As one of the world's leading developers, manufacturers, and marketers of hearing protection and communications products, E•A•R/Aearo Technologies, now part of 3M, provides leading-edge support to our customers and to the public at large, in the areas of noise and hearing conservation (often called hearing loss prevention) and hearing protection. One of the foremost examples is the widely acclaimed and often-quoted EARLog series of technical monographs that are available on this web site, the first of which appeared in print over 30 years ago. Other examples are our Audio Demonstration series that was one of the first audio products in the safety industry to make use of streaming audio on the web, the often-referenced Noise Navigator™ sound level database, and our new single-product training audios available for download or streaming on YouTube
