The technical training provided by Metroacústica may be carried out in the premises of the contracting company or in the place where the company indicates.

​

Metroacústica offers training in electroacoustic calibrations with scope according to guideline document DOQ-CGCRE-052: Guidance for calibration of acoustic measurement devices, for Brazilian calibration laboratories.

​

In trainings the topics of international technical standards listed below are discussed.

- Frequency generated
- Harmonic or Total Distortion

​

Measurement Microphone (IEC 61094-6: 2004)

- Sensitivity

​

Bandpass Filter (IEC 60225: 1966 and IEC 61260: 1995)
- Frequency response
- Relative Attenuation

​

In the training it will be presented standards requirements and calculations to perform conformity assessment of the equipment, in addition to the theory and practice of how the calibrations are actually performed.

The trainings will be carried out at the premisses of the contracting company or at the place where the company indicates.

The workload depends on the number and modules that will be contracted, which can be 6 or 7 hours a day.

​

At the beginning of the first day of training, a two-hour introductory module will be given where general topics related to conformity assessment, ISO / IEC 17025 standard, and the basic physical concepts on which calibrations are based will be addressed.

​

In each module, concepts for the estimation of the expanded uncertainty of measurement will be discussed.

The necessary requirements for the preparation of the calibration certificate that will be issued in each module will be presented.

​

Audio or video recordings of training will not be allowed.

​

The contracting company shall:
A) Provide location with adequate environmental conditions;
B) Provide whiteboard or flip-art, pens and eraser;
C) It is desirable that the projector or television is available for slide show;
D) It is desirable that the contracting company have necessary equipment and accessories to carry out the calibrations, such as signal generators and multimeters, for example.
E) To bear the costs of air and land transportation, besides lodging for the instructor in the city where the training will be carried out.
