Confusion Matrices

Consonant confusion matrices were obtained from 22 outpatient listeners with sensorineural hearing loss for four sets of CV and VC nonsense syllables, presented monaurally at SRT + 40 dB. Testing was typically conducted for six hours on each of two separate days. Overall performance and patterns of confusions were stable over time. Analysis of the matrices in terms of phonological features indicated that the patterns of consonant confusions varied both with degree and configuration of the subject’s loss. Scaling of intersubject similarity using a pairwise multidimensional scaling analysis resulted in consistent classification of subjects according to audiometric configuration into three groups-essentially normal hearing, flat or rising audiograms, and high-frequency hearing losses.

High Pass

It has been found that listeners with sensorineural hearing loss who show similar patterns of consonant confusions also tend to have similar audiometric profiles. The present study determined whether normal listeners, presented with filtered speech, would produce consonant confusions similar to those previously reported for the hearing-impaired listener. Consonant confusion matrices were obtained from eight normal-hearing subjects for four sets of CV and VC nonsense syllables presented under six high-pass and six low-pass filtering conditions. Patterns of consonant confusion for each condition were described using phonological features in a sequential information analysis. Severe low-pass filtering produced consonant confusions comparable to those of listeners with high-frequency hearing loss. Severe high-pass filtering gave a result comparable to that of patients with flat or rising audiograms. And, mild filtering resulted in confusion patterns comparable to those of listeners with essentially normal hearing. An explanation in terms of the spectrum, the level of speech, and the configuration of the individual listener’s audiogram is given.

Confusion Matrices

The effects of consonantal context on vowel lipreading were assessed for 30 adults with mild-to-moderate sensorineural hearing loss who lipread videotape recordings of two female talkers. The stimuli were the vowels /i, I ,, U ,u/ in symmetric CVC form with the consonants /p,b,f,v,t,d,∫,g/ and in the asymmetric consonantal contexts /h/-V-/g/, /w/-V-/g/, /r/-V-/g/. Analyses of the confusion matrices from each talker indicated that vowel intelligibility was significantly poorer in most contexts involving highly visible consonants, although the utterances of one talker were highly intelligible in the bilabial context. Among the visible contexts, the fricative and labiodental contexts in particular produced the lowest vowel intelligibility regardless of talker. Lax vowels were consistently more difficult to perceive than tense vowels. Implications for talker selection and refinement of the concept of viseme were drawn.

The significance of asymmetric sensorineural hearing loss (ASNHL) is due to a special approach to diagnosis, followed by the process of hearing aids and auditory rehabilitation. Currently, there is no standard audiometric criterion for determining the forms of asymmetry, which significantly affects the assessment of the prevalence of ASNHL. The study aimed to assess the prevalence and classification of ASNHL forms in the older age group using two methods of calculation: 1) the difference in the average hearing threshold at speech frequencies (in the range of 0,5–4 kHz) ≥15 dB was detected in 14,14% of cases; 2) the different degree of hearing loss, according to the International classification, in the right and left ear was 35,98%. In most cases, asymmetry was manifested by bilateral sensorineural hearing loss of varying severity, prevailing in the group of long-livers – 82,6%. Given the potentially high prevalence of asymmetry depending on the audiological criterion, the results of the work are a reason for further research in the development of a unified method for verifying a clinically significant form of ASNHL.

<p>Sudden Hearing loss has been rarely reported as a presenting symptom of malaria fever. It’s even more rare to have a bilateral profound sudden sensorineural hearing loss. A 19 years old female student presented with fever, body weakness, hearing loss with tinnitus. Laboratory investigations done were essentially normal except blood film for malaria parasite which showed a high concentration of the parasite in blood on both occasions. Otoacoustics emission test was passed bilaterally while auditory steady state response showed profound hearing loss bilaterally. Normal hearing was restored within 48 hrs of commencement of anti-malaria drugs and low dose steroids. </p>

Fluctuating Hearing Loss

Five cases are presented of children with rapid onset of sensorineural hearing loss, disequilibrium, or both, who were found at exploratory tympanotomy to have a perilymph fistula. Four of the children had histories suggesting that antecedent barotrauma or physical exertion contributed to the development of the fistula. One child with congenital unilateral craniosynostosis had a residual temporal bone abnormality on the same side as the perilymph fistula. Two children had identifiable anatomic abnormalities in the middle ear. A classification of perilymph fistula is proposed that describes a congenital, an acquired, and a combined type of fistula. Inner ear fluid dynamics and patency of the cochlear aqueduct appear to be important factors in pathogenesis. Children with unexplained fluctuating or sudden onset of sensorineural hearing loss, and children with unexplained disequilibrium or vertigo should be suspected of having a perilymph fistula. The history can be singularly important in raising the suspicion that a perilymph fistula may be present. Although audiometric, vestibular, and radiographic studies can be helpful, there is no way to prove the presence or absence of a fistula without directly viewing the middle ear. Tympanotomy with repair of the fistula does not assure improvement in hearing.
