Hearing loss from loud noise limits your ability to hear high frequencies, understand speech, and reduces your ability to communicate, which can lead to social isolation. Damage to your hearing can be prevented, but once permanent noise-induced hearing loss occurs, it cannot be cured or reversed.
It is generally recommended in Australia to have workplace noise levels kept below 85 dBA as an 8-hour time-weighted average. This range of hearing protections is available from Hip Pocket Work Wear (opposite Bunnings) Ioanthe Street South Grafton. According to the Alberta Occupational Health and Safety Codea€“Noise Regulations, employers must develop and implement a written noise management program. The first step in a hearing conservation (or noise management) program is to measure the noise levels that the workers are exposed to. The level and type of noise that workers are exposed to will determine what needs to be done to protect them. Measuring of the sound levels identifies the sources of noise and what workers are most likely to be exposed to noises exceeding the Occupational Exposure Limits in the Safety Code. Any area where noise levels exceed 85 dBA, appropriate hearing protection is required and workers exposed to these areas must have their hearing checked regularly. Hearing protection should be placed in an easily accessible, prominent location at all entry points where noise hazards exist. Placing information or reminder notices on safety boards (if available) can also increase compliance. Any visitors entering any noise hazard area should be informed of the available hearing protection and correctly wear it upon entrance. Stressing the importance of using appropriate hearing protection, as well as increased monitoring, helps to increase employee compliance with noise management protocols. Engineering Controls - According to many regulations, when noise exposures exceed mandated levels, engineering and administrative controls are to be the first line of defense in reducing exposures to acceptable levels. Administrative Controls - Most regulations state that when noise exposures exceed mandated levels, engineering and administrative controls are to be the first line of defense in reducing exposures to acceptable levels. Hearing loss can affect your quality of life by interfering with your ability to enjoy socializing with friends, playing with your children or grandchildren, or participating in other activities.

Hearing loss usually occurs gradually, so you may not realise it is happening until it is too late. For every 3 dB (decibels) above this level (meaning the noise has increased) it halves the exposure time, i.e.
If such controls are not feasible or practical, personal protective equipment (earplugs and earmuffs) should be implemented.
Administrative controls include such actions as giving noise-exposed workers breaks in quiet areas, or rotating employees into noisy jobs for short durations so that no single employee is overexposed.
Construction sites have many noisy operations and can be a significant source of noise exposure.
The key is to identify equipment that is producing excess noise in the work area and implement controls to keep personal full shift noise levels below 85 dBA. Engineering controls include such actions as installing acoustic enclosures, barriers, mufflers, dampers, vibration isolators, or acoustic treatment of walls and ceilings. If such controls are not feasible or practical, personal protective equipment (earplugs and earmuffs) should be implemented. Loud noise can also reduce work productivity and contribute to workplace accidents by making it difficult to hear warning signals. The noise levels that are produced when firearms are used can lead to permanent hearing loss. This makes it necessary to use hearing protection with good noise reduction rating.Firearm Sound LevelsIt is important to know how loud a firearm is to understand the need for hearing protection. However, if the sound of a rifle going off makes your ears ring, it indicates that you are prone to hearing damage. If the noise levels increase to 130 dB or higher, an individual can suffer from permanent hearing loss immediately. The devices designed to lower noise exposure should have the right Noise Reduction Rating (NRR) to protect your ears from damage.What is Noise Reduction Rating?Noise Reduction Rating refers to a measurement unit applied to determine hearing protection effectiveness. There are various devices that are designed to reduce sound exposure in various environments. Shooters need these hearing protection devices but they have to be tested and certified by OSHA and the American National Standards (ANSI).

A high NRR number on a hearing protector indicates that it has a greater capacity to reduce noise.How NRR Changes Noise ExposureIf you wear hearing protection when using a firearm, the level of noise you are exposed to is determined by the NRR rating on the device in use. It is important to understand that while NRR is measured in terms of decibels, the device you use to reduce exposure will not reduce sound levels by the exact decibels that are related with its NRR. To determine how much noise exposure is reduce, deduct 7 from the NRR on the device and divide the result by two. It is advisable to use hearing protection appropriately to enhance noise reduction.Hearing Protection OptionsIt definitely hurts when you shoot magnum revolvers or centerfire firearms without protection.
The good thing is that gunfire tends to be short but it can still have a significant impact on your hearing. There are various hearing protectors available to protect your from ear damage.Ear Plugs These are a simple option that can help you to reduce the amount of noise that you are exposed to when you use a firearm.
If you want something light to protect your ear, they are ideal.Earmuff Hearing Protection They look like headphones and most shooters prefer them because you do not have to place them inside your ear.
You can choose earmuffs with foam ear cushions or liquid filled ear cushions depending on how much you want to spend. One of the main advantages of these hearing protectors is that you can use them with earplugs when you are using indoor ranges.
This makes it difficult to have conversations or listen to your surroundings when you are shooting.Electronic Earmuffs These hearing protectors feature an in built audio amplifier.
There is a tiny microphone in both muffs and they are designed to pick up external sounds and amplify them before they are fed to a speaker.
Electronic earmuffs are an ideal choice especially when you are hunting because you can hear everything around you.ConclusionYou can continue to enjoy shooting without compromising the health of your ears.
