The Ear and the Voice. The delicate structure of the 

 ear is fully matched by the fine adjustment and range of 

 the voice. The voice is produced in the larynx at the upper 

 end of the windpipe. The projecting angle of the larynx 

 is called " Adam's apple."

 They are mere ridges projecting inward from the sides of 

 the larynx. They maybe stretched to various degrees and 

 placed in different positions, according to the sound that
