FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
Loudspeaker Acoustics is the study (either scientific or pseudo-scientific) of the behaviour of the loudspeaker and in particular the effort to create loudspeakers with good sound quality (either subjectively or objectively measured). Jump to: navigation, search This article needs to be cleaned up to conform to a higher standard of quality. ...
A number of approaches are used to address different aspects of sound quality, and to usefully model behaviour in different frequency ranges. These include anechoic or simulated-anechoic measurements, resonance and standing-wave measurements etc. They have become significantly easier and more precise with the advent of computers, which allow detailed measurements of various aspects of loudspeaker behavior without the need to resort to (expensive) anechoic rooms. In physics, resonance is the tendency of a system to absorb more oscillatory energy when the frequency of the oscillations matches the systems natural frequency of vibration (its resonant frequency) than it does at other frequencies. ... An anechoic room simulates a free field — a representation of a theoretical infinite space, in which there are no sound wave reflections (echoes). ...
f Sine waves of various frequencies; the lower waves have higher frequencies than those above. ... A Sony 9 inch woofer. ... Jump to: navigation, search Wooden subwoofer A subwoofer is a loudspeaker device which reproduces sub-bass frequencies at the lowest frequencies audible, up to around 60–150 hertz, where the feeling of punch and energy tends to be located in music and movie soundtracks. ... Lumped component model In general, the lumped component model is a way of simplifying the behaviour of spacially distributed systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. ... Acoustics is a branch of physics and is the study of sound, mechanical waves in gases, liquids, and solids. ...
The roll of the acoustic engineer is to verify and evaluate potential solutions and often, as in the case with Bang and Olufsen, develope new technologies and ideas in order to solve a particular problem, such as very limited space.
The loudspeaker is a 2 or 3-way active loudspeaker with an acoustic lens and provides unrivalled imaging and sound performance.
It is an active 2-way loudspeaker with 2 x 250W of power driving a 5" woofer in a closed aluminium cabinet and 3/4" tweeter in an acoustic lens.
