3. Performance sound insulation
The sound insulation performance of our sound protection enclosure was
measured by an independent laboratory according to DIN en ISO 3744 .
Measurement method
•
Measurement of sound power of the calibrated (MP1)
•
Reference source via a ball surface with 12 microphones. Acoustic
data: Class 2 According to DIN en ISO 3744, as third spectrum and
octave spectrum.
•
Measurement of Sound Power (MP2) of the Solflex Sonasafe Sound
Insulation Housing Reference source in the housing via a ball surface
with 12 microphones.
•
Acoustic Data Class 2 according to DIN en ISO 3744, as a third
spectrum and octave spectrum.
•
The difference between the two measurements is the sound insulation
power of the noise-isolating housing.

* The measurement tolerance of +/-1.5 db (a) or tolerance width of 3 db (a)
according to DIN EN ISO 3744 would finalised not be used and we publish
excluding the minimum sound insulation performance data.
Measurement results
Both the HC sound insulating housing with air intake rear and with air intake
