ALWAYS ON ALERT Noise levels at construction sites require regular monitoring and complaints must be dealt with quickly and effectively. DUO features a highperformance alert system. If predefined limits are exceeded or the battery is low, you will receive an SMS notification, centrally managed by the 01dB WebMonitoring service. As an added security measure, an SMS message will also be sent if the unit moves by more than 10 metres. ALWAYS UP TO DATE Capturing noise level measurements at industrial sites is a complex task, due to factors such as multiple noise sources, variable operations on site, and the effect of weather conditions. With integrated GPS, DUO can perform localised and synchronised measurements to identify the influence of different noise sources at various times of the day. “IEC 61672 Class 1 certification (for both 0° and 90° reference directions) demonstrates the level of care taken by 01dB to ensure DUO’s metrological quality” EASY TO INSTALL Wind farms are often installed in areas that are difficult to access. As a result, installation and remote monitoring constraints need to be taken into consideration in the noise impact study. DUO’s all-in-one, all-weather design offers the perfect solution, with easy installation (no cables), a 60 hour battery life and an integrated 3G modem to retrieve data without having to leaving the office. DUO also provides the core metrology for RoBin, a system dedicated to measuring sound power levels from wind turbines in accordance with IEC61400-11. Designed and validated by expert acousticians, RoBin ensures optimal flexibility on site including wireless connectivity; only one operator required; and automated calculation and reporting. “À la carte” services 01dB WebMonitoring Based on a fixed monthly subscription, 01dB offers a range of WebMonitoring services, from stations rental including 3G subscription to cloud storage and a dedicated, customised website. These services are available to all customers who purchase DUO to support noise monitoring projects.
