Purpose: The present study aimed to identify the overall patterns of spatial hearing in a sample population geriatric wearing aid an actual clinical setting and investigate while paying attention aging effects separation on informational masking (IM) target speech common types noise everyday life.Methods: Nine participants (mean age: 68.9 ± 9.6) aids participated. abilities were assessed by mea...

Frequency selectivity, temporal fine-structure (TFS) processing, and speech reception were assessed for six normal-hearing (NH) listeners, ten sensorineurally hearing-impaired (HI) listeners with similar high-frequency losses, and two listeners with an obscure dysfunction (OD). TFS processing was investigated at low frequencies in regions of normal hearing, through measurements of binaural mask...

In native speech, durational patterns convey linguistically relevant phenomena such as phrase structure, lexical stress, rhythm, and word boundaries. The lower intelligibility of non-native speech may be partly due to its deviant durational patterns. The present study aims to quantify the relative contributions of non-native durational patterns and of non-native speech sounds to intelligibility...

Speech utterances in a given language are known to be less intelligible to second-language (L2) listeners than to native listeners. This study is aimed at quantifying the reduction of speech intelligibility due to non-nativeness of the listener. Two types of experiments were carried out: Speech Reception Threshold (SRT) experiments for obtaining a quantitative measure of speech intelligibility,...

Hearing aid benefit was measured for three matched groups of eleven hearing-impaired subjects, each serving in one typical listening environment. Benefit was quantified in terms of improvement in intelligibility score for the Connected Speech Test. Each subject was individually fitted with three hearing aids, differing in nominal frequency response slope by a total of 8 dB/octave. Research ques...

OBJECTIVE To evaluate the improvement in speech intelligibility in noise obtained with an assistive real-time fixed endfire array of bidirectional microphones in comparison with an omnidirectional hearing aid microphone in a realistic environment. DESIGN The microphone array was evaluated physically in anechoic and reverberant conditions. Perceptual tests of speech intelligibility in noise we...

This letter presents the C/N requirements for DVB-T2 fixed reception. Results have been obtained from field trials carried out to test DVB-T2 performance, considering outdoor rooftop antenna scenario. Two commercial receivers have been used to obtain C/N threshold values for image error-free condition. The tested configuration modes are the ones recommended for this scenario: 32K FFT and 64 and...

OBJECTIVE The primary objective of the study was to investigate the feasibility, reliability, and validity of the Dutch digits in noise (DIN) test for measuring speech recognition in hearing aid and cochlear implant users and compare results to the standard sentences-in-noise (SIN) test. DESIGN The relation between speech reception thresholds for DIN test and SIN test was analysed to determin...

The Nucleus(®) 5 System Sound Processor (CP810, Cochlear™, Macquarie University, NSW, Australia) contains two omnidirectional microphones. They can be configured as a fixed directional microphone combination (called Zoom) or as an adaptive beamformer (called Beam), which adjusts the directivity continuously to maximally reduce the interfering noise. Initial evaluation studies with the CP810 had...

The most common complaint of older hearing impaired (OHI) listeners is difficulty understanding speech in the presence of noise. However, tests of consonant-identification and sentence reception threshold (SeRT) provide different perspectives on the magnitude of impairment. Here we quantified speech perception difficulties in 24 OHI listeners in unaided and aided conditions by analyzing (1) con...
