Hearing Protection has changed a lot in the work place. As occupational health and safety issues have been increasing there is has been increasing statutory obligations for busines to provide health cover for their employees. There has also been an increasing need to consider the effects high noise volumes impact on the ears of those working in places such as construction and other industrial zones.
In line with this innovative ear muffs and ear plugs that provide hearing protection while assisting listening have been introduced on the market. In the past communication in high noise environments above 85dB(A) has been virtually impossible unless you are a genius at some sort of sign language. However clear communication has been made possible by these new ear muffs. However this is no longer the case.
The technology has been achieved by providing a complex series of algorithms (if you understand this you might be better than me) This revolutionary solution combines an array of tiny microphones seamlessly connected to a small processor discreetly fitted within the products. The processor acts to distinguish speech from background noises that a range or products can be produced that protects the ears of workers and site visitors in high noise environments.
The technology used in these ear muffs is the only technology that can effectively distinguish speech from background noise. According to the manufacturer who first introduced this technology this technology is revolutionary.
The technology uses post filtering techniques. This is accomplished in real time and is done through very low levels of power consumption. Binaural capability, which is the natural ability to decipher direction of any sound, is retained along with background noise characteristics but lowers noise to safe levels to allow the user to remain aware of what is going on around the place. The outcome of this is a high quality natural speech coming in to the ear muffs or earplugs. This can also be connected to Bluetooth, mobile phone or two way radio.
The advantages of these hearing protectors include providing speech enhancement and hearing protection across impact, continuous and intermittent noise conditions. The hearing protectors provide priority to speech while suppressing excessive surrounding noise factors. Therefore a person's speech can be heard in areas otherwise inaudible. This removes the need for aggravating boom microphones. It is probably the only technology that provides intelligible speech in the most difficult backgrounds.

The company which has produced the world's first electronic ear plug model last year (2008) has won the Medical and Healthcare category at the DuPont Innovation Awards. This is only one of many awards it has received for its innovative technology. These hearing protection ear muffs have won popularity over the last eighteen months throughout Australia, Europe and the US and is gradually being introduced in to Asia-Pacific rim of nations.
There are a number of other suppliers who are now promoting this product throughout the world. It is believed that as its reputation increases the hearing protection ear muffs will be a common sight in industrial work places and other places of high noise volume.
