Personal Audio Loudspeaker Array as a Complementary TV Sound System for the Hard of Hearing
IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences, 2014 A directional array radiator is presented, the aim of which is to enhance the sound of the television in a particular direction and hence provide a volume boost to improve speech intelligibility for the hard of hearing. The sound radiated by the array in

Loudspeaker Equalization with Post-Processing
EURASIP Journal on Advances in Signal Processing, 2002 Loudspeaker equalization is an essential technique in audio system design. A well-known equalization scheme is based on the deconvolution of the desired equalized response with the measured impulse response of the loudspeaker.

On the characterization of Pethő's Loudspeaker [PDF]
arXiv, 2014 For $d \in \mathbb{N}$ and $\mathbf{r} \in \mathbb{C}^d$ let $\gamma_\mathbf{r}: \mathbb{Z}[\mathrm{i}]^d \to \mathbb{Z}[\mathrm{i}]^d$, where $\gamma_\mathbf{r}(\mathbf{a})=(a_2,...,a_d,$ $-\lfloor\mathbf{r}\mathbf{a}\rfloor)$ for $\mathbf{a}=(a_1,...,a_d)$, denote the (d-dimensional) Gaussian shift radix system associated with $\mathbf{r}$.

Assessment of sound spatialisation algorithms for sonic rendering with headsets [PDF]
arXiv, 2017 Given an input sound signal and a target virtual sound source, sound spatialisation algorithms manipulate the signal so that a listener perceives it as though it were emitted from the target source. There exist several established spatialisation approaches that deliver satisfactory results when loudspeakers are used to playback the manipulated signal ...

Measurement of nonlinear and Doppler distortion in Distributed Mode Loudspeakers [PDF]
International Journal of Electronics and TelecommunicationsDistributed Mode Loudspeakers (DMLs), as other electroacoustic transducers with electrodynamic excitation, are susceptible to the occurrence of nonlinear distortion. The literature on nonlinear distortion in DMLs is scarce.

Loudspeaker Beamforming to Enhance Speech Recognition Performance of Voice Driven Applications [PDF]
arXivIn this paper we propose a robust loudspeaker beamforming algorithm which is used to enhance the performance of voice driven applications in scenarios where the loudspeakers introduce the majority of the noise, e.g. when music is playing loudly. The loudspeaker beamformer modifies the loudspeaker playback signals to create a low-acoustic-energy region ...

Motion Sensor-based Privacy Attack on Smartphones [PDF]
arXiv, 2019 In this paper, we build a speech privacy attack that exploits speech reverberations generated from a smartphone's in-built loudspeaker captured via a zero-permission motion sensor (accelerometer). We design our attack Spearphone2, and demonstrate that speech reverberations from inbuilt loudspeakers, at an appropriate loudness, can impact the ...
