ACOUSTIC MEASUREMENTS

Laboratory has the certificated (by TUV NORD in 2015 year) acoustic chamber for noise measuring, where the measurements of the noise caused 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:

LST 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.

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

LST EN 1886:2008. Testing acoustic insulation of casing.

LST EN ISO 7235:2010. Acoustics. Laboratory measurement procedures for ducted silencers and air-terminal units. Insertion loss, flow noise and total pressure loss.
