In which scenario would a thin tube open dome BTE be selected for fitting?

A thin tube open dome behind-the-ear (BTE) hearing aid is particularly suited for scenarios where low-frequency sounds need to pass through naturally. This design allows for a more open ear canal, which enables natural sounds to enter the ear without significant amplification. It is especially beneficial for individuals with normal low-frequency hearing, as it helps them perceive environmental sounds more clearly while still providing necessary amplification for higher frequencies, where they may require assistance.

This fitting is optimal for people who may struggle with the occlusion effect, which can occur with more closed fittings. An open dome minimizes the build-up of pressure in the ear canal and allows for a more transparent sound experience, making it ideal for preserving the natural quality of low-frequency sounds while providing the appropriate amplification needed.

Other scenarios, such as needing maximum low-frequency gain, maximum feedback control, or a secure fit, would not be the primary reasons for choosing a thin tube open dome design, as those situations typically call for different styles of hearing aids that provide either greater occlusion or stability.
