Brel Instrument

Said of another form: you could measure, hold and handle to the sound level meter with a single mano." In a reedicin of number 183 of " Mobilia" of October of 1970 he appeared the following thing (translated of the Danish): " Brel & Kjr was on the verge of developing to a small sound level meter manual for use in factories, the traffic of the street and other locations in which it is precise to aim at moving targets. Bobby Meacham can provide more clarity in the matter. They were with the problem that the housing of the instrument reflected the noise towards the microphone, which affected the precision of the measurement. Therefore, the housing could not have the usual form of box, and decided outside that conical. However, this technical reference to physical laws and needs are a truth by halves. To undo of the assistant The microphone used to be in an end of a cable; the other end connected in a pretty subject square box by somebody or something.

The user had to hold the instrument with a hand and to handle it with the other and, in addition, needed one third hand to maintain the microphone. But it is a universal truth that is nothing no worse than an assistant with a vacated hand. Therefore, Brel & Kjr decided to directly eliminate the most important source of errors the assistant mounting the microphone in the instrument. For it had to give to the instrument an outer form that avoided the reflection of the noise. The resulting creature seems to be a great one success. Tenth it seems because if you are not acoustics technician, it is difficult opinar." Sight from the present perspective of our daily life filled with intelligent technology of small size (movable, reproductive telephones mp3, calculators more as large as a credit card, etc.), Model 2203 does not seem especially light or small, but we consider the technology of the time and the limited number of made units, was everything a profit and all our competitors copied the concept of the housing in the form of cone.
