We all know somebody affected by hearing loss, as nearly 1 in 5 Australians live with the condition. Quality of life can be significantly compromised for people with hearing loss and their families.
In contradiction to many people's understanding, hearing loss is rarely similar to the effect of turning down the volume on a stereo. If you feel that your hearing is not what it used to be, or are concerned that a loved one may be experiencing hearing loss - take a couple of minutes to do the online hearing tests provided here.
However, conductive loss accounts for only 10% of all hearing losses, and they range from mild to moderate in severity. When volume is sufficiently increased, clarity and understanding are usually intact for someone with a conductive hearing loss.
Hearing loss that originates in the inner ear is referred to as sensorineural hearing loss or - in laymen's terms, nerve deafness. While the overall volume of sound may be reduced, the clarity of sounds or voices is also affected.
An example of a mixed hearing loss may be someone with inner ear damage due to exposure to noise in their workplace over many years, who also currently has an infection that has led to a fluid build up in the middle ear.
While the ageing process is a major contributor to hearing loss, it is certainly not a condition reserved for the later stages of life.
Not surprisingly, given the impact of noise, males are considerably more likely to have hearing loss than women - including being twice as likely to have a moderate to severe hearing loss.
This graph shown here illustrates the time it takes to cause permanent damage to your hearing when you're exposed to different levels of sound.
Nerves have different sensitivities to deformation of the sensory hair cells within the cochlea.

A potentially permanent hearing loss that affects tens of millions of patients, especially those who are exposed daily to high noise levels. Frequent and long duration of exposure to loud sounds such as in industry, loud music, power tools, lawn mowers or firearms. Minimize exposure to loud sounds, such as reducing the volume when listening to television or music .
Also referred to as noise-induced hearing loss, sensorineural hearing loss is caused by damaged or destroyed hair cells in the inner ear that no longer transfer sound information to the brain. Sensorineural hearing loss can rarely be corrected medically or surgically, so hearing aids are the primary solution. Since sensorineural hearing loss is typically caused by exposure to loud noises, we highly recommend the use of ear protection if you find yourself around loud noises frequently. If you have any questions about sensorineural hearing loss or hearing loss in general, please contact one of our locations to speak with an audiologist.

There are many things that can cause damage to the auditory system, but the most common is noise damage.
Please visit the NIH’s Interactive sound ruler for examples of various types of sounds and their hazard levels. Musicians work in a high decibel environment in which hearing loss, tinnitus, hyper-sensitivity to sound and sound distortion can result.  Traditional earplugs are not a good choice for the professional musician, as they reduce sound by muffling low-to-mid-range frequencies, which change the frequency spectrum of what they are hearing. Hunting requires the ability to hear very soft sounds, while still having a need for protecting the ear from the peak noise levels of a gun blast.
When considering construction worker injuries many people think of examples of injuries caused by physical accidents from impacts such as a fall from a ladder or scaffolding. Construction workers are often exposed to loud noises which make them especially susceptible to the loss of hearing. Hazardous noise is defined as noise which exceeds 90bD (decibels) for an extended period of time.
Compared to a 9 percent risk factor for no noise exposure, and a 30 percent risk in manufacturing, construction, along with mining, remain the top two high-risk professions in industry.
The most common cause of hearing loss on a job site is intuitive: a lack of use of protective hearing equipment, which is required by law. First, the employer may not make them aware of the risks of working in an environment with hazardous noise and may not provide them with appropriate hearing protection. Lack of equipment to control noise can be a contributing factor to hearing loss as can failing to take breaks when working in an area containing hazardous noise.
Hearing loss typically occurs in areas where noise levels exceed 90bD – the established noise level that is deemed “hazardous” to workers’ hearing.
Hearing loss usually does not occur upon a single overexposure, although if the noise is loud enough, it may permanently or temporarily cause hearing loss. Workers who start young, and enjoy a lifetime of work in construction, may be at an increased risk for hearing loss, particularly if their exposure levels exceeded the maximum threshold during most workdays.


Sensorineural hearing loss is a type of hearing loss which occurs because of some type of damage to the ear. With repeated overexposure to hazardous noise, construction workers are most likely to be exposed to sensorineural hearing loss at some point during their lives.
