Numerical optimization for loudspeaker and microphone arrays
Arrays of loudspeakers are often used for sound reinforcement in large concert halls, auditoria, houses of worship and outdoor events. Arrays of microphones have long been used in applications such as sonar and tomography, and are becoming more important for things like teleconferencing. Global optimization techniques such as Stochastic Region Contraction can be combined with previously develop...
متن کاملFull-duplex communication systems using loudspeaker arrays and microphone arrays
For high-quality multimedia communication systems, such as teleconferencing, or tele-teaching (especially of music), multichannel sound reproduction is highly desirable. While current approaches still rely on a restrained listening area, the sweet spot, a volume solution for a large listening space is offered by the Wave Field Synthesis (WFS) method, where arrays of loudspeakers generate a pres...
متن کاملSegmenting multiple concurrent speakers using microphone arrays
Speaker turn detection is an important task for many speech processing applications. However, accurate segmentation can be hard to achieve if there are multiple concurrent speakers (overlap), as is typically the case in multi-party conversations. In such cases, the location of the speaker, as measured using a microphone array, may provide greater discrimination than traditional spectral feature...
متن کاملFabrication and investigation of a transparent and flexible loudspeaker and microphone based on carbon nanotube
Transparent acoustic sensors and actuators are a new generation of acoustic transducers that can create an evolution in the microphone and loudspeakers industries. These transducers with properties like transparency, flexibility, flatness, very low weight and thickness have a great potential for various applications like public speakers, active noise cancelation systems, displays, cell phones a...
متن کاملAcoustic positioning using multiple microphone arrays.
Passive acoustic techniques are presented to solve the localization problem of a sound source in three-dimensional space using off-the-shelf hardware. Multiple microphone arrays are employed, which operate independently, in estimating the direction of arrival of sound, or, equivalently, a direction vector from the array's geometric center towards the source. Direction vectors and array centers ...
