White noise has a constant level when measured in frequency

White noise has a constant level when measured in frequency bands of constant width. Suppose a noise generator produces white noise over the octave bands 0.5,1,2,4,8 khz. Find the overall un weighted and a-weighted sound pressures if a sound pressure level of 90 dB is measured in the 4kHz octave band.
