Industrial

We frequently get calls to come and assess noise levels in industrial facilities. The concern is usually whether the employee’s exposure to noise is meeting OSHA requirements. So what are standard OSHA requirements for employee noise exposure? There are three main points to the OSHA noise exposure requirements. The exposure limit is based on a […]




Industrial plants are most often loud and dynamic work environments. Noise fields are complex with varying levels of noise produced by many different pieces of equipment, and employees spend varying amounts of time near the different noise sources. Sound levels are even impacted by the building, with taller spaces generally quieter than single story spaces, […]




Generally speaking, sound systems in industrial spaces are there to serve two purposes. One is to reproduce pages for people in the plant to hear. The second is to play background music for people to listen to. For years, it’s been about that simple. An amplifier, maybe a small mixer, and a few paging horns […]




Fundamentally, sound is “that which we hear”. What we hear at any given time can greatly influence us. We use sound to communicate, to express warning, fear, pleasure and excitement. Some sounds can relax us and help us fall asleep, while other sounds can distract us and make it more difficult to perform simple tasks. […]




Over the years as an acoustical consultant I’ve seen a lot of architectural firms locate rooftop air handling units over or near acoustically sensitive spaces; then they put up resistance to doing the necessary extensive noise controls that are needed for such a situation. The protest usually includes “but we’ve never had to do that […]




It seems like everyone is talking about decibels these days: “5 dB of this” and “3 dB of that.” As acoustical consultants, we hear people using these metrics and often wonder to ourselves, “Do they really know what a decibel is?” Occasionally, someone is brave enough to ask the more important question, “Just how much […]




OSHA, The Occupational Safety and Health Administration, has long had policies regulating noise in the workplace. Their “Hearing Conservation Program” is designed to protect workers from suffering hearing loss even if they are subject to loud noise exposures over their entire working lifetimes. But navigating the waters of OSHA’s 1910.95 Noise Exposure Standards document can […]




I am not about to compose a post vilifying the American industrial complex; I’m only expressing the attitude of many people that I come across who live near a noisy factory, processing plant, scrap yard, or other type of industrial facility.  Perhaps in some cases, criticism by nearby residents is justified, but usually it is […]
