Now days Because of menatal stress lack of physical exercise and lack of time due work  most of the people affect of many kinds of disorders   because of this we have to need regular exercise  and yoga  to overcome this and be healthy by physicaly and mentaly Yoga offers numerous benefits for both the mind and body. Here are some of the key benefits of practicing yoga: Physical Fitness:  Yoga improves strength, flexibility, balance, and stamina. It helps tone the muscles and increases overall physical fitness. Regular practice can lead to improved posture and alignment. Stress Reduction:  Yoga incorporates breathing exercises and meditation, which can help calm the mind and reduce stress levels. It promotes relaxation and provides a sense of inner peace. Mental Clarity:  The combination of physical movement, breath control, and mindfulness in yoga can enhance mental clarity, focus, and concentration. It can also improve memory and cogni...

NOISE INDUCE HEARING LOSS INTRODUCTION Noise induce hearing loss is the 2nd most common cause of hearing loss , most  common being presbycusis millions of individuals worldwide suffered from  NIHL • Noise-induced hearing loss (NIHL) is a hearing impairment resulting from  exposure to loud sound. People may have a loss of perception of a narrow  range of frequencies or impaired perception of sound including sensitivity to  sound or ringing in the ears . When exposure to hazards such as noise occur  at work and is associated with hearing loss, it is referred to as occupational  hearing loss Hearing may deteriorate gradually from chronic and  repeated noise exposure (such as to loud music or background  noise) or suddenly from exposure to impulse noise, which is a  short high intensity noise (such as a gunshot or airhorn).In  both types, loud sound overstimulates delicate hearing cells,  leading to the permanent injury or death of...

The sound signal that reach to the ear drum in the form of air vibration must be transmitted to the cochlea which is a fluid filled system'  The impedance of cochlear fluids are much greater then the impedance of air: Most of the sound energy reflected back  only about 0.1% of the energy transmitted to the cochlea and 99.9% if the energy is reflected back The middle ear overcome this impedance mismatch by acting as a mechanical transformer that boost the signal so that energy can be effectively transmitted to the cochlea There are three mechanism which are used to overcome the transformer action of middle ear 1-Area ratio of Ear drum to Oval window 2-Curved membrane buckling effect of the tympanic membrane 3- Lever action of the ossicular chain 1. The Ratio of Ear drum to Oval window The largest contributions comes from Area advantages' The Area of tympanic membrane larger than the Area of Oval window , The force that us exerted over the larger area of tympanic membrane i...
