[The audio-visually determined reaction evaluation test (A-V-R test) (a hearing test for infants and small children)].

The A-V-R-test is accomplished in a free sound field, either with a play audio-metric table (clinical use) or with a textile paravent (practice). The main effort of this reactiontest is the auditive-visual determination. The examiner provokes the auditive readiness with a supraliminal impulse, which prepares the starting position for offering an acoustic test impulse in a low signal strength on the left or right side. If the test is realized with the textile paravent, frequency and intensity proved music instruments or other sound producing objects (bunch of keys, Ewing-rattle, etc.) are offered to the child. If the A-V-R-test is accomplished with the play-audio-metric table, the tester presents a frequency specific narrow band noise to the examinee. Only the turn of the infant's head towards the source of the sound is evaluated. Infants older than 2 years may show specific reactions, depending on the stage of their development.

Finding an effective hearing testing protocol to identify hearing loss and middle ear disease in school-aged children.

This descriptive study defined an effective hearing testing protocol for elementary school-aged children (N = 41). It compared the identification of hearing loss and middle ear disease using pure tone threshold audiometry with tympanometry to using pure tone threshold audiometry. Betty Neuman's Systems Model was used as the conceptual framework for this study. Results showed that a greater number of ears were identified with middle ear disease using the research protocol (n = 22) than would have been identified with middle ear disease (n = 9) using pure tone audiometry alone. The same number of ears (n = 26) were identified with hearing loss using either method. The study further demonstrates a difference between the first and second hearing test results using the specified protocol that validates the necessity for repeating the two tests after 4 weeks before making referrals.

Correlations between audiogram and objective hearing tests in sensorineural hearing loss.

Owing to its subjective nature, behavioral pure-tone audiometry often is an unreliable testing method in uncooperative subjects, and assessing the true hearing threshold becomes difficult. In such cases, objective tests are used for hearing-threshold determination (i.e., auditory brainstem evoked potentials [ABEP] and frequency-specific auditory evoked potentials: slow negative response at 10 msec [SN-10]). The purpose of this study was to evaluate the correlation between pure-tone audiogram shape and the predictive accuracy of SN-10 and ABEP in normal controls and in patients suffering from sensorineural hearing loss (SNHL). One-hundred-and-fifty subjects aged 15 to 70, some with normal hearing and the remainder with SNHL, were tested prospectively in a double-blind design. The battery of tests included pure-tone audiometry (air and bone conduction), speech reception threshold, ABEP, and SN-10. Patients with SNHL were divided into four categories according to audiogram shape (i.e., flat, ascending, descending, and all other shapes). The results showed that ABEP predicts behavioral thresholds at 3 kHz and 4 kHz in cases of high-frequency hearing loss. Also demonstrated was that ABEP threshold estimation at 3 kHz was not affected significantly by audiogram contour. A good correlation was observed between SN-10 and psychoacoustic thresholds at 1 kHz, the only exception being the group of subjects with ascending audiogram, in which SN-10 overestimated the hearing threshold.

[Value of preliminary hearing tests].

Investigation of hearing with whispered and colloquial speech and also tuning fork tests are used routinely by many otologists. A different group of otologists find the tests inconsistent and unreliable. This controversy has probably developed because the audiometer has replaced the tuning fork in hearing measurement. The hearing tests with the whispered and colloquial speech are also a little unsafe. However, they are important orientating hearing tests checking the result of audiometry. Some principles of the investigation of hearing with whispered and colloquial speech and the Weber- and Rinne-tuning fork test are shortly described. The necessary control of pure tone audiometry by tuning forks is pointed out. The value particularly in the diagnosis of conductive hearing loss, and the limitations of informal hearing tests and tuning forks are discussed.

Intermediate hearing tests as predictors of hearing aid acceptance.

This prospective study analyses the ability of several different intermediate hearing screening techniques to predict hearing aid acceptance in a pre-retirement population. In addition to the traditional methods of using sensitivity and specificity to analyse test performance, signal detection theory has been used to obtain a single detectability rate for each test. Questionnaires were able to identify individuals with hearing difficulties but included a significant group of people who ultimately would not accept a hearing aid. This group could be eliminated either clinically using free field speech testing, or audiometrically using warble tone thresholds, without the need for formal pure tone audiometry.

[Physiologic validation of the method of functional hearing tests for evaluation of hearing function].

Physiological validation is presented for application of ototopicometry. This method is intended for measurements of minimal recognizable angles of a moving sound object localization in several space planes. Quantitative characteristics of ototopical function in healthy subjects upon localization of various sound stimuli are described. Ototopicometry is proposed as an additional audiological test for functional assessment of the acoustic human system.

Development of a hearing test protocol for profoundly involved multi-handicapped children.

The purpose of the present study was to develop a protocol for use in testing the hearing of profoundly involved multi-handicapped children. Behavioral observation audiometry, visual reinforcement audiometry, auditory brain stem response (ABR), and noise-tone-difference tests were administered to 156 children with multiple handicaps. Eighty-three percent of the children with normal middle ear function were estimated to have normal hearing or, at worst, a mild hearing loss, by one or more of the tests. ABR was the single best test, followed by behavioral observation audiometry and noise-tone-difference. However, only 65% of the children would have passed had they only been tested with ABR. If agreement among two of the tests had been required, hearing loss would have been ruled out in only 34% of the children. A factor analysis revealed that the various hearing tests were associated with different medical and physical conditions which might influence threshold estimation for multi-handicapped children. These results support use of a series-positive test battery protocol in which individual tests are used sequentially with the purpose of ruling out moderate-profound sensorineural hearing loss.

Correlation between the American Academy of Otolaryngology-Head and Neck Surgery five-minute hearing test and standard audiologic data.

The American Academy of Otolaryngology-Head and Neck Surgery recently developed a questionnaire called the "Five-Minute Hearing Test" and distributed it to many primary care physicians. Our literature review suggests that the test characteristics (i.e., sensitivity and specificity) of this screening instrument have not been published. The purpose of this study was to examine the validity of the test by correlating the "Five-Minute Hearing Test" results to various audiologic results obtained for the same patients and to analyze the test characteristics with pure-tone measures as a standard criterion. An original version of the "Five-Minute Hearing Test" was administered to 70 patients older than 55 years, and a revised version of the test was administered to additional 74 elderly patients. The "Five-Minute Hearing Test" scores in both original and revised versions significantly correlated with all audiologic measures, especially with the pure-tone measures. However, the American Academy of Otolaryngology-Head and Neck Surgery's recommended cutoff score for a referral yielded a high false-positive rate. If the cutoff score were changed, the "Five-Minute Hearing Test" would be a reliable hearing screening tool for identification of hearing loss among the elderly population. Specific recommendations include adjustment of the cutoff score to at least 15 and revision of a few selected test items.
