Compressed Speech

This study explored whether the time-compressed speech perception varied with the degree of hearing loss in high-frequency sensorineural hearing loss (HF SNHL) individuals. 65 HF SNHL individuals with different cutoff frequencies were recruited and further divided into mildly, moderately, and/or severely affected subgroups in terms of the averaged thresholds of all frequencies exhibiting hearing loss. Time-compressed speech recognition scores under both quiet and noisy conditions and gap detection thresholds within low frequencies that had normal thresholds were obtained from all patients and compared with data from 11 age-matched individuals with normal hearing threshold at all frequencies. Correlations of the time-compressed speech recognition scores with the extents of HF SNHL and with the 1 kHz gap detection thresholds were studied across all participants. We found that the time-compressed speech recognition scores were significantly affected by and correlated with the extents of HF SNHL. The time-compressed speech recognition scores also correlated with the 1 kHz gap detection thresholds except when the compression ratio of speech was 0.8 under quiet condition. Above all, the extents of HF SNHL were significantly correlated with the 1 kHz gap thresholds.

Significant Difference

Objective: We investigated the incidence of sensorineural hearing loss (SNHL) after chronic otitis media (COM) surgery and determined the associated factors. Methods: Data were collected via retrospective medical chart review. Results: Of the 192 patients, 82 underwent tympanoplasty, 26 underwent canal wall up mastoidectomy with tympanoplasty, and 84 underwent canal wall down mastoidectomy with tympanoplasty. After surgery, the average air conduction (AC) hearing threshold improved significantly, from 125 to 1000 Hz, but the average high-frequency AC and bone conduction (BC) hearing thresholds deteriorated significantly. In 21 (11%) cases, the BC hearing threshold worsened by more than 15 dB at 4000 Hz. When we compared these 21 cases to patients in whom hearing was preserved, the former group was found to be significantly younger and had a higher frequency of cholesteatomatous otitis media. However, when comparing the severity of inflammation in patients with temporal bone computed tomography, there was no significant difference between the 2 groups. Conclusions: High-frequency SNHL may develop after surgery to treat COM, especially in young patients with cholesteatoma.

Pure Tones

Quiet and masked thresholds were obtained from 5 subjects with normal hearing and 31 subjects with sensorineural hearing loss. Maskers were pure tones varying in frequency and intensity. The hearing-impaired subjects showed an abnormal spread of masking when masking was measured in terms of masked threshold. The abnormal spread of masking seems to be related to both the hearing threshold of the masker and the quiet threshold of the test signal. The notch due to detection of combination tones found on the high-frequency slope of masked audiograms of normal subjects (obscuring the actual extent to which the signal is masked) tends to accentuate the apparent abnormal upward spread of masking in the hearing-impaired subjects. The abnormal spread in the latter case is real, but comparison with the normal case must take the notch into account.

A Prospective Study

Objective Saccule could be damaged in patients with idiopathic sudden sensorineural hearing loss (ISSHL) with vertigo and with high-frequency sensorineural hearing loss. Thus, the saccule might be deteriorated subclinically in ISSHL cases without vertigo. Therefore, we investigated saccular damage in ISSHL patients without vertigo through vestibular evoked myogenic potentials (VEMP). Study Design A prospective study. Subjects and Methods Fifty-two patients with ISSHL without vertigo were enrolled in the study. We identified VEMP in patients with ISSHL and analyzed the association of VEMP with initial hearing threshold, each threshold according to frequency, the type of audiogram, and hearing recovery. Results For cases with absent VEMP, we found significant differences between patients with 90 dB or more hearing loss and those with a hearing loss less than 55 dB with frequencies over 1000 Hz. Patients with profound hearing loss presented significantly high abnormal and absent VEMP than patients with audiograms of other types. Conclusion These findings suggest that the subclinical deterioration of the saccular neuroepithelium is associated with patients with ISSHL having profound hearing loss at the high frequency.

INTRODUCTION Cochlear damage secondary to exposure to acoustic trauma is the consequence of the acoustic energy effects on the hearing cells in Korti's organ. OBJECTIVE The objective was to assess the correlation between the degree of sensorineural hearing loss and the type of audiogram registered in acoustic trauma exposed patients. METHOD We analyzed 262 audiograms of patients exposed to acoustic trauma in correlation to 146 audiograms of patients with cochlear damage and hearing loss not related to acoustic trauma. "A" group consisted of acoustic trauma cases, while "B" group incorporated cases with hearing loss secondary to cochlear ischaemia or degeneration. All audiograms were subdivided with regard to the mean hearing loss into three groups: mild (21-40 dB HL), moderate (41-60 dB HL) and severe (over 60 dB HL) hearing loss. Based on audiogram configuration five types of audiogram were defined: type 1 flat; type 2 hearing threshold slope at 2 kHz, type 3 hearing threshold slope at 4 kHz; type 4 hearing threshold notch at 2 kHz; type 5 notch at 4 kHz. RESULTS Mild hearing loss was recorded in 163 (62.2%) ears in the acoustic trauma group, while in 78 (29.8%) ears we established moderate hearing loss with the maximum threshold shift at frequencies ranging from 4 kHz to 8 kHz. The least frequent was profound hearing loss, obtained in 21 (8%) audiograms in the acoustic trauma group. Characteristic audiogram configurations in the acoustic trauma patient group were: type 1 (N=66; 25.2%), type 2 (N=71; 27.1%), and type 3 (N=68; 25.9%). Audiogram configurations were significanly different in the acoustic trauma group in comparison to the cochlear ischaemia group of patients (p=0.0005). CONCLUSION Cochlear damage concomitant to acoustic trauma could be assessed by the audiogram configuration. Preserved hearing acuity at low and mild frequency range indicates the limited damage to the hearing cells in Korti's organ in the apical cochlear turn.

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.
