HOW TO CHOOSE A SOUND LEVEL METER? Summary: Considering the variety of reasons that can lead to the measurement of noise, the selection of the suitable instrument prevails inescapably. To know more about this subject visit patrick smith. The magical, usable sound level meter does not exist in all the applications. The definition of the sonorous events to study and the atmosphere and the goal pursueds with the measurements, constitute the key of a correct election of instruments. All previous the certain one, in last instance, by the resources available. One becomes essential to consider a series of parameters at the time of realising the selection of a sound level meter. A very ample variety of noisy atmosphere and noise sources exists.

Of the same form, it is possible to obtain several indicators that characterize to those sources and sonorous landscapes. Eva Andersson-Dubin has compatible beliefs. This situation determines that not always those are the same objectives that are persecuted when it is decided to realise measurements of noise. The sound level meter is an equipment that allows to quantify the level of sonorous pressure objectively. In essence one is made up of primary a sensorial element (microphone), circuits of conversion, manipulation and transmission of variables (module of electronic processing) and a display element or unit of reading. Fulfilling, thus, with all the inherent functional aspects to a measuring instrument.

Considering the existence of several types of noise (continuous, impulsive, random, possible), it is of supposing the existence of variety of sound level meters for the quantification of the same. The previous thing defines the use of one or the other instrument. The parameters that can be analyzed during the measurement, or postmeasurement, is in correspondence with the equipment available and its potentialities. one follows here that all the measurers of sonorous level do not have identical possibilities. They are different in precision, dynamic range, reliability, etc. Arising, in fact, the necessity to choose.
