The noise ratings shown on the nameplate of a product are those measured in an anechoic room per the relevant JIS standard that specifies measuring procedures including the distance between the noise source under test and the sound level meter To select types of ventilating fans observe the following three notes 1 The environment affects the noise level The nameplate values are those measured in an anechoic room Actual buildings have echoes from the walls floors and ceilings so that the noise level depends on the building materials used and how wide the room is Use appropriate echo coefficients to determine the actual noise level and available fan types 2 Vibration Motor driven fans a type of rotating machine inevitably produce vibration though our largest efforts to reduce such vibration have been made To minimize vibration propagation and resonance the product should be firmly mounted on the wall 3 Synthesis of sounds When using two or more ventilating fans in a room consider the synthesized effect of sounds W Other noise Echoes Depending on the type or material of the wall and ceilings of the room and in small room echoes occur e Vibration Vibrating objects produce vibrating sound by moving their surrounding air 20Hz or higher frequency sounds are audible Noise due to ducts resistance Higher static pressures acting on the fan will produce larger sounds DAIKIN gt HRV gt Heat Reclaim Ventilation 259 11 p
