Maximum length sequence and Bessel diffusers using active technologies
Active technologies can enable room acoustic diffusers to operate over a wider bandwidth than passive devices, by extending the bass response. Active impedance control can be used to generate surface impedance distributions which cause wavefront dispersion, as opposed to the more normal absorptive or pressure-cancelling target functions. This paper details the development of two new types of ac...
متن کاملMaximum Margin Active Learning for Sequence Labeling with Different Length
Sequence labeling problem is commonly encountered in many natural language and query processing tasks. SVM is a supervised learning algorithm that provides a flexible and effective way to solve this problem. However, a large amount of training examples is often required to train SVM, which can be costly for many applications that generate long and complex sequence data. This paper proposes an a...
متن کاملTernary and quadriphase sequence diffusers.
A room acoustic diffuser breaks up reflected wavefronts, and this can be achieved by presenting a spatially varying surface impedance. In hybrid surfaces, varying impedance is achieved by patches of absorption and reflection, giving reflection coefficients nominally of 0 and 1. These surfaces are hybrids, absorbing some of the incident sound while diffusing any reflected energy. A problem with ...
متن کاملLüke and power residue sequence diffusers.
Conventional Schroeder diffusers have been successfully used for many years. However, their frequency range is limited by the flat plate effect that occurs when all the wells radiate in phase. This occurs at harmonics of p times the design frequency f(0), where p is the small prime that is used to generate the structure. A typical diffuser, using p=7 and f(0)=500 Hz, has an upper frequency limi...
متن کاملActive Diffusers: Some Prototypes and 2D Measurements
Diffusing devices are used to improve room acoustics in a wide variety of applications. The dispersion generated by current diffuser technologies is often limited to midto high frequencies because low frequency diffusers are usually too large to be easily accommodated. To extend the bandwidth of diffusers to a lower frequency a new approach is proposed, that is to use active control technology....
