with an occluding earmold; data above “0” suggest a gain increase (from resonance) while that below “0” suggest gain reduction with the specific vent dimension (length and diameter). The solid line shows the result of a 6 mmlong vent, while the dotted line shows that of a 22 mm-long vent. For both vent lengths, one sees more low-frequency gain reduction as the vent diameter increases. For example, one sees that the output at 200 Hz is reduced by 7-8 dB with a 1 mm vent diameter, but as much as… CONTINUE READING
