Optimized Driver Placement for Array-Driven Flat-Panel Loudspeakers
Archives of Acoustics, 2017 The recently demonstrated ‘modal crossover network’ method for flat panel loudspeaker tuning employs an array of force drivers to selectively excite one or more panel bending modes from a spectrum of panel bending modes.

The Effect of Interchannel Time Difference on Localisation in Vertical Stereophony [PDF]
, 2015 Listening tests were conducted in order to analyse the localisation of band-limited stimuli in vertical stereophony. The test stimuli were seven octave bands of pink noise, with centre frequencies ranging from 125–8000Hz, as well as broadband pink noise.

Loudspeaker Abnormal Sound Classification Using Auditory Perception Weighted by Energy Entropy
IEEE Access, 2023 In order to improve the classification accuracy of loudspeaker abnormal sounds, this paper proposes a method based on time-varying specific loudness weighted by energy entropy and principal component analysis.

Efficiency of low power audio amplifiers and loudspeakers [PDF]
, 2001 In this paper we look at the load presented to audio amplifiers by real transducers. We consider the power losses in Class-AB and Class-D amplifier topologies, and determine that in order to predict efficiency it is necessary to consider the amplifier ...

Driver Filter Design for Software-implemented Loudspeaker Crossovers
Archives of Acoustics, 2014 A hybrid method is presented for the integration of low-, mid- and high-frequency driver filters in loudspeaker crossovers. The Pascal matrix is exploited to calculate denominators; the locations of minimum values in frequency magnitude responses are ...

Time-Domain Sound Field Reproduction with Pressure and Particle Velocity Jointly Controlled
Applied Sciences, 2021 Particle velocity has been introduced to improve the performance of spatial sound field reproduction systems with an irregular loudspeaker array setup. However, existing systems have only been developed in the frequency domain. In this work, we propose a

On the Frequency Response of Nanostructured Thermoacoustic Loudspeakers
Nanomaterials, 2018 In this work, we investigate the thermal and acoustic frequency responses of nanostructured thermoacoustic loudspeakers. An opposite frequency dependence of thermal and acoustic responses was found independently of the device substrate (Kapton and glass)
