* Values measured at 10 m for horizontal units in free field, directivity 2, in line with the coil. Tolerance ±3dB. ** Only the sound power level is characteristic of the unit. These values are obtained in compliance with the ISO 3744 standard. The difference between the sound power level and pressure level varies according to the site. To determine the unit's sound pressure level, recalculate it using the sound power level of the unit and the site conditions (you may need to consult an acoustical engineer). As the sound emitted by the unit is not uniform in all directions, for a point 10 m away in line with the fans, the recalculated pressure value must be increased by approximately 4 dB.
