The threshold of hearing is frequency-dependent and it has been shown that … WebFurther examination of the graph in Figure 2 reveals some interesting facts about human hearing. First, sounds below the 0-phon curve are not perceived by most people. So, for example, a 60 Hz sound at 40 dB is inaudible. The 0-phon curve represents the threshold of normal hearing. We can hear some sounds at intensity levels below 0 dB.

WebThe human ear can consciously discriminate amplitude differences of about 1dB, and experiments show subconscious awareness of amplitude differences under .2dB. Although a complete answer would probably have to account to the equal loudness contours - we may be able to tell a 1dB difference with 1kHz, but not so for 100Hz. Frequency
