A digital filter for stochastic systems with unknown structure and its application to psychological evaluation of sound environment

A. Ikuta;H. Masuike;M. Ohta

Publication Year: 2004,Page(s):II - II
Cited by: Papers (1)
The actual sound environment system exhibits various types of linear and nonlinear characteristics, and it often contains an unknown structure. Furthermore, the observations in the sound environment are often in the level-quantized form. In this paper, a method for estimating the specific signal for a sound environment system with unknown structure and the quantized observation is proposed by intr...Show More

A new narrowband active noise control system in the presence of sensor error

Yegui Xiao;Liying Ma;K. Khorasani;A. Ikuta

Publication Year: 2004,Page(s):II - II
Cited by: Papers (1)
Narrowband active noise control (ANC) systems have many real-life applications where the noise signals generated by rotating machines are modeled as sinusoidal signals in additive noise. However, when the timing signal sensor, such as a tachometer that is used to extract the signal frequencies, and the cosine wave generator contain errors, the reference signal frequencies fed to each ANC channel w...Show More

Convergence analysis of linear and nonlinear filtered-X LMS algorithms for active control of multitonal noise

Y. Hinamoto;H. Sakai

Publication Year: 2004,Page(s):II - II
Cited by: Papers (1)
In the presence of tonal noise generated by periodic noise source like rotating machines, the filtered-X LMS algorithm is used for active control of such noises. However, the algorithm is derived under the assumption of slow adaptation limit and the exact analysis of the algorithm is restricted to the case of one real sinusoid in the literature. In this paper for the general case of arbitrary numb...Show More

Frequency domain de-correlation parameter in speech noise reduction system based on frequency domain adaptive line enhancer

I. Nakanishi;T. Asakura;Y. Itoh;Y. Fukui

Publication Year: 2004,Page(s):II - II
Cited by: Papers (3)
A speech noise reduction system based on a frequency domain adaptive line enhancer has been proposed. The adaptive line enhancer (ALE) is effective to extract sinusoidal signals blurred by a broadband noise and utilizes only one microphone; therefore, it is suitable for realization of speech noise reduction in the portable electronic devices. Moreover, the noise reduction system adopts the frequen...Show More

On the improvement of acoustic feedback cancellation in hearing-aid

A. Chankawee;N. Tangsangiumvisai

Publication Year: 2004,Page(s):II - II
Cited by: Patents (3)
This paper presents a decorrelation technique to improve the performance of acoustic feedback cancellation in hearing aids, particularly for the continuous adaptation approach. It is proposed that the input and the output signals of the hearing aids are decorrelated via the use of higher-order time-varying allpass filters in order to adequately decorrelate the signals with as little degradation of...Show More
