The NRR: What's In a Number?

When OSHA promulgated its Hearing Conservation Amendment for general industry in the early 1980s, it incorporated the Environmental Protection Agency's noise reduction rating (NRR) system for assessing hearing protector performance. The NRR is a laboratory-derived estimate of the attenuation (sound reduction) that is to be expected from a hearing protector. Shortly after the Hearing Conservation Amendment went into effect, however, it became evident that the actual amount of attenuation achieved in the workplace often fell short of the laboratory-predicted NRR.

Oil and Gas: Health Concerns in Flowback Operations

Although physical safety hazards for oil and gas extraction operations are well known, there is very little published research regarding the types and magnitude of health risks linked to hazardous chemicals. Of recent concern are chemical exposures associated with flowback operations (storing and processing fluids involved in hydraulic fracturing).

Hearing Conservation for Mining Operations

According to the National Institute for Occupational Safety and Health (NIOSH), one out of every four mine workers has a severe hearing problem. Hearing loss can interfere with a miner's ability to communicate with family, friends, and co-workers. Hearing loss, particularly in a noisy environment, can also present a safety hazard when workers are unable to hear moving machinery and warnings.

Does Noise Increase the Risk of Accidents?

Loud noise is one of the most common and pervasive hazards in industry today. The risk of hearing loss due to excessive noise is well known and has long been studied. But other risks from noise have not been so clear. Is excess noise also to blame for accidents in the workplace? Are all workers at higher risk, or perhaps just those individuals who are hard of hearing?

Are Smartphone Sound Apps Really Accurate?

Have you ever wondered about the accuracy of all those smart phone applications now available for measuring noise? A group of NIOSH research engineers wondered, too. They reviewed nearly 200 iOS and Android-based apps currently offered in the marketplace.

Making Noise About Noise Pollution

Researchers at the University of Michigan and the Network for Public Health Law would like to change public policy when it comes to noise pollution. In an article published recently in Environmental Health Perspectives, the authors argue that noise in everyday life not only poses a threat to hearing, but is also associated with general health problems such as sleep disturbance, stress, hypertension, heart disease, and even injuries.

Special Considerations for Workers with Hearing Loss

How many times have you seen an employee break the seal of an earplug or earmuff because he can't communicate in the workplace? Individuals who are hard of hearing are often the worst offenders. Not only are these workers at risk of exposing themselves to hazardous noise, but communication typically isn't even improved. So what can we do to help?

Dual Hearing Protection: The Good, the Bad, & the Complicated

Although most noise exposures encountered in industry today can be adequately addressed with a well-fitted earplug or earmuff, some exposures exceed the capabilities of traditional hearing protectors. When intensely loud noise cannot be controlled at the source, special hearing protection measures may be required. In these cases, it may be necessary for workers to wear both earplugs and earmuffs at the same time, often referred to as "dual hearing protection" or "double hearing protection."

Firearms and Hearing Protection

As hunting season gets underway, it's a good time to talk about protecting your hearing during this popular, but loud, recreational activity. Research shows gunfire to be one of the leading causes of noise-induced hearing loss and tinnitus (ringing in the ears).

OSHA Proposes New Standards for Silica Dust

On August 23, the U.S. Occupational Safety and Health Administration (OSHA) announced a proposed rule to lower worker exposure to crystalline silica. "This proposal is expected to prevent thousands of deaths from silicosis-an incurable and progressive disease-as well as lung cancer, other respiratory diseases and kidney disease," said Dr. David Michaels, OSHA director.

Resources for the Oil & Gas Industry

The use of hydraulic fracturing (or "fracking") has increased significantly in the U.S. over the past several years due to improvements in drilling technologies and renewed interest in domestic energy resources. Because large amounts of silica sand are utilized in fracturing operations, the oil and gas industry is in turn dealing with heightened health and safety concerns for their workers. Matt Morrill, CavCom's Business Development Manager, has observed that environments with high noise and respirable silica exposure combine to create a unique challenge: "Now that NIOSH is recommending full face respirators, workers are having difficulty communicating via their current 2-way radios."

Custom-Made for Comfort and Success

In previous issues of SoundBytes, we have focused on some of the most common challenges to a successful hearing protection program. No matter how good the noise reduction rating, employees won't wear hearing protectors if they're not comfortable, convenient, compatible with other personal protective equipment, and allow good communication in the workplace. Now we would like to share one of the best solutions we've found to overcoming many of the objections you'll encounter: Custom hearing protectors.

Know Your Hearing Protection with Individual Fit Testing

Scientific studies have repeatedly shown what many of our customers have suspected for a long time...employees in the workplace rarely receive the amount of hearing protection predicted by the number on the box, the Noise Reduction Rating or NRR. The NRR can vastly overestimate, and sometimes even underestimate, the amount of protection an individual worker receives day to day.

Speech Communication in Noise

Noise remains one of the most prevalent hazards in industry today. And noise creates challenges in the workplace well beyond its most basic threat to hearing health. As demands on worker productivity become more complex, the need for efficient and effective communication is essential. Comprehending speech in the presence of loud background noise can be challenging at best, and at times nearly impossible. This month we review some of the basic principles affecting a worker's ability to understand spoken messages in a noisy work environment.

Comfort is the Key to Success

With the summer months approaching, it's a good time to think about tackling one of the chief complaints you'll hear about earmuffs, radio headsets, and personal protective equipment in general...all that gear can be hot, heavy, and downright uncomfortable. "It would be a mistake to choose a hearing protector or communication device based solely on Noise Reduction Rating (NRR)," explains Matt Morrill, Regional Sales Manager for CavCom, Inc. "In my experience, it doesn't matter how good the technology, if it's not comfortable, the worker isn't going to wear it."
