OBJECTIVES/HYPOTHESIS To explore the possible determinants of bilateral audiometric notches in noise-induced hearing loss (NIHL). STUDY DESIGN Prospectively enrolled cohort with cross-sectional analysis. METHODS Male workers (n = 412) with exposure to continuous loud noise (noise exposure level normalized to a nominal 8-hour working day >75 dBA) during work were included in this cohort stud...

Audiometric records of 213 employees with low noise exposure were selected from the public domain data base underpinning Draft American National Standards Institute (ANSI) S12.13-1991 Standard Evaluating the Effectiveness of Hearing Conservation Programs. Records were selected from an ANSI S12.13 "control" group demonstrating raw audiometric thresholds in 1-dB steps, presumably resulting from s...

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...

INTRODUCTION  The implementation of hearing screening programs can be facilitated by reducing operating costs, including the cost of equipment. The Telessaúde (TS) audiometer is a low-cost, software-based, and easy-to-use piece of equipment for conducting audiometric screening. AIM  To evaluate the TS audiometer for conducting audiometric screening. METHODS  A prospective randomized study w...

Aim: To demonstrate the effect of laser therapy in the treatment of tinnitus with changes in audiometric results. Method: This current study included a total of 30 patients (15 females and 15 males). A laser with a 650 nm wave length at 5 mW was applied to the ear with tinnitus complaint on every consecutive week day for 20 minutes with a break on weekends. The process was continued for 8 weeks...

OBJECTIVE To further examine the reliability of categorical loudness scaling (CLS) for individual loudness categories and for the slope of the CLS functions. And, to evaluate the relationship between CLS and audiometric threshold. DESIGN CLS functions were obtained in 74 subjects, 58 with hearing loss and 16 with normal hearing. CLS functions were measured at three frequencies (1, 2, and 4 kH...

Recent studies suggest that the amplification needs of children and adults differ due to differences in perceptual ability. For example, several studies have confirmed that children realize greater benefit from a more audible speech signal (Stelmachowicz, Hoover, Lewis, Kortekaas and Pittman 2000; Stelmachowicz, Pittman, Hoover, Lewis and Moeller 2004), a higher signal-to-noise ratio (Hall and ...

OBJECTIVE To study the long-term results (use, care, satisfaction, ear infections, and audiometry) of the application of a bone-anchored hearing aid (BAHA) to patients with conventional indications who had previously used air-conduction hearing aids. DESIGN Follow-up study (mean duration, 9 years). SETTING Tertiary referral center. PATIENTS The study population comprised 27 patients with ...

Speech audiometric scores were compared across the age range from 50 to 90 years in 137 subjects selected in such a way that average audiometric thresholds were matched across four age groups. Thus any age-related changes in speech audiometric scores could not be attributed to age-related differences in peripheral hearing sensitivity. Four speech audiometric measures were studied; phonemically-...
