The Detection Thresholds of Resonances at Low Frequencies

New experimental data on the detection thresholds of low-frequency resonances and antiresonances are presented. Using an adaptive procedure known as the up-down transformed response (UDTR) rule, the 70.7% detection thresholds were measured for a single added resonance (peak and notch) for different Q values and center frequencies. The signals included pink noise and pulses auditioned through earphones. The results show that detection thresholds are affected in complicated ways by Q, center frequency, and signal type. This makes their detection difficult to predict using current hearing models and frequency response measurements.
