Experiments conducted on an electrical analogue of the acoustical reflection process have allowed the cepstral technique to be developed and evaluated.
The acoustical reflection and transmission properties of flat plates in water are of relevance to the behaviour of submerged structures exposed to waterborne sound waves.
Good agreement is obtained between theoritical and measured transfer functions for a variety of filter networks indicating that cepstral techniques may be useful for acoustical reflection measurements given adequate transducer properties and environmental conditions.
The resonance in my head was in-sync with its acoustical reflection in the room.
Another complication was that like many concert halls designed by Russell Johnson, chief acoustician of Artec Consultants, Verizon Hall has adjustable elements built into it: a three-piece canopy suspended above the stage for sound reflection and 100 acoustical closets (as everyone has taken to calling them) that encircle the auditorium and can be opened fully, partially or not at all.
Experiments were conducted in an anechoic chamber, thus reducing acoustical interferences from the environment and reflections of call signals.
In this paper are described laboratory acoustical measurements of the normal incidence reflection coefficient of an absorbent material: emphasis is placed on practical aspects of the technique.
Covering all aspects of composition with sound particles, Microsound offers composition theory, historical accounts, technical overviews, acoustical experiments, descriptions of musical works, and aesthetic reflections.
This paper proposes a pulse method for estimating the acoustical performance of absorptive panels to reduce noise reflections when applied to road structures such as parallel walls and ceilings of double deck viaducts.
This method can be used to determine some acoustical characteristics of an absorbing sample (such as the reflection coefficient, characteristic acoustic impedance, and sound absorption coefficient) from the specific acoustic impedance.
Interactions of acoustical waves with obstacles, on the path from the source to the observation point, are reduced to specular reflections from surfaces and diffraction at edges (wedges) of obstacles.
