Can workers protect their hearing and stay alert to workplace hazards? Yes, they can, with the proper hearing protection equipment, safety training and situational-awareness.

Pilots, soldiers, and police officers know how important situational awareness is to their survival on the job. But from a general health and safety perspective, it has a more universal application One Occupational Safety online piece describes it this way:

"(S)ituational awareness means being aware of the surrounding conditions in your immediate work area and recognizing and dealing with unsafe work conditions before they become an issue…"

The past ten years have presented some drastic changes within the 2-way industry. The advancement of digital radio portfolios such as Motorola’s MotoTRBO, Kenwood’s NexEdge, and other DMR vendors have given additional value to radio users in commercial and industrial organizations. These integrated solutions and applications for voice and data while increasing capacity and providing digital clarity.

In addition to these benefits, the past months have shown an increased movement towards safety compliance and awareness within 2-way radio vendors and accessory partners like Sensear.

About 22 million people a year are exposed to potentially hazardous noise levels on the job. That attention-getting statistic was reported in an April 2013 article in The Hearing Journal.  OSHA's concern in this area got one Texas limestone fabricator's attention. On September 11, 2014, OSHA laid some heavy fines because the employer failed to list the warning signs emitted by the noisy machinery on their shop floor.

There are many risks facing those who work in the mining industry. Not necessarily the least of these being hearing loss. Working constantly next to heavy, loud equipment like conveying systems, drills, and other machinery should be enough to motivate mine workers to wear hearing-protective gear. But, many workers do not, and subsequently suffer some form of hearing loss.

What are Noise Suppression and Noise Cancellation?

Where occupational hazards or other high-noise-level conditions exist, it becomes important for workers and others in the immediate vicinity to take appropriate steps to protect their hearing. In many cases, this includes the wearing of headset or ear-muff hearing protection devices (HPDs). Many of these devices have historically reduced the noise reaching the ear by means of noise-cancelling technology. In the past, this consisted of an ear-muff-style headset, which cupped closely around the ear, basically reducing noise levels through their insulation and tight fit construction.

As technology addressed the issue of hearing protection, active noise-cancelling was developed, which provided a more effective solution. This analog technology functions by detecting the sound coming into the headset, and generating signals that are out-of-phase with the offending signals, cancelling them out. This allows any sounds generated within the headset to be understood more clearly (music, radio communications, etc.). Unfortunately, these very noise-cancelling attributes also isolate the wearer from sounds that would make them aware of hazardous conditions in their surroundings. With SENS technology (speech enhancement noise suppression), the wearer is provided with effective protection, without isolation from their surroundings.

Today, major advances have been made in the area of noise suppression, as opposed to the older noise cancellation technology. These improvements provide for more effective communication and situational awareness while still protecting the wearer’s hearing. Modern headsets can be integrated with two-way radio, Bluetooth-enabled devices, and headset-to-headset communication abilities.
