## masking_filterbandwidth.jpg

The image is a scientific graph titled "Figure 3.6." It illustrates estimates of auditory filter bandwidth from various experiments plotted as a function of center frequency in kilohertz (kHz). The x-axis represents the center frequency, ranging from 0.1 to 10 kHz, while the y-axis shows the equivalent rectangular bandwidth (ERB) in hertz (Hz).

The graph includes data points representing different studies:
- Open circles represent Moore, Peters & Glaberg's study (1990).
- Filled black circles indicate Shailer et al.'s work (1990).
- Open squares correspond to Dubno & Dirks' research (1989).
- Crosses mark Moore & Glabberg’s findings (1983).
- Asterisks denote Zhou's study (1995).
- Filled black circles with a dot in the center represent Glasberg & Moore's work (1998).

The solid line on the graph represents an equation suggested by Glasberg and Moore (1990). Two points are shown for a center frequency of 14 kHz, as filter bandwidths were estimated at two different noise spectrum levels: 40 dB and 50 dB. The ERB was greater at the higher level.

The source of this graph is attributed to "Moore 2007 'Cochlear Hearing Loss'."
