| The Science of Speech Enhancement in High Noise Environments |
Through considerable advances in the technology of hearing protective devices, which includes ear plugs, ear muffs, active noise canceling headsets, electronic tactical muffs, and other related products, protecting the hearing of the public in the workplace, around the home and in hobby situations has reached a respectably high level of accomplishment.
There remains one related problem: how to effectively communicate with others in the presence of dangerously loud noise? With most ear plugs, the high frequencies are clipped so badly that much of the voice quality is lost and thereby much of the information the voice is trying to convey. The same applies with ear muffs. The natural tendency when you cannot understand what is being said is to remove the hearing protective device, exposing yourself to hearing damage.
One approach to this pervasive problem has been to develop "natural sound" plugs and muffs, which includes the venerable ER-20 hi fidelity ear plugs and the Bilsom Clarity family of earmuffs. The problem with these devices is that they give the user a little better sound quality, but at the expense of protection from the ambient noise. In short, they work very well in moderate noise situations, up to 95 dB or so, but beyond that level, they do not provide sufficient protection.
Enter a new class of product: Speech Enhancement Devices or SEDs. We are excited to offer this genuinely new kind of hearing protective device now being produced by an Australian company, Sensear. Their trademarked SENS(R) technology adapts to each new environment within a few minutes, and is then able to pick out the sounds of a human voice from the background noises, then differentially amplify the voice while suppressing the background noise. This process lets the user clearly hear the voice of a person speaking, while providing protection from the ambient noise in which the conversation is taking place. Elvex, an American company has also recently entered the market with their own SEDs, the Level Dependent Com 655 and the DeTune Communications Earmuffs. These take a different approach to enhancing face to face communications in loud environments, and though not as sophisticated as the Sensear line of products, these are value priced and a great improvement over traditional ear muffs and plugs.
Speech Enhancement Devices, or SEDs are at the cutting edge of the high noise communications problem and to us, they look like the future.
