Preventing Hearing Loss with Engineered Nozzles

My latest hearing test shows that I have had some hearing loss. Some would say that it could be contributed to 43 years of marriage. Others would say it was too many rock concerts. Its more likely from my exposure to loud machinery.

Every year, approximately 30 million people in the United States are  exposed to hazardous noise in the workplace. Noise-related hearing loss has been listed as one of the most prevalent occupational health concerns in the United States for more than 25 years. Thousands of workers every year suffer from preventable hearing loss due to high workplace noise levels. Since 2004, the Bureau of Labor Statistics has reported that nearly 125,000 workers have suffered significant, permanent hearing loss. In 2009 alone, BLS reported more than 21,000 hearing loss cases.

Exposure to high levels of noise can cause permanent hearing loss. Neither surgery nor a hearing aid can help correct this type of hearing loss. Short term exposure to loud noise can also cause a temporary change in hearing (your ears may feel stuffed up) or a ringing in your ears (tinnitus). These short-term problems may go away within a few minutes or hours after leaving the noisy area. However, repeated exposures to loud noise can lead to permanent tinnitus and/or hearing loss.

In previous posts I talked about the compressed air savings EXAIR’s engineered nozzles produced. But, they not only save air, they also provide a significant noise reduction. An open 1/4″ copper tube will exceed 100 dBA.  EXAIR engineered nozzles will operate at a quiet 71 dBA.Capture

I did an application for an automotive plant with transfer machines milling and drilling engine blocks. The noise was intense; hearing protection was required the moment you walked into the facility.  We retrofitted their entire plant blow offs with super nozzles and air knives. The sound levels of the environment were reduced so much, that hearing protection was no longer required.

A month after the nozzles were installed, I got a call from the corporate facilities manager. He asked me what is was I did in that plant because he was able to take a 100 horsepower air compressor offline; sound reduction AND air savings!

This is just one story of many where EXAIR has been able to conserve compressed air and provide a safer working environment.
