Note • White noise can be selected for masking of pure tones. The white noise signal is calibrated for pure tone effect-
ive masking, i.e. the white noise sound pressure level varies with the pure tone frequency. If you wish to obtain a cer-
tain white noise level measured in dB SPL, you should use Conversion Table 2 to determine the appropriate
attenuator setting. See AURICAL Aud ► 20
