Performance Data; Sound Performance Data - Trane HUV Installation Operation & Maintenance

Tables S1 and S2 reflect sound power ratings for the vertical and horizontal classroom unit ventilator. To cal-
culate the noise criteria (NC) for a unit, subtract the actual room effect from the sound power number in each
octave band. These numbers may be graphed on a NC chart. Note: Because room affects vary greatly, request
exact numbers per the specific job from the design engineer. By obtaining these exact numbers, the most ac-
curate results of the installed unit may be calculated.
Data obtained in the reverberant rooms conforming to ANSI S12.31 and ANSI S12.32
