Compliance and Restrictions



A Popular Science “Best of What’s New” in 2011, Noise Indicator NI-100 is designed to alert users to hazardous noise levels. It clips to clothing and uses a LED light to offer real-time noise detection, signaling when hearing protection may be required.Innovative and durable noise detection, the NI-100 noise indicator alerts you when noises in an area reach potentially hazardous levels. The noise indicator’s small size and lightweight design make it ideal for workers in a variety of industries. With a rechargeable battery that operates for up to 200 hours between charges, it’s an economical investment in your hearing conservation program. The NI-100 can be used as an effective training tool within a Hearing Conservation Program (consult OSHA Standard 1910.95) to help ensure workers know when and where to wear hearing protection. Safety and health professionals can also use it as a mapping tool to determine where noise studies are necessary. In a variable noise environment, the 3M noise indicator can help train workers as to when noise levels become potentially hazardous and hearing protection may be required.

• Red Flashing LED indicates noise levels are above 85 dBA and hearing protection may be required.
• Green Flashing LED indicates noise levels are below 85 dBA and hearing protection may not be necessary.

*The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. 3M is Leading the Advancement of Hearing Conservation(TM). 3M(TM) Noise Indicator NI-100 is not Intrinsically Safe.
