A usual rhinomanometer was used to construct an apparatus to measure the aerodynamic resistance of a tracheostomy speaking tube lying in the trachea. This resistance, evoked by the sieve or the hole in the tube, is considerable. A model of a trachea was made from a silicone tube to assess the resistance of several types of tracheostomy speaking tubes.
