Exposure to high levels of noise will cause permanent hearing disorder. Neither surgery nor a hearing aid will facilitate correct this kind of hearing disorder. short exposure to clap may cause a brief modification in hearing (your ears could feel stuffed up) or a ringing in your ears (tinnitus). These short issues could get away inside some minutes or hours once going away the noise. However, recurrent exposures to clap will result in permanent symptom and/or hearing disorder.Loud noise will produce physical and psychological stress, cut back productivity, interfere with communication and concentration, and contribute to work accidents and injuries by creating it troublesome to listen to warning signals. the results of noise-induced hearing disorder are often profound, limiting your ability to listen to high-frequency sounds, perceive speech, and seriously impairing your ability to speak.When sound waves enter the external ear, the vibrations impact the ear drum and area unit transmitted to the center and receptor. within the cavum, 3 little bones referred to as the auditory ossicle (or hammer), the anvil (or anvil), and therefore the auditory ossicle (or stirrup) amplify and transmit the vibrations generated by the sound to the receptor. The receptor contains a snail-like structure referred to as tube-shaped structure that is full of fluid and lined with cells with terribly fine hairs. These microscopic hairs move with the vibrations and convert the sound waves into nerve impulses–the result’s the sounds we have a tendency to hear. Exposure to clap will destroy these hair cells and cause hearing loss!
Q. Which of the following statements about health can be supported by the text?
(A) Even after long exposure, the sound is unlikely to cause hearing loss.
(B) The cochlea is responsible for the transfer of sound waves into nerve impulses.
(C) Exposure to noise at work can harm worker’s health.
(D) Three small bones of outer ear – malleus, incus, and stapes are attached like a chain to the tympanic membrane and convert sound waves.
