MEASUREMENT OF SOUND

Laboratory has the certificated (by TÜV NORD in 2015 year) acoustic chamber for noise measuring, where the measurements of the noise coused by different devices in the frequency range from 31,5 Hz to 10000 Hz can be performed.

Specialists of the laboratory can perform measurements of the sound from different devices: machines, domestic equipment. Max dimensions of the sound source should not exceed 4x4x4 m.

Measurements of noise are performed according to standards:

EN ISO 3744:2011. Acoustics – Determination of sound power levels and sound energy levels of noise sources using sound pressure – Engineering methods for an essentially free field over a reflecting plane.

EN 13141-7:2011. Measurement of noise emitted by the air handling units at the residential premises.

EN 1886:2008. Testing of the acoustic suppression of air preparation units.
