The critical bandwidth at 1 kHz measures about 150 Hz via phase detectability.

Evidence

Sound of a given frequency can block our ability to hear softer sounds at nearby frequencies, but distant frequencies are not affected. The threshold for detecting the softer sound is raised by the presence of a louder sound within the same critical bandwidth. Even if the softer sound is audible, it will not seem as loud as it would if played alone. Similarly, two tones that fall within the same critical bandwidth will appear to be less loud together than two tones of the same total energy that fall outside each others’ critical bandwidths. — Eric J.
