Critical bandwidth at one kilohertz is about 150 hertz

Evidence

This is done in Fig. 6.6 where this ratio is plotted as a function of 2jmod, the overall spacing of the three components. The spacing iJ.j = 2jmod at which the decreasing part reaches o dB is a measure for the critical bandwidth, 150 Hz for the I-kHz case plotted in Fig. 6.6. — Professor Dr.-Ing.

Categorization

• QUESTION: One numerical value for critical bandwidth at 1 kHz under this phase-detection method; worth cross-checking against other methods and classic ERB estimates.
• XREF: Compares with the ~130 Hz critical bandwidth at 1 kHz often cited from Zwicker-style measures.
