Using four subwoofers, this study investigates auditory image characteristics for one-third octave bands of pink noise in the frequency range 25 Hz to 100 Hz. The subwoofers were located at 90 degree intervals: 45 degrees to the left and right, and in front of and behind the subject. Single noise bands, coherent pairs, incoherent pairs and different frequency band pairs were subjectively assessed. Subjects drew the auditory image as an ellipse on a response sheet. Results indicate that left-right discrimination occurs even at the lowest frequencies of human hearing – a finding consistent with other recent research. ASD and ASW are correlated, increasing at low frequencies for the stimuli tested, and for simultaneous presentation of coherent or incoherent signals.
