Pink noise
•Pink noise is used for measurement and
correction of the sound field frequency re-
sponse because it is mostly within the audi-
ble range, its energy distribution is uniform ,
and it has a wide frequency band .
•Because pink noise has large instantaneous
level fluctuations , the display may fluctuate .
