ERB is the standard metric for auditory filter bandwidth
Evidence
Auditory filter bandwidths are commonly reported in terms of their equivalent rectangular bandwidth, or ERB. This value quantifies the bandwidth in terms of an equivalent filter that is rectangular in shape. Other measurements of bandwidth can also be used, such as one defined using the 3-dB down points, which correspond to measures from the filter skirts defined by the frequency at which the attenuation is 3 dB. However, the ERB is much more commonly adopted in psychoacoustic literature. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 501