Severe hearing loss occurs when some loud sounds are inaudible and communication is impossible or extremely difficult without a hearing aid.
Working in environments where construction is going on represent an inherent danger, because the noise level often exceeds the 100dB level. Tinnitus is just one symptom that results from the damage and destruction of those hair cells. In addition to hearing loss, workers may experience nervousness, a reduced ability to concentrate, a reduction in the quality of sleep, an inability to get to sleep in a timely or efficient manner, reduced productivity, and an increased risk of work-related accidents. Workers who lose their hearing are also more susceptible to feeling isolated and may have trouble communicating with co-workers. Passive protective devices or uniform-attenuating protectors use mechanical blocks or means to filter sounds to provide equal attenuation across the audible frequency range. The sounds heard with passive protection in place are more natural, clearer and less distorted than protection provided by low-quality alternative or conventional hearing protectors. Some workers may have the tendency to only wear hearing protection when they are currently working, but may not wear the protection when they have finished the job but are still on the construction site in an area where hazardous noise exists. Active hearing protection or “level dependent” hearing protectors block sound and also use electronic means to transmit low-level sounds through the hearing protector. Electronic devices also allow users control over the attenuation of hazardous noise, essentially allowing customization of hearing. Another benefit of these devices is that special FM or infrared (wireless) capabilities can be integrated into the device to provide one or two-way communication.
Again, for these devices to work, they must be properly fitted and worn during times when hazardous noise threatens the individual. Periodic replacement and maintenance is necessary with these types of ear protectors, which makes them a more expensive option.
Cochlear implants have been approved by the Food and Drug Administration for children and adults who are deaf or severely hard-of-hearing.
The implant itself consists of a microphone, which is capable of picking up sounds from the environment. Instead, they capture the sounds of the environment and convert them into electrical signals. If you feel that the risks that you’re being asked to take are unreasonable, you’ve suffered hearing damage on the job, or if  you’ve been injured in some other way on a construction site, don’t hesitate to speak with an attorney. The extent of the hearing loss varies too, from a mild to a severe hearing loss where loud safety signals may not be heard. The good news is that conductive hearing loss can often be medically treated, and in many cases, hearing can be completely restored. Other symptoms may also be present, such as ear pain, drainage from the ears, or a feeling of pressure or a blockage. In more than 95% of cases involving sensorineural hearing loss, hearing aids or cochlear implants are the recommended course of treatment.
People with sensorineural hearing loss will often hear people speaking, but can't always understand all the words, even when the volume is adequate. Studies have shown that exposure to noise is thought to be a contributing factor in around 37% of cases of the condition - and interestingly, around 50% of Australians with hearing loss are still of traditional working age (i.e.
This is illustrated through mandatory provision of ear protection on work sites and within factories. A sound that has high frequencies of vibration will excite receptor cells near the opening of the cochlea, while a sound mostly containing low frequencies will stimulate cells at the end of the cochlea. Hearing loss of this sort is often caused by prolonged exposure to very loud noise, though auditory pathways (or hair cells that transfer sound) in the brain are sometimes abnormal at birth, resulting in some level of hearing loss.
Correctly fitted hearing aids amplify tones based on an individual’s unique sound deficiencies. When you refer a friend or family member with a hearing loss you will, in many cases, be changing their quality of thier life.
We want to thank all of our patients and their families for their trust and kind referrals. Custom musicians earplugs are available that can protect the musician’s ears from loud sounds without distorting what they hear.
Loud, sudden noises (gunfire, industrial noises, woodworking, motorcycles, loud music, motorized lawn equipment, noisy hobbies and other noises louder than 90 db) are more damaging to hearing than regular and extended exposure to loud sounds over a period of time. However, there are many other types of injuries that occur in addition to those that occur from strictly physical accidents.
There is a 60 percent chance of construction workers losing their hearing if they are exposed to hazardous noise throughout their career. There may be one of two common reasons why construction workers do not use hearing equipment. When hearing protection does not prevent hazardous noise from reaching the ear, or fails to do so effectively, the worker may be unknowingly exposed to excessive noise. Finally, a lack of training about how to wear hearing protection can contribute to the risk of overexposure and hearing loss. Job sites where workers are exposed to, or must use or interact with, heavy machinery, jackhammers, sledgehammers, nail and bolt drivers, electrical saws, and constant noise from demolition pose the most serious risk.
