Masking of tinnitus is possible using high audio frequencies and low-frequency ultrasound. The mechanisms involved in reception and perception of both audio frequencies and ultrasound are identical, with the exception that ultrasound interacts with an intermediary site, the brain. We proposed brain ultrasonic demodulation as the means of place-mapping ultrasound on the first few millimeters of ...

This tutorial paper details experiences of four public engagement projects that have communicated acoustic science to lay audiences using web experiments. Recent developments in personal computers, the Internet and software platforms offers new and exciting opportunities for engaging publics because technologies routinely allow the reproduction of sound. The projects are psychoacoustic experime...

This is a tutorial paper giving an introduction to the perception of multichannel sound reproduction. The important underlying psychoacoustic phenomena are reviewed – starting with the behaviour of the auditory periphery and moving on through binaural perception, central binaural phenomena and cognition. The author highlights the way the perception of a recording can be changed according to the...

Substantial progress has been made recently in finding acoustic features that describe perceptually relevant aspects of sound. This paper presents a general framework for synthesizing audio manifesting arbitrary sets of quantifiable acoustic features of the sort used in music information retrieval and other sound analysis applications. The methods described have broad applications to the synthe...

The purpose of this study was to develop a sound quality model for real time active control systems. is based on an optimal analytic wavelet transform (OAWT) used along with back propagation neural network (BPNN) in which the initial weights and thresholds are determined by particle swarm optimisation (PSO). In input signal decomposed into 24 critical bands extract feature matrix, energy, mean,...

The processing of low-frequency interaural time differences is found to be problematic among hearing-impaired people. current generation beamformers does not consider this deficiency. In an attempt tackle issue, we propose replace the inaudible in region with level differences. addition, a beamformer introduced and analyzed, which enhances sound sources using near-field transformation. proposed...

The level of annoyance is an important basis to determine the acceptable degree noise and develop standards. Psychoacoustic ( PA) calculated by Zwicker’s model perceived (such as mean annoyance, MA percentage highly annoyed population, % HA) obtained through individual self-reports are widely used. PA (or %HA) cannot be directly compared because ranges their values different. Thus, conversion r...

Voice Processing Systems (VPSes), now widely deployed, have become deeply involved in people’s daily lives, helping drive the car, unlock smartphone, make online purchases, etc. Unfortunately, recent research has shown that those systems based on deep neural networks are vulnerable to adversarial examples, which attract significant attention VPS security. This review presents a detailed introdu...

Abstract At present, there are two approaches that aim at explaining on physical grounds the psychoacoustic perception of consonance and dissonance for dyads, whose pioneers have been, respectively, Galilei Helmholtz: One is based “compactness” waveform combined signal, while other absence “roughness” due to possible beats. We perform a detailed study each approach find none associated model ve...
