    the basilar membrane in the inner ear and tiny bundles of hair, each finely tuned to detect sounds at different frequencies, transmit the vibrations to the brain for decoding. The inner ear responds to these just like any other vibrations, turning them into electrical signals and sending them to the brain. Whenever we speak, our inner ear is stimulated by internal vibrations in our bones and the sound coming out of our mouth traveling through the air into the ears. Hence it's a combination of these

  • Sensorineural Hearing Loss Case Study

    810 Words  | 4 Pages

    1. Introduction Sensorineural hearing loss (SNHL) is a type of deafness which is often caused by the damage on hair cells of cochlea in inner ears. Hair cells convert acoustic sounds to electrical signals and stimulate auditory nerves. The clinical treatment for the hearing loss in both children and adults is by using the artificial cochlea. This device bypasses the damaged hair cells by generating the electric current in response to acoustic sound. Current artificial cochlea consist of an implantable

    sound is the best way to set about reducing it. Sound is an energy that 's produced when things vibrate. This energy travels outward, making objects and the air all around us vibrate in sympathy until what 's left of the energy reaches our ears. Inside our ears, the air vibrates too, stimulating tiny hair cells deep inside our heads, and registering the sounds in our brains. If you want to stop it in its tracks you have to interrupt that chain of events somewhere along the route. Understanding how
