Non-normalized field tests generally produce ratings that are 3 to 5 dB higher than tests done in accordance with the accepted ASTM standards. In the revised code only the raw receiving levels are used to compute Eq. The State of California legislature modified the standard FSTC and FIIC procedures to make them less strict by dropping the room constant and area terms. If room volumes fall below these limits the field report must include a notation to that effect. Minimum room volumes are 2100 cu ft (60 cu m) at 100 Hz, 1400 cu ft (40 cu m) at 125 Hz, and 800 cu ft (25 cu m) at 160 Hz. Receiving rooms are required to meet minimum volume requirements such that there are at least 10 room modes at 125 Hz and the same modal spacing at 100 and 160 Hz. Test standards set minimum limits on the volume of the receiving space at each third-octave frequency. They apply only to the room in which they are measured and are not generally applicable to a type of construction. These are designated FIIC, and like the FSTC tests fall about five points below the laboratory test for the same construction. Calculation of an IIC Ratingįield tests of the IIC rating also may be carried out after a building has been constructed.
