3M Occupational Health and Environmental Safety  introduces the Sound Detector SD-200, a new line of compact and lightweight sound level meters designed for accurate measurement of workplace noise levels.   

Sound Detector SD-200 sound level meters feature an intuitive design that makes it easy for users to measure sound levels at the workplace and determine the degree of hearing protection that may be required for workers.  

The advanced integration feature computes the average sound pressure level (SPL) over a period of time, allowing for more accurate assessment of intermittent sound levels.   

Features and benefits of 3M Sound Detector SD-200: 

  • Integrating/ averaging function computes average sound pressure level for accurate measurement of intermittent sound levels
  • User-selectable LED alert screen provides quick visual reference of sound levels
  • Compact and lightweight design accommodates one-hand operation
  • Rechargeable battery facilitates less ongoing maintenance and lowers total cost of ownership

According to Peter Knott, Senior Occupational Hygienist at 3M Australia, the SD-200 sound level meters are entry-level sound detection tools designed for ease of use by those who need to perform sound level measurements as part of their job function.  

An advanced functionality in the SD-200 provides steady readings in environments where noise levels tend to vary, such as in manufacturing facilities and machine shops.  

He adds that the integrating feature, which computes the average sound pressure level over a period of time, is a more representative assessment of noise levels than using SPL alone.
