  • 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.
  • 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.
  • 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.
