Vent Configurations on Subjective and Objective Occlusion Effect

Vent configurations on subjective and objective occlusion effect.

The current study reexamined the effect of vent diameters on objective and subjective occlusion effect (OE) while minimizing two possible sources of variability. Nine hearing-impaired participants with primarily a high-frequency hearing loss were evaluated. Laser shell-making technology was used to make ear inserts of completely-in-the-canal (CIC) hearing aids for the study. This was to minimiz...

The Effect of Sleep Deprivation on Objective and Subjective Physiological Responses of Student-Athletes

Introduction: Sleep deprivation is one of the factors affecting the physiological performance of athletes and laboratory evidence has suggested a link between sleep deprivation and decreased physical performance of athletes. The aim of this study was to determine the effect of sleep deprivation on objective and subjective physiological responses of student-athletes. Material and Methods: The r...

Noise effect on fatigue: correlation between the subjective and objective indicators.

Introduction: Fatigue is the exhaustion of the body or spirit that can be caused by stress, excessive work, drug use, or physical or mental illness. Fatigue is a factor in reducing productivity and incidents. Therefore, measuring is important. The aim of this study was to determine the fatigue measurement measurements based on objective and objective indices. Materials and Methods: A cross-s...

Observations on the relations among occlusion effect, compliance, and vent size.

In a clinical experiment, it was found that there is a high correlation between the compliance measured by tympanometry and the minimum size of the earmold vent, which just solves the client's occlusion problem related to his/her own voice when using a hearing aid. For ears with sensorineural hearing losses, compliance explained 59 percent of the variation in vent size, whereas the average low-...
