AI Article Synopsis
- Acoustic-reflex growth functions (ARGFs) were measured in 20 normal-hearing individuals using 2000 Hz tones to assess contralateral acoustic reflexes (ARs).
- Six combinations of probe-tone frequencies (226 Hz, 678 Hz, 1000 Hz) were used to monitor changes in static compliant susceptance (BA) and conductance (GA).
- The highest peak conductance and susceptance ARs were observed with 678 Hz GA and 1000 Hz BA, respectively, showing larger, less variable growth patterns indicated by their polynomial coefficients and squared correlation coefficients (R2).
Article Abstract
Acoustic-reflex growth functions (ARGFs) were obtained from 20 normal-hearing listeners. Contralateral acoustic reflexes (ARs) were elicited with pure tones of 2000 Hz. The magnitude of changes in static compliant susceptance (BA) and conductance (GA) were monitored with probe-tone frequencies of 226 Hz, 678 Hz and 1000 Hz. ARGFs were obtained with six combinations of probe-tone frequency/admittance component: 226 Hz BA, 226 Hz GA, 678 Hz BA, 678 Hz GA, 1000 Hz BA, and 1000 Hz GA. Peak conductance (GA) and susceptance (BA) ARs were largest within the 678 Hz GA and 1000 Hz BAARGFs, respectively. Among high-frequency probe tones, the patterns of AR growth were larger and less variable for the 678 Hz GA ARGF and the 1000 Hz BA ARGF as determined by the magnitude of their linear (b1) and quadratic (b2) polynomial coefficients and the value of their squared correlation coefficients (R2).
