Insulation value at high frequencies (assumed sound insulation for sound with
LC-LA =-2dB)
Insulation value at medium frequencies (assumed sound insulation for sound
with LC-LA = +2 dB)
Insulation value at low frequencies (assumed sound insulation for sound with
LC-LA = +10 dB)
noise levels LC and is used to estimate the eff ective A-weighted sound level
