The symptom of poor speech discrimination in the presence of background noise is a well-recognized feature of elevated hearing thresholds due to cochlear damage. Similar symptoms occasionally occur in patients with no detectable audiological abnormality. In a study to evaluate the frequency selectivity of such patients consistent abnormalities were found using an electrophysiological technique based on extratympanic electrocochleography. These findings indicated that frequency specific…

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.
Auditory filter shapes and high-frequency hearing in adults who have impaired speech in noise performance despite clinically normal audiograms.
The results strengthen the idea that this population of adults who self-reported speech recognition problems in noise and performed poorly on a sentence-in-noise perception test despite having clinically normal audiograms have a variety of hearing deficits that go undetected by standard audiometry.
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.
A clinical test battery for obscure auditory dysfunction (OAD): development, selection and use of tests.
A demographic and clinical characterization of a sample of 50 OAD patients is summarized, new norms on the tests in the version issued, and a test package developed from a case-control research study that can be routinely used with Oad patients is described.
Loud Music Exposure and Cochlear Synaptopathy in Young Adults: Isolated Auditory Brainstem Response Effects but No Perceptual Consequences
The results demonstrated that a history of loud music exposure can lead to a profile of peripheral auditory function that is consistent with an interpretation of cochlear synaptopathy in humans, namely, modestly abnormal auditory brainstem response Wave I/Wave V ratios in the presence of normal distortion product otoacoustic emissions and normal audiometric thresholds.
Separating the Causes of Listening Difficulties in Children
A plausible, and hopefully noncontroversial, model of speech understanding that comprises auditory processing, speech processing, and language processing, all potentially affected by the degree of attention applied and the listener's memory ability is used.
Early detection of hearing damage in young listeners resulting from exposure to amplified music.
It is concluded that exposure to amplified music can be harmful, the earliest sign being decrease in frequency resolution, and that early elevation of thresholds is better detected by high-resolution Békésy tracking (extending over the range 2-8 kHz) than by conventional fixed-frequency audiometry.
Relations between frequency selectivity, temporal fine-structure processing, and speech reception in impaired hearing.
While a correlation was observed between the monaural and binaural TFS-processing deficits in the HI listeners, no relation was found between TFS processing and frequency selectivity and the results provide constraints for future models of impaired auditory signal processing.


Frequency selectivity and temporal resolution in normal and hearing-impaired listeners.

It is concluded that the loss of frequency and temporal resolution accompanying cochlear hearing loss is a major cause of the difficulties encountered by the hearing impaired in understanding speech in noisy situations.
The present report describes the behavior of single auditory fibers and stresses similarities to other sensory nerves; in a subsequent paper it is hoped to relate these findings to a specific theory of action of the mammalian cochlea.
Intracellular studies of hair cells in the mammalian cochlea.
Intracellular recordings were made from inner hair cells in the first turn of the guinea‐pig cochlea, the recording sites being confirmed by the injection of Procion yellow dye and subsequent histology, and a map of the basilar membrane showing position of hair cells against characteristic frequency corresponded to the cut‐off frequencies of the Basilar membrane mechanical measurements and the innervation sites of spiral ganglion cells.
Aberrant tonotopic organization in the inner ear damaged by kanamycin.
Results show that kanamycin poisoning leads to a loss of sharp, sensitive tuning and a shift to lower frequencies in the tuning curves from a damaged region, and the normal tonoptic pattern of organization is greatly disrupted in the damaged cochleas.
