a certain part of the brain behind the temple.
A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard-of-hearing.
An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve. Assistive listening devices (ALDs) include a large variety of devices designed to improve audibility in specific listening situations.

Bellman® Audio Maxi is a revolutionary fully digital Personal Communicator for difficult listening situations and helps to bring out speech in for example conversations, TV-watching or in the car. In certain cases neither a conventional hearing aid, nor a cochlear implant will be adequate to compensate for a specific hearing loss.
A Baha® consists of a titanium fixture and abutment (implant) that is placed in the mastoid bone behind the ear where it grows with the living bone. In general, people who have middle ear problems, or can hear with only one ear, are ideal candidates for a Baha®.

I have had students over the years who present like they are learning disabled,but the confusion or difficulties they have had clearly are due to their hearing loss.
Depending on the definition of exposure and impairment, NIOSH estimates that there are between 5 and 30 million workers in the U.S.
As shown in Table 1, the 1997 NIOSH analysis of those frequencies likely to be affected by noise (1, 2, 3, and 4 kHz; see highlighted column) demonstrates 1 in 4 workers (25%) will become hearing impaired at exposures to 90 dBA. However, in response to NIOSH recommendations, OSHA updated requirements in 2003 for recording occupational illness and injury. The number of recorded cases of hearing loss is likely to be an underestimate of work-related hearing loss cases for several reasons.
Finally, only the small number of workers in the mining sector who are covered by OSHA (rather than MSHA) would have qualifying hearing losses recorded on an OSHA Log 300. It contains three tiny bones, commonly called the hammer, anvil, and stirrup or stapes. These vibrations are then transmitted across the middle ear space by the tiny ear bones.
The popping sound is a result of pressure adjustments in the middle ear through the eustachian tube. The middle compartment contains the hearing hair cells that are bathed in special fluid. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier.
The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin (see figure). Instead, it can give a deaf person a useful representation of sounds in the environment and help him or her to understand speech. Some are designed to be used with hearing aids or cochlear implants (CIs), while others are designed to be used alone.

Maxi is developed especially for people, with our without a hearing instrument, who prefer a very easy-to-use device with large tactile controls and clear indications.
In cases where the middle ear is blocked or damaged, or where only one ear is functional, a Baha®, also known as a bone anchored hearing implant, is more effective. A Baha® is a bone conduction system that sends sound vibrations through the bone, directly to the inner ear.

She loves her newest friend, Dexter and created a story in hopes that children everywhere will learn to accept people with hearing loss and that kids with hearing loss will learn to accept themselves. By comparison, 1 in 12 workers (8%) are at risk of becoming hearing impaired at exposures to 85 dBA. A new regulation (29 CFR 1910.04 mandated that beginning in 2004 occupational hearing loss must be recorded on the OSHA Log 300. First, the OSHA criteria for a significant decrease in hearing from a workera€™s baseline hearing test, a standard threshold shift (STS), is much lower than the criteria needed to record changes on an OSHA Log 300. Nevertheless, the new requirement to record work-related hearing loss is a major improvement in our ability to monitor the incidence of occupational hearing loss. These special cells respond to the fluid waves produced by the movements of the tiny ear bones, the stapes.
The amplifier increases the power of the signals and then sends them to the ear through a speaker.
The in-the-canal (ITC) hearing aid is made to fit the size and shape of a person’s ear canal.

In November of 2005 the Bureau of Labor Statistics reported the results for this first year of recording occupational hearing loss (Figure 3). Long battery life time with up to 150 hours on one set of two normal AA batteries makes Maxi very portable!

There is little data regarding details associated with the number of workers with occupational hearing loss.
This is because there has been no requirement, and hence no mechanism, for recording such data. Labeling a student so they get the appropriate modifications and accommodations is important. What are your thoughts-keep them with just a hearing loss label or check for further special needs?Please comment below!
