OBJECTIVE To evaluate the role of otoacoustic emissions (OAEs) in the prediction of idiopathic sudden sensorineural hearing loss (ISSNHL) outcome. STUDY DESIGN Open-label prospective study. SETTING Tertiary referral medical center. PATIENTS Fifteen ISSNHL patients (age: 57.6 ± 16.2 years) were prospectively followed 7 days, 14 days, and 3 months post-presentation and the commencement of t...

In this paper, a physical and a perceptual evaluation of two adaptive noise reduction algorithms for digital hearing aids is described. This is the rst comparison between a xed microphone pattern, an adaptive directionalmicrophone and an adaptive beamformer,which are implemented in the same hearing aid.

This study aimed to evaluate audiological and vestibular involvement in Fabry disease and the effects of enzyme replacement therapy with human α-galactosidase A. The study population comprised 20 patients (11 males, 9 females) aged 15-69 years (mean 39.7). Patients underwent a complete clinical and instrumental evaluation before starting and during enzyme replacement therapy. median follow-up w...

INTRODUCTION It was proposed to ascertain the occurrence of individuals who present hearing loss, due to contracting meningitis, as well as to characterize the diagnosed loss as far as the type, degree and the audiometric configuration are concerned. MATERIAL AND METHOD The methodology used comprised a survey of 949 references of patients attended at the Hearing Disturbance Center of the HPRL...

Since its inception, Audiology has been concerned with hearing aid selection and the interaction of the hearing impaired person and amplification . The classic work of Watson and Knudsen (1) and Lybarger (2) suggests a long clinical interest in prescribing parameters for hearing aids according to audiometric measurements . In the early days, prescriptive procedures were neglected due to technol...

This case illustrates the occurrence of a sudden hearing sensitivity loss that, in all likelihood, was the result of brainstem disorder resulting from multiple sclerosis (MS) . Subject LD is a young woman who developed a sudden hearing loss while hospitalized for exacerbation of symptoms related to multiple sclerosis. By her own report, she had normal hearing in her left ear at the time of hosp...

It is well known that communication in noisy environments with reverberation present is a difficult problem to solve, particularly for the hearing-impaired listener. Two-microphone noise cancelling using an LMS adaptive filter in real time was used to process speech recorded in the presence of speech-spectrum noise at six different signal-to-noise ratios, -8, -4, 0, 4, 8, and 12 dB. Twelve norm...

Persons with impaired hearing who are candidates for amplification are not all equally successful with hearing aids in daily living. Having the ability to predict success with amplification in everyday life from measures that can be obtained during an initial evaluation of the patient's candidacy would result in greater patient satisfaction with hearing aids and more efficient use of clinical r...

OBJECTIVES This study aims to evaluate the communication problems of elderly before and after using hearing aids. PATIENTS AND METHODS Thirty hearing aid users and 10 normal hearing control subjects with their relatives were enrolled in the study. Hearing aid users were divided into three subgroups based on the duration of use. Self Assessment of Communication (SAC) and Significant Other Asse...

This paper describes the simple method of post processing for hearing impaired integrate into standard digital audio decoder such as AAC, AC3 or other codecs based on time/frequency transform. The results of evaluation, employing emulated hearing impairment, will be shown.
