Building Acoustics
-
Measurements to evaluate and improve Building Acoustics are typically made to analyze and design noise control from room to room, or from outside to inside. Noise sources such as music systems, televisions, appliances, traffic, aircraft, and manufacturing are all around us. The field of Building Acoustics evaluates and designs the materials and methods to insulate and isolate us all from these sound sources when we are at work, rest, or enjoying leisure time. The resulting data is useful for evaluating compliance with building codes and for proposing countermeasures for areas of concern. These measurements often involve creating and measuring an artificial sound source, and then measuring the resulting noise in receiver locations.

Sound Level Calibrator
521
-
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.
