Industrial & Manufacturing Soundproofing

Industrial noise is one of the labels we use to help us start the process of solving your noise problems. While it is a term used in the industry, industrial noise is a label we use in our process and we may define industrial noise differently than others in the industry. The development of an effective solution starts by first identifying the noise that is offensive, then determining the noise transmission path(s) and measuring the acoustic characteristics of the noise. The noise transmission path is simply the identification of the source of the noise and determining how it arrives at your ear.

Types of Industrial Noise

Here are some of the types of industrial noise you may encounter:

  • Airborne noise: passes through openings, apertures and other structural gaps
  • Ambient noise:background noise that can naturally occur
  • Flanking noise: The ability of sound to find the path of least resistance, passing around heavy, insulated areas into the adjacent rooms. When blocking sound, it is more like water than light – if there are any holes, the water will continue to flow until it has passed through the most easily.
  • Impact noise: The sound produced by the collision of two solid objects. Typical sources are footsteps, dropped objects, etc. on an interior surface (wall, floor, ceiling) of a building.
  • Impulsive noise: A) Either a single sound pressure peak (with either a rise time less than 200 milliseconds or total duration less than 200 milliseconds) or multiple sound pressure peaks (with either rise time less than 200 milliseconds or total duration less than 200 milliseconds) spaced at least by 200 millisecond pauses, B) A sharp sound pressure peak occurring in a short interval of time.
  • Masking noise: A noise that is intense enough to render inaudible or unintelligible another sound that is also present.
  • Pink noise:Noise with constant energy per octave band width
  • Random noise: An oscillation whose instantaneous magnitude is not specified for any given instant of time. It can be described statistically by probability distribution functions giving the traction of the total time that the magnitude of the noise lies within a specified range.
  • Structural borne noise: created by impact or by vibration
  • White noise: Noise with energy is uniform over wide range of frequencies, being analogous in spectrum characteristics to white light

Common Applications

  • Government facilities
  • Manufacturing facilities
  • Warehousing facilities
  • Power Plants

Compliance

Between OSHA and specific location regulations, it's important to be proactive in testing and undesrstanding the laws around noise control. If you are a business owner it is important to understand the noise ordinances that your community has in place! Different communities define industrial noise differently and you need to understand your local ordinances and laws to understand your responsibilities and rights when it comes to noise where you live and work. We can help you test and analyze to ensure you are OSHA compliant.
