4. 01 Noise Measurement Before Implementation presmetal.com.tr
Noise levels are measured with sound analyzer with
designated spacing around machines/devices.
Noise maps of areas are modelled from analyze
results of measurements.

5. 01 Noise Measurement Before Implementation presmetal.com.tr
Critical noise points are determined with
acoustic camera.
Critical points are used in acoustical
design stage.

6. 02 Acoustic Design presmetal.com.tr
Special designed acoustic materials for
specified noise spectrum are used
according to noise map for indicated
area.
Different special designed acoustic
materials are used on critical points,
which are determined with acoustic
camera. Complete sound isolation is
achieved with this way.

13. 07 Noise Measurement After Implementation presmetal.com.tr
Noise spectrum analysis are made after
application to approve reduction of
designated sound level.
Acoustic camera is used to find
imperfection of assembly operation.
After that step, application is successfully
done.
