How Do Vents Affect Hearing Aid Performance?

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 examp...

Charities often devise fund-raising strategies that exploit natural human competitiveness in combination with the desire for public recognition. We explore whether institutions promoting competition can affect altruistic giving even when possibilities for public acclaim are minimal. In a controlled laboratory experiment based on a sequential “dictator game”, we find that subjects tend to give m...
