Real Ear Compression Ratios

  title={Real Ear Compression Ratios},
  author={Todd W. Fortune},
An investigation was conducted to determine the effects of vent diameter, stimulus characteristics, and adaptive release time on the real ear compression ratio (CR). Real ear input/output (I/O) functions generated in response to syllables and speech-shaped noise revealed that the real ear CR is often less than the nominal value measured in the coupler, but only for CRs greater than 2:1. Results were similar across all vents except IROS, a condition that resulted in much larger errors than… CONTINUE READING
