Emulating the auditory sense is a significant challenge in terms of both integration and energy consumption for handling complicated spatiotemporal information. Here, we demonstrate how to utilize chaotic dynamics threshold switching memristor, which usually acts as leaky integrate fire neuron neuromorphic network, encode frequency amplitude We fabricate Pd/Nb/NbOx/Nb/Pd memristor dominated by ...

Adult canaries (Serinus canarius) from a closebred colony of the Belgian "Waterslager" strain were trained with operant techniques to respond to pure tones. A psychophysical tracking procedure was used to measure absolute auditory thresholds in quiet and in noise. Absolute thresholds in the middle- to high-frequency region of the audiogram were between 30 and 40 dB higher (4-5 standard deviatio...

OBJECTIVE To evaluate the effects of using the Electrode Positioning System on psychophysical auditory thresholds, most comfortable loudness levels, and electric auditory brainstem response (EABR) thresholds in children with the Clarion version 1.2 cochlear implant. DESIGN Retrospective analysis. SETTING Academic tertiary care center. PATIENTS AND METHODS Clinical records of a series of 2...

A psychoacoustic experiment has been conducted to determine the difference limen (DL) of the level of music reproduced in a listening room. The effects of three factors on the DL were measured using up to twelve trained subjects. The factors were music motif (Mozart, Elgar, Smashing Pumpkins), listening level (50, 60, 65, 70, 80 dB, A-weighted Leq) and dynamic range. It was hypothesised that th...

PSYCHOACOUSTICS is a new MATLAB toolbox which implements three classic adaptive procedures for auditory threshold estimation. The first includes those of the Staircase family (method of limits, simple up-down and transformed up-down); the second is the Parameter Estimation by Sequential Testing (PEST); and the third is the Maximum Likelihood Procedure (MLP). The toolbox comes with more than twe...

Vertebrates have evolved mechanisms to exploit amplitude modulations in background noise for improving signal detection. However, the mechanisms underlying this masking release are not yet well understood. Here we present evidence for masking release observed in European starlings (Sturnus vulgaris, Aves) that were trained in a Go/NoGo paradigm to report the detection of a short tone (20 ms) in...

PURPOSE To analyze and characterize tonal auditory thresholds between 500 Hz and 16,000 Hz of professional musicians, specifically members of a military band. METHODS A historic cohort study was carried out comparing one group of 50 professional musicians (military band) with another group (44 subjects) without history of professional exposure to intense sound; the groups were homogenous (p<0...
