This training video will help keep your employees safe as well as meet the OSHA training standard.  To safeguard all workers from these hazards, OSHA has established two important benchmarks. — First, if the noise in a workplace reaches an average of 85 decibels over an 8-hour period, an employer must implement a "hearing conservation program". — Second, the program must ensure that employees are not exposed to average noise levels greater than 90 decibels over the course of a shift.  The employer is also required to provide employees with: — Appropriate hearing protection. — Hearing safety training. — Free medical tests to monitor their hearing. 3  To keep noise levels at or below the 90 dB limit, companies use a "system of controls".  Some of these are physical safety measures such as: — Installing quieter equipment. — Isolating sources of noise from surrounding work areas. — Putting up sound-absorbing barriers.  Administratively, work shifts can be adjusted to limit the amount of time employees spend in high-noise areas.  When measures like these cannot reduce workplace noise to a safe level, workers will need to wear hearing protection.  Several types of hearing protection are available. — Each has its own advantages, disadvantages and requirements for proper use and care. — They are all marked with a "Noise Reduction Rating" (NRR) that indicates how much noise reduction they can provide.  To determine how much noise reduction is required in a workspace, subtract OSHA's 90-decibel safety limit figure from the area's measured noise level. — For example, for a workplace that averages 105 decibels of noise over an 8 hour period, subtracting 90 dB leaves 15 decibels.  If hearing protection is uncomfortable or gets in your way, you might be tempted to take it off. — You should never remove your protection in a noise-hazard area. — Hearing protection has to fit right and it can't interfere with the work that you do.  Several types of ear protection are available, including: — Ear muffs. — Ear plugs. — Canal caps.  "Ear muffs" generally consist of two cushioned "cups" filled with sound-dampening material, mounted on a "headband".  "Cap mounted" ear muffs attach to safety helmets. — They're used in places where conditions are such that both the head and the ears need to be protected.  For best protection, the cups must make a secure seal against your head — Glasses, facial hair or other PPE such as a respirator can sometimes interfere with a good fit.  Muffs are popular because: — They're easy to use and can be worn with ear plugs if additional protection is needed. — They aren't easy to lose or misplace. — They don’t tend to irritate the ear or cause infections.  While ear muffs cover the outside of the ear to prevent hazardous noise from getting inside, "ear plugs" and "canal caps" block sound from inside the ear canal itself.  Ear plugs are an especially convenient type of ear protection. — They're small and lightweight. — They are more comfortable to wear in hot working conditions than ear muffs. — They don't interfere with other protective equipment such as respirators. — They are inexpensive (especially the disposable type).  But ear plugs also have disadvantages: — They can easily be lost. — They provide less protection against high noise levels than ear muffs. — Putting them in and getting them out can sometimes be difficult. — Some people find that they irritate their ear canals.  Another important element in an employer's hearing conservation program is conducting regular hearing tests for employees who work in high noise areas. — These tests are conducted by healthcare professionals and provided to employees at no cost.  The tests determine how loud sounds have to be for a person to hear them at various frequencies. — The results are plotted on an "audiogram", providing a visual representation of the employee's hearing. 7  The first test establishes a baseline of how well an employee can hear, before they start work in a high noise environment. — As further tests are conducted, usually on a yearly basis, those results will be compared to the baseline, to determine if any changes have occurred in the employee's hearing.  If the testing shows a 10 dB reduction in an employee's ability to hear sounds at frequencies of 2000, 3000 or 4000 hertz, the employer is required to notify the employee. — This type of change is called a "Standard Threshold Shift", or STS. — If one is detected, further testing may be necessary.  If the hearing loss is determined to be permanent and related to exposure to workplace noise, the employer will take whatever steps are necessary to prevent the employee's condition from getting worse.  Having these hearing tests regularly can help to catch hearing problems early... so they can be dealt with more effectively. — So make sure you don't "skip" yours if you're scheduled for one.
