The Cancellation Principle in Acoustic Scene Analysis
نویسنده
چکیده
Cancellation is a process by which an interfering source (the “jammer”) is removed from a mixture of sounds on the basis of its structure. This is part of the task of “scene analysis” that confronts natural organisms and artificial devices. Jammer cancellation is distinct from, and complementary to, target enhancement. Time-domain cancellation filters are distinct from, and complementary to, time-frequency analysis filters. The cancellation principle is probably used by the auditory system to analyze acoustic scenes on the basis of the spatial or harmonic structure of interfering sources. It is related to modern techniques such as ICA (Independent Components Analysis).

Second, jammer cancellation works well in situations where SNR is unfavorable (for which segregation is most needed). In that case estimating jammer structure is easy, whereas estimating target structure is hard. Cancellation has two weaknesses. The first is that the jammer m...
متن کاملA Framework for Music-Speech Segregation using Music Fingerprinting and Acoustic Echo Cancellation Principle
Background interference creates voice intelligibility issue for listener. This research work considers background music as interference for communication through smart phone in areas with loud background music. This paper proposes a novel framework for background music segregation from human speech using music fingerprinting and acoustic echo cancellation. Initially, background music is searche...
متن کاملRecursive filter estimation for feedforward noise cancellation with acoustic coupling
The basic principle of feedforward noise cancellation for broadband active noise reduction is based on the availability of a reliable measurement of the noise source. Reliability is compromised in case the noise measurement is acoustically coupled to the actual active noise cancellation (ANC), as stability and performance of the feedforward compensation becomes ambiguous. This paper presents a ...