Permanent hearing loss occurs over time when repeated overexposure is experienced by the worker. This typically occurs because of an obstruction like earwax or a tumor is blocking sound from getting to the ear.


Damage may occur to the inner ear or the nerves that are responsible for hearing (auditory nerves).
Mild hearing loss is usually associated with the inability to hear soft sounds or difficulty understanding speech in noisy environments. Workers who are continually exposed to loud noises benefit the most from this type of hearing protection. As workers get hearing protection without distortion or muffling, they feel less isolated on the job site.
Workers must wear their passive hearing protection until they are clear of hazardous noise areas. Anything that exceeds that level is automatically reduced, thus preserving the wearer’s hearing through limiting and preventing overexposure. These provide the best hearing protection in environments where hazardous noise occurs, but where communication is still important, even critical.
This allows workers to communicate with each other without risking overexposure to hazardous noise levels in situations where they are spaced apart and cannot effectively communicate by other means. There is no official cure for hearing loss, but there are some treatments which may improve hearing or augment it. As of December 2012, there have been roughly 324,000 individuals worldwide who have had the procedure and received implants. Instead, it gives deaf or hard-of-hearing individuals useful representations of sounds in the environment. The technology requires that the patients still have basic functional hearing and that the ear drum assembly, inner, middle, and outer ear are structurally intact. More commonly it is manifested as a difficulty with word understanding, particularly in the presence of background noise. This can lead to conversations being difficult to follow - particularly in noisy environments where competing background noise 'scrambles' speech and conversations. Nevertheless, every day millions of Australians are exposing themselves to noise levels that will surely lead to long-term damage to their hearing, including the use of personal stereo systems. Commonly, over time the high frequency hair cell receptors receive more movement by the incoming pressure waves of the fluid inside the cochlea - so are more prone to long term damage than the low frequency hair cell receptors, which are more protected further up the cochlea.
Typically, sensorineural hearing loss reduces the ability to hear faint sounds or causes speech to sound faint or muffled, which results in the need for sound amplification.
In most cases, total communication is greatly improved through the addition of hearing aids. There are also a variety of in ear monitors that will enhance the music experience whether you are a serious musician or just a music aficionado. Not only can they choose from custom or over-the-counter earplugs or earmuffs, they can also choose protection devices that provide amplification while reducing the sounds of gunfire down to a safe level.
Workers who reach the age of 50, and have been working in construction for at least several years prior, are the most likely to experience hearing loss. This is typically not associated with damage caused by overexposure to noise or sound on a construction site, but it must be ruled out by a physician. Moderate hearing loss occurs when workers are unable to hear soft and moderately loud sounds and have considerable difficulty understanding speech, especially background noises. If possible, the hearing protection device should be custom-fitted for the individual, and considerable time should be spent explaining the importance of always wearing hearing protection. Loud noises, even sudden loud noises, are reduced to comfortable levels, while low dB noises are not muted or attenuated. Because it’s electronic, it should be inspected prior to each use to make sure that the power is on, or that the device is properly charged and functioning normally.
While cochlear implants are an available technology, they are still relatively expensive and full hearing restoration is not guaranteed. For these individuals, they must relearn how to hear after the procedure and full hearing restoration is never guaranteed. A transmitter receives signals from the speech processor and then converts them into electrical impulses.
The labyrinth system of the ear must also be normal or at least not so abnormal that hearing becomes physically impossible. Not unsurprisingly, being able to follow conversations is the single biggest reason that people seek our help.
Approximately 36 million Americans have hearing loss and 33% is related to exposure to noise.
Hearing protectors not properly fitted to the wearer’s ears do not effectively prevent damaging noises from penetrating the ear canal. The result is that the worker can carry on a conversation with another co-worker without the need for special communication equipment and without removing the protective gear, risking overexposure. A second option is a hearing aid, which does not restore lost hearing, but rather amplifies sound, making hearing easier.
Patients must learn to associate the signal provided by an implant with sounds they remember. Finally, an electrode array collects and transmits the impulses from the stimulator to various regions of the auditory nerve.
