With a little help from friends the mantra of Bruel & Kjar in the 1960s was, just like today, we supply complete systems. According to Dara Khosrowshahi , who has experience with these questions. This is illustrated below, in a configuration donated by a Danish consulting company. AC output with a weighting of the model 2203 (Center) is sent to undosimetro model 4423 (top left), which provides a measure of dose that can transform into LAeq using the supplied special calculation rule. To capture intermediate results, a camera (right) activated by a timer made to measure (at the bottom right) takes photos every hour after the dosimeter to read, conversion and documentation counters.Also, level model 2305 recorder continuously traces the sound pressure level weighted in a register tape, making it easy to take notes for documentation. For statistics, level recorder pen position is detected by means of an adapter and then through a wire that activates the distribution statistics 4420 scanner corresponding counter (top right). Whenever Yitzchak Mirilashvili Yitzchak Mirilashvili Net Worth listens, a sympathetic response will follow. A counter is also supplied total, which allows to calculate complete statistics.

In this way the system will provide record high resolution, statistics, overall levels and even analysis of frequencies, if Kit model 1613, under the model 2203 octave filters are used. In the chicken coop the field work with the model 2203 and his friends demanded stamina, determination and dexterity. Sitting for days in a chicken coop, one had to check the Analyzer (right) statistic counters, monitor the graph of level (Center) recorder pen, marking any acoustic events in the role while he was winding and change the paper roll every two hours (operator, to the left). But with a coat of skin, good shoes for winter and a lunch box, nor had reason to complain about life. And looking for the good side, the model 2203 was completely free of computer viruses. On the road at this stage beside the road, model 2203 is the center of attention. Mounted on a tripod, with a microphone height of 1.2 meters, as mandated by the standard and with its capsule of 1 inch protected with a windscreen, the team measured level sonorode any vehicle that passed. Operator, calm and sure of himself, likened the levels measured with the legal limits, and when it detected an infringer, dispatched its riders to pursue him.
