A point collocation approach to modelling large dissipative silencers [PDF]
, 2005 A numerical matching technique known as point collocation is used to model mathematically large dissipative splitter silencers of a type commonly found in HVAC ducts. Transmission loss predictions obtained using point collocation are compared with exact

Sound transmission in the thorax [PDF]
The Journal of the Acoustical Society of America, 1974 The use of an intracardiac sound source to determine transfer functions and propagation paths and modes for the thorax using digitial data reduction techniques is discussed. It is important to know the sound transmission characteristics of the thorax for diagnostic purposes.
