Abstract
A personal hearing device with an outer housing and a sound path with a length of 1-24 mm, a diameter of 0.5-6 mm, a roll of frequency of at least 500 Hz and with a valve configured to open and close the sound path. The sound path has suitable acoustical properties to act as a sound passage for open/closed hearing aids or hearables. The valve is selected to have a small influence on the acoustical properties of the remaining portions of the sound path.
