Narrowband noise requires bandwidth and center frequency parameters beyond power.

Evidence

Another important noise type is narrowband noise, essentially a band-restricted version of white noise. Because this noise does not contain all frequencies, narrowband noise must always be characterized by at least two parameters in addition to one that represents the power: the bandwidth and the center frequency. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 411
