Abstract
A sound amplifying bowl assembly includes a grommet has an inner lip that is spaced from an outer lip to define an engaging slot between the inner lip and the outer lip. The inner lip is extendable through an ear hole in a helmet thereby facilitating a bounding edge of the ear hole to engage the engaging slot. In this way the grommet is retained in the ear hole. The grommet has a sound hole extending therethrough to pass audible sound into the helmet. A bowl is integrated into the grommet and the bowl is concavely arcuate such that a curvature of the bowl has a focus that is aligned with the sound hole in the grommet. In this way the bowl can direct the audible sound into the ear hole. Thus, the bowl enhances a user's ability to hear the audible sound when the user is wearing the helmet.
