Availability: In stock

Measure and record sound levels anywhere!

Check the decibels of any noise source at your workplace, in your neighborhood or at home. And with this instrument you can even record data so you have the data to prove it.


Test if a Noise Source in Your Neighborhood or at Work is Dangerously Loud

The ennoLogic eS528L is a professional sound level meter that provides reliable decibel readings over a range of 30 to 130 dBA with an accuracy of ±1.5dB. The large backlit display is easy to read from anywhere and in any environment. Use this instrument to measure and record noise levels in offices, factories, in your neighborhood or at home.

Use this Decibel Sound Level Meter to Get Convincing Data

You might want some solid data to convince your coworkers that they should wear ear protection at the worksite. Or fine tune your audio system at home. Or make sure your new aftermarket exhaust is operating below the maximum permissible noise level limits. The uses are endless, and you’ll soon find yourself walking around your home checking the sound level of everything.


  • THE ENNOLOGIC DECIBEL METER provides accurate sound level (decibels or loudness) readings from 30 to 130 dB with ±1.5 dB accuracy. It is the ideal tool to discover if something at your workplace or in your neighborhood is too loud, potentially causing hearing damage. Loudness is highly subjective and difficult to determine without proper equipment. Use this Type 2 decibel meter to get convincing data for any situation.
  • AVOID OR RESOLVE DISPUTES WITH YOUR NEIGHBORS: Monitor and record noise levels in your neighborhood and outdoor traffic in your area. Check how loud your car audio is. Make sure your aftermarket exhaust is below the noise ordinance limits. Check the decibel level of leaf blowers, weed eaters, lawn mowers, and tractors. Know the actual sound level in decibels before talking to your neighbors.
  • DETERMINE IF YOUR WORKPLACE IS SAFE: Do you need to prove to your coworkers that a noise source at your workplace is too loud and causes hearing damage? Monitor sound levels on a construction site? Now you can monitor and record sound levels of machines or equipment, or perform area noise monitoring anywhere. Unlike other meters, the ennoLogic eS528L can record noise levels for hours or days for later review and to provide supporting data.
  • VERY USEFUL AT HOME: Balance the outputs of your home theater speakers, not easily done by ear. Sound proof doors and windows. Measure how quietly your air conditioning runs, or sound levels of home appliances. Or take this meter to a store to compare the noise level of appliances or air conditioners before purchasing.

Units seams to work well software could do with being more flexible would be really nice to put notes onto the graph eg next to peters desk or next to printer Z ultimately it means importing onto another program and adding the details wanted
