DOI: 10.1121/1.4988606
Abstract: A dodecahedral loudspeaker is commonly used in room acoustical measurements as an omnidirectional sound source. However, inverse filtering to obtain an ideal room impulse response (RIR) is not easy because of its irregular frequency and… read more here.

DOI: 10.1121/1.5068249
Abstract: Room acoustic parameters, including the reverberation time (T60) and the direct-to-reverberant ratio (DRR), quantitatively describe the behaviour of an acoustic environment. These parameters are typically derived from an acoustic impulse response (AIR) obtained using an… read more here.

DOI: 10.3390/act7020028
Abstract: Conventional loudspeakers are often heavy, require substantial design spaces and are hard to integrate into lightweight structures (e.g., panels). To overcome these drawbacks, this paper presents a novel extremely flat loudspeaker which uses dielectric elastomer… read more here.
