AIMS AND OBJECTIVES To identify and compare hearing protection interventions for youth working and living on farms. BACKGROUND Noise-induced hearing loss represents a significant risk factor for injury, disability and death in agricultural populations due to an inability to receive sensory information that can indicate dangerous situations. Despite the availability of hearing protection devic...

Previous studies have reported that modification of histones alters aminoglycoside-induced hair cell death and hearing loss. In this study, we investigated three FDA-approved histone deacetylase (HDAC) inhibitors (vorinostat/SAHA, belinostat, and panobinostat) as protectants against aminoglycoside-induced ototoxicity in murine cochlear explants and in vivo in both guinea pigs and CBA/J mice. In...

Hearing loss is a significant and unfortunately common occupational malady. Over the past several decades both the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) have initiated efforts to better understand and to limit the occurrence of occupational hearing loss, particularly as it relates to excessive noise exposure. T...

Sudden sensorineural hearing loss is characterized by acute, idiopathic hearing deterioration. We report here the development and evaluation of "constraint-induced sound therapy", which is based on a well-established neuro-rehabilitation approach, and which is characterized by the plugging of the intact ear ("constraint") and the simultaneous, extensive stimulation of the affected ear with musi...

introduction: sudden sensorineural hearing loss (ssnhl) has a prevalence of 10 in 100,000. viral infections, vascular obstruction and rupture of the intracochlear membranes are supposed to be its most common etiologies. about 40% of patients experience vertigo or imbalance. the vemp (vestibular evoked myogenic potentials) test is a known approach for detailed study of the labyrinth. the advanta...

introduction: hearing loss is one of the most common problems in elderly people. functional side effects of hearing loss are various. due to the fact that hearing loss is the common impairment in elderly people; the importance of its possible effects on auditory memory is undeniable. this study aims to focus on the hearing loss effects on auditory memory.   materials and methods: dichotic audit...

BACKGROUND Ultrasound images are usually affected by speckle noise, which is a type of random multiplicative noise. Thus, reducing speckle and improving image visual quality are vital to obtaining better diagnosis. METHOD In this paper, a novel noise reduction method for medical ultrasound images, called multiresolution generalized N dimension PCA (MR-GND-PCA), is presented. In this method, t...

The type of noise annoyance scale and aspects of its presentation such as response format or location within a questionnaire and other contextual factors may affect self-reported noise annoyance. By means of a balanced experimental design, the effect of type of annoyance question and corresponding scale (5-point verbal vs. 11-point numerical ICBEN (International Commission on Biological Effects...
