Abstract
The present invention proves an elbow shaped connector for connecting flexible sound conduction tubing from a hearing aid to a conventional earmold. The sound bore of the connector has an increasing diameter to improve high frequency response. This increase in diameter may be gradual, over the length of the connector, or it may occur abruptly at some point within the connector.
