Obscure auditory dysfunction (OAD) is defined as convincing self-report of auditory disability accompanied by normal pure-tone thresholds. This has been increasingly recognized as a clinical problem, but until now there has not been a standard clinical procedure for dealing with such patients. This paper summarizes a demographic and clinical characterization of a sample of 50 OAD patients, reports new norms on the tests in the version issued, and describes a test package developed from a case… 
Validation of parameters for assessing Obscure Auditory Dysfunction--robustness of determinants of OAD status across samples and test methods.
A study on a further 59 new OAD patients and 64 unmatched controls, using the tests in the form present in the test package, plus certain others, confirms the validity of the three-factor model of OAD status and the utility of the clinical test package based upon it.
A pilot investigation of high-frequency audiometry in obscure auditory dysfunction (OAD) patients.
It is proposed that OAD in fact, is the product of an ultra-high-frequency hearing impairment and its psychoacoustic sequelae and the degree to which it can be used may be limited due to the large intersubject variability in HFA thresholds in the normal population.
A critical review of King-Kopetzky syndrome: Hearing difficulties, but normal hearing?
King-Kopetzky syndrome (KKS) is the condition in which an individual complains of having difficulties understanding speech in background noise but has normal hearing thresholds on pure tone
Subcategories of Patients with King-Kopetzky Syndrome
In a study on 110 consecutive patients with King-Kopezky syndrome referred to the Welsh Hearing Insitute, subjects were subdivided into seven subcategorization based on sensitized measures of auditory dysfunction and on psychological assessment, which provides further understanding of the basis ofKing-Kopetzky syndrome.
Auditory tests for characterizing hearing deficits: The BEAR test battery
The results showed the ability of the tests to reveal differences among individuals and their potential use in clinical settings and the analysis of the results showed interrelations among outcomes related to high-frequency processing and outcome measures related to low-frequencyprocessing abilities.
Auditory processing disorders in adults and children: Evaluation of a test battery: Desórdenes del procesamiento auditivo en adultos y niños; evaluación de una batería de pruebas
A Dutch test battery comprising six different tests for auditory processing disorders was evaluated in a group of 49 adults and children with auditory complaints despite normal audiometric thresholds and provided evidence for a model comprising four auditory components: auditory sequencing, word recognition in noise, auditory closure, and auditory patterning.
The Performance-Perceptual Test and Its Relationship to Unaided Reported Handicap
The Performance-Perceptual Test should prove to be a valuable tool for better understanding why some individuals complain of hearing difficulties but have only a mild hearing loss or conversely report few difficulties in the presence of substantial impairment, and would seem to provide both an explanation and a counseling tool for patients for whom there is a mismatch between reported and measured hearing difficulties.
The Influence of Personality‐Related Factors upon Consultation for Two Different “Marginal” Organic Pathologies with and without Reports of Auditory Symptomatology
It is concluded that anxiety-related traits are associated with the seeking of medical attention in general, whereas the hearing-related deficits the authors measured are associated specifically with OAD.
Auditory tests for characterizing hearing deficits in listeners with various hearing abilities: The BEAR test battery
The Better hEAring Rehabilitation (BEAR) project aims to provide a new clinical profiling tool, a test battery, for hearing loss characterization. Whereas the loss of sensitivity can be efficiently
Causal attributions in King-Kopetzky syndrome
The findings suggest that participants regard immunity and risk related causes of hearing difficulties as pre-dominant and psychological factors were not considered to be causal for hearing difficulties.


The clinical assessment of obscure auditory dysfunction--1. Auditory and psychological factors.
We define obscure auditory dysfunction (OAD) as the clinical presentation of reported difficulty understanding speech in the presence of noise accompanied by clinically "normal" hearing thresholds,
The clinical assessment of "Obscure Auditory Dysfunction" (OAD) 2. Case control analysis of determining factors.
Stage 2 of a case control study of OAD has confirmed the general finding of stage 1 that OAD is multifactorial; compared with controls, patients as a group have a genuine performance deficit for understanding speech in noise, accompanied by personality-related factors.
Determinants of objective and subjective auditory disability in patients with normal hearing
A proportion of individuals consulting audiology clinics complain of difficulties discriminating speech in noisy environments but have clinically 'normal' hearing, do not have signs of middle ear
Self-reported disability and handicap in the population in relation to pure-tone threshold, age, sex and type of hearing loss.
A self-administered questionnaire concerning auditory disability and handicap was completed by 1691 subjects who were part of a two-stage random sample of the UK adult population, finding little evidence for the concept of a 'low fence' in the relationship between impairment and either disability or handicap.
Selective Dysacusis — A Preliminary Report
Findings indicated that frequency specific responsiveness of the cochlea may be affected before conventional behavioural tests reveal abnormalities.
A pseudo free-field measure of auditory disability.

A procedure has been developed by recording the signals from two Zwislocki couplers in a KEMAR mannikin to produce a headphone-presented set of speech material containing the important dichotic cues present in free field listening that enables readily calibrated and experimentally controllable conditions to be set up to measure aspects of auditory disability and, for example, its alleviation via amplification.
Dissociation Between Frequency Resolution and Hearing Threshold
This belief is substantiated by two additional observations: a) Pick (1980a) reported evidence which suggested that poor frequency resolution can be dissociated from threshold in TTS, and more recently, clear physiological evidence has been obtained that FTC bandwidths in guinea pig can be impaired, without substantial elevation of threshold, after chronic or acute administration of ototoxic diuretics.
Knowledge of hearing tactics : (I) assessment by questionnaire and inventory
There are many ‘hearing tactics’ that a person can employ to improve communication in adverse listening conditions. Poor knowledge or lack of awareness of these tactics may contribute to the
Sensorineural hearing loss.
