A review of the problems of noise induced hearing loss in children, especially related to recreational music and the use of personal entertainment devices. The patho-physiology of noise induced hearing loss, and associated problems (e.g. tinnitus) are discussed. The evidence for an increase in noise induced hearing loss in children and young people is reviewed. Some practical advice (for clinic...

Background and Aim: Exposure to impact noise (short-term, high intensity) higher than permitted levels results in injury to the auditory system. Armed forces are one of the occupational groups exposed to these types of noises resulting from gunshots. In this study, relevant articles and research on the adverse effects of impact noise, hearing loss, and tinnitus in armed forces and effective con...

Introduction: Noise is one of the most common and harmful physical factors in the working environment and has physical and psychological effects on individuals. In this study, the audiometry results of industrial workers were modeled and the effect of noise and other factors on hearing loss was examined.   Materials and Methods:                                                 ...

Hearing tests: quantify the hearing abilities of people with both normal hearing and hearing impairments Speech reception threshold (SRT): SNR level at which the speech recognition rate of a person is 50% – Evaluating a listener’s hearing capabilities and diagnosing hearing loss – Adjusting the CI parameters and analyze the impact of new developments in CI devices – Provides useful data for psy...

The international scientific literature reports no data on the prevalence and effectiveness of back protector devices (BPD). In Italy, no data have been collected on BPD because their use is not mandatory. To fill this gap, the National Institute of Health implemented a cross-sectional study in collaboration with the National Traffic Police.Accident cases were collected from 1 December 2011 to ...

improvements in science and technology and the use of modern machinery in manufacture have led to increase in the number of workers exposed to hazardous agents including noise. this study evaluated the effects of occupational noise on hearing loss and blood pressure in welders after 4 years.in this cohort study, all of the welders working at one of neyshabur's water heater producing factories w...

Advances in technology and expanding candidacy guidelines have motivated many clinics to consider children with precipitously sloping high-frequency hearing loss as candidates for cochlear implants (CIs). A case study is presented of a pediatric CI patient whose hearing thresholds were preserved within 10 dB of preimplant levels (125-750 Hz) after receiving a fully inserted 31.5-mm electrode ar...

The improvement of speech intelligibility in hearing aids is a traditional problem that still remains open and unsolved. Modern devices may include signal processing algorithms to improve intelligibility: automatic gain control, automatic environmental classification or speech enhancement. However, the design of such algorithms is strongly restricted by some engineering constraints caused by th...
