Noise Guard is a simple and cost-effective solution for environmental noise monitoring. The system is based on the Brüel & Kjær type 2250/2255 sound level meter, and enables continuous periodic measurements of basic sound parameters alongside the calculation of environmental noise indicators.
A new stand-alone solution for continuous or periodic environmental noise monitoring. In addition to noise data, weather data (wind speed and direction, temperature, air humidity and air pressure) is also recorded at the same time. With a future proof design, we intend to support the capture of other environmental data, such as cloud cover and air pollution in future updates.
Noise Guard is intended for:
- the measurement and calculation of environmental noise for reporting purposes or the calibration of noise maps
- stand-alone noise monitoring with the option of air quality monitoring with the addition of a weather station
- noise monitoring of construction sites to ensure compliance with regulations
- the monitoring of special events and providing warnings of exceeded noise levels
System characteristics:
- simple user interface
- detection of exceeded limit values
- periodic sampling of sound pressure levels
- compatible with Vaisala and Calypso weather stations
- notifications in case of exceeded limit values
- notifications in case of lost internet connection
- measurements and calculations of environmental noise indicators, in accordance with the ISO 1996 standard
- automatically calculates values at intervals of 1, 3, 5, 15, 30, 60, 120, 180, 240 and 1440 minutes
- up to 5 days of autonomy (applies to portable system or in the case of power failure)
- audio recording in case of exceeded limit values
Free software and technical support
When renting measuring equipment, we offer free software rental and provide free technical support 24/7/365.
Advantage when buying borrowed equipment
With prior agreement, you can purchase the borrowed measuring equipment with favourable terms.
Calibration of measuring equipment
All measuring equipment is thoroughly checked according to technical specifications before rental. Regardless, we can calibrate the equipment before acceptance and issue a corresponding certificate of accredited or traceable calibration. Calibration represents an additional cost.
User training
For an additional fee, we can set up the measuring equipment at the measurement site and carry out the necessary user training.
Rental conditions
A limited quantity and selection of measuring equipment and accessories is available for rental. The minimum rental period is three days. All prices listed next to the individual products are represented as a “per day” price, unless otherwise stated. A day is considered a working day, unless a holiday, Saturday or Sunday is intentionally chosen for the rental period. Microphones, accelerometers and other auxiliary equipment can only be rented together with the corresponding measuring equipment, unless otherwise agreed. A rental agreement must be signed before renting. The equipment must be returned to the agreed address no later than three days after the end of the agreed rental period.
