Extensions to the Mode Matching Method for Horn Loudspeaker Simulation
Kolbrek, Bjørn (Doctoral thesis at NTNU;2016:280, Doctoral thesis, 2016)For loudspeaker horns, the throat acoustic impedance and the far field directional characteristics are important measures of performance. Both quantities depend greatly on the shape of the horn, and the acoustical ... -
Høyttalersimulering med mode-basert metode
Evensen, Karen Brastad (Master thesis, 2014)I denne masteroppgaven er det tatt utgangspunkt i modellering av sirkulære horn ved Modal metode som beskrevet i \cite{Kemp}. Denne metoden er blitt videreutviklet til å fungere for konkave, vibrerende strukturer ved at ... -
Modal sound propagation in curved horns of rectangular cross-section
Kolbrek, Bjørn (Master thesis, 2013)Wave propagation in horns can be simulated by propagating both the plane wave component and the higher order modes down the horn, as described by Kemp (2002). While this is most common for axisymmetric ducts, the method ...
