Occupational Noise and Exposure | Health and Safety

Welcome to occupational noise exposure, overview 22 million workers are exposed to potentially damaging noise at work each year. Last year US business paid more than 1.5 million in penalties for not protecting workers from noise. While it’s impossible to put a number to the human toll of hearing loss, an estimated 242 million is spent annually on workers' compensation for hearing loss disability objectives. Today you will learn about occupational noise exposure and the risks associated with it. While on the job you will learn proper steps and procedures for hearing protection and what is required to protect yourself. You will see examples of proper hearing protection that you will use to help prevent occupational noise exposure.

What is the noise?

Noise and vibration are both fluctuations in the pressure of air which affect the human body vibrations that are detected by the human ear are classified as sound the term noise indicates unwanted sound. Noise is measured in units of sound pressure called decibels or dB. Exposure to high levels of noise can cause permanent hearing loss, neither surgery nor hearing aid can help correct this type of hearing loss. Short-term exposure to loud noise can also cause a temporary change in hearing. An example of this is tendinitis, while short-term exposure may go away with. Within minutes long-term exposure or repeated exposure to loud noise can lead to permanent effects you.

What can be done to reduce the hazard of noise?

Hearing protection devices such as earmuffs and plugs are considered an acceptable but less desirable option to control exposures to noise and are generally used during the time. It is necessary to implement engineering or administrative controls, when such controls are not feasible or when workers hearing tests indicate significant hearing damage. There are some hearing protection examples earmuffs foam insert earplug sand semi RL caps. OSHA standard toOccupational noise exposure 9-CFR-1910.95 coverage protection beats the effects of noise exposure and what should be provided when the sound levels exceed.
Octave band sound pressure levels may be converted to the equivalent a weighted sound level by plugging in on the graph and noting the elevated sound level corresponding to the point of the highest penetration in sound level contours. This section deals with employees when they are subjected to sounds exceeding those listed in the table on the right in this case feasible administrative or engineering controls should be utilized. If such controls failed to reduce sound levels, personal protective equipment should be provided. We use two new symbols within the sound levels, the employer shall administer a continuing effective hearing and conservation program, whenever an employee’s noise exposure is equal or exceeds an 8-hour TWA sound level of 85 dB measured on the ACL or given a dose of 50%. A piece of information indicates that any employee exposure not equal or exceed an 8-hour TWA of 85 dB, employers shall develop and implement a monitoring program. Employers shall make hearing protectors available to all employees exposed to an 8-hour TWA of 85 dB or greater, at no cost to the employees hearing protectors shall be replaced as necessary. The employer shall ensure that hearing protectors are worn when they are required.

Reminder!

Always wear proper PPE, life is worth listening to wear hearing protection.
