Purpose: Growing evidence supports the inclusion of perceptual tests that quantify the processing of temporal fine structure (TFS) in clinical hearing assessment. Many tasks have been used to evaluate TFS in the laboratory that vary greatly in the stimuli used and whether the judgments require monaural or binaural comparisons of TFS. The purpose…

Purpose: This study aimed to evaluate the effects of aging and cochlear implant (CI) on psychoacoustic and speech recognition abilities and to assess the relative contributions of psychoacoustic and demographic factors to speech recognition of older CI (OCI) users. Method: Twelve OCI users, 12 older acoustic-hearing (OAH) listeners age-matched to…

Purpose: Speech recognition in complex listening environments is enhanced by the extent of spatial separation between the speech source and background competing sources, an effect known as spatial release from masking (SRM). The aim of this study was to investigate whether the phase-locked neural activity in the central auditory pathways,…

Purpose: Some researchers have assessed ear-specific performance of auditory processing ability using speech recognition tasks with normative data based on diotic administration. The present study investigated whether monotic and diotic administrations yield similar results using the Selective Auditory Attention Test. Method: Seventy-two typically…

No differences were observed between six adults and six six-year-olds in measures of frequency selectivity and comodulation masking release. Children were less able to detect signals in noise backgrounds where the signal had perceptual qualities similar to the noise or in noise backgrounds having high degrees of fluctuation. (Author/JDD)

One experiment determined that the minimum angle at which infants can discriminate 2 sound presentations decreases substantially toward 48 weeks of age. In 3 succeeding experiments, infants aged 16, 20, and 28 weeks were able to discriminate sounds presented to each ear between 50 and 75 microseconds apart. (BC)

Binaural masked thresholds for a speech sound (/ba/) were estimated under two interaural phase conditions in three age groups (infants, preschoolers, adults). Differences as a function of both age and condition and effects of reducing intensity for adults were significant in indicating possible developmental binaural hearing changes, especially…

Describes the development and evaluation of a computer-administered testing program for auditory discrimination in young children. (WB)

Identifies the "missing fundamental illusion" as that which occurs when two tones are heard together and the listener hears a third tone with a pitch corresponding to the difference in their frequencies. Describes an inexpensive and valid demonstration of the missing fundamental using a British police whistle. (MJP)

APPROXIMATELY 1,300 MENTALLY RETARDED PATIENTS WERE INVOLVED IN A STUDY ON THE ADEQUACY OF HEARING TESTS, THE INCIDENCE OF HEARING LOSS, AND STANDARDIZATION OF PROCEDURES. THE STUDY INCLUDED TEST STANDARDIZATION AND EVALUATION, HEARING SCREENING AND PSYCHOLOGICAL-SOCIAL-OTOLOGICAL EVALUATION, AND HEARING TEST DEVELOPMENT. THE SUBJECTS WHO…

The Speech Reception Test was developed to measure an individual's ability to hear and understand conversational speech. The equipment used to record the test is described in detail, and data are given for the results of the test given to 100 normal-hearing college students. Other data describe the results for 55 military veterans with known…

This report contains estimates of hearing levels for children 6 to 11 years of age in the United States as determined in the second cycle of the Health Examination Survey, conducted during 1963-1965. A probability sample (N=7,119) was selected to represent the 24 million children 6 to 11 years of age in the noninstitutional population. Hearing…

Methods to evaluate central hearing deficiencies and to localize brain damage are reviewed beginning with Bocca who showed that patients with temporal lobe tumors made significantly lower discrimination scores in the ear opposite the tumor when speech signals were distorted. Tests were devised to attempt to pinpoint brain damage on the basis of…

The main purpose of this study was to investigate the validity of the assumption that auditory discrimination and pronunciation in a foreign language are closely related. If the assumption were to be well-founded, then it might be possible for foreign language students with high auditory discrimination ability to work alone in the language…

This book is intended to help professionals differentiate among processing disorders in children in kindergarten through high school so that intervention efforts can become focused and more effective. It explains how to differentiate among processing disorders, discusses the major processing models, explains assessment procedures, and outlines…
