Here you will find Noise Dosimeters (also known as Noise Level Meters or Noise Indicators) and Sound Pressure Level (SPL) Meters. These handy devices allow you to test exactly how loud your environment is, so you can determine for yourself whether the sound levels around you are safe or whether hearing protection is necessary to protect your ears from hearing damage. Noise dosimeters are most often used in industrial applications, but you can also use a noise level meter to test out any other noisy environment, such as your home workshop, the subway, football games or other sporting events, or any other loud location. Knowledge is power! The better you understand just how loud your auditory environment is, the more effectively you can choose the most appropriate hearing protection for all your favorite noisy activities.
3M Noise Indicator NI-100 automatically alerts a user when hearing protection is needed. The NI-100 clips to clothing and alerts the user to unsafe noise levels with a bright red flashing LED light that signals when hearing protection should be used. The NI-100 is designed for employee training and facility noise level mapping.
Etymotic Research Wearable and Programmable Personal Noise Dosimeter Model ER-200DW7 with Data Logging is an important tool for accurately determining the cumulative noise dose experienced by an individual over time, and then documenting the measurements.
