Testing (and calibration) laboratories, to be good, must provide consistent accurate and precise measurements of the test objects based on their well-defined procedures. Lab accreditation is one way to assure the engineers, scientists, and technician

Often, but not always, acoustical insulation is used in place of thermal insulation, and vice versa. Often also, both are used for the same purpose. But the thermal and acoustical properties of a material are different and often not related. Hence a

Measuring microphones come with frequency response curves based on pure tone excitation in well-defined sound fields. Hence microphones have a distinct frequency response curve only for well-defined conditions. These conditions may, in fact, not be m
