  Acoustics  \A*cous"tics\  (#;  277),  n.  [Names  of  sciences  in  -ics, 
  as  acoustics,  mathematics,  etc.,  are  usually  treated  as 
  singular.  See  {-ics}.]  (Physics.) 
  The  science  of  sounds,  teaching  their  nature,  phenomena,  and 
  laws. 
 
  Acoustics,  then,  or  the  science  of  sound,  is  a  very 
  considerable  branch  of  physics.  --Sir  J. 
  Herschel. 
 
  Note:  The  science  is  by  some  writers,  divided,  into 
  diacoustics,  which  explains  the  properties  of  sounds 
  coming  directly  from  the  ear;  and  catacoustica  which 
  treats  of  reflected  sounds  or  echoes.
