Hearing Loss and MP3 Essay Example
Hearing Loss and MP3 Essay Example Hearing Loss and MP3 Paper Hearing Loss and MP3 Paper Cochlea is a snail like-structure located at the inner ear. Canals which transmits pressure and The organ of corti the sensitive part which detects pressure impulses, that travels along the auditory nerve that absorbs electrical impulses from the cochlea. Semicircular canals that balance body organs and detects acceleration of three perpendicular planes which helps you keep your balance. Auditory hair cells are vital part of the earââ¬â¢s to detect easily the sound it has microscopic hair-like projections which consist of channel or pores that openà after the hair like projections are subjected to mechanical force. Channel opens and releases small molecules in a chemical reaction that directly tells the brain that the sound has been detected . Hearing disability can be in all age groups. Children because of infection due developmental stage of the fetus can genetically acquire hearing loss. It includes congenital syndrome such as Down Syndrome or Trisomy 21, Parent with familial deafness can be genetically acquired, infections during pregnancy of the mother for example the mother had German measles (rubella)à or cytomegalovirusà during high risk of pregnancy. With superficial hearing loss can have dilemmaà à in speech development andà à learning. In adults, most common cause of hearing loss are caused by progressive bilateral hearing loss or senile deafness and noise that can be made by men. ââ¬Å"old hearingâ⬠à which affects men rather than woman, it also linked to noise exposure, most of this are men who are working in industrialized company orà military men whose in the field. Mechanism of hearing is complicated. Sound waves which enters the ear canal and moves freely in the eardrum we called it tympanic membrane; eardrum is located to the hearing organ or cochlea with small bones called ossicles which anchored to the eardrum. Cochlea also called oval window, movement of the eardrum that sets up movements in the bones which in return the oval window, these tiny hair cells that lines the part of the cochlea are stimulated by these waves, which transmitsà nerve impulses that travels along the brain which can detect if the sound is received. Nowadays MP3 is a cultural phenomenon and it is a matter of fact that millions of electronic devices and computers includes and supports MP3 capacity. In the 21st century MP3 has caused a new shift in developing electronic devices and thus has captured attention of millions people worldwide. MP3 is a standard for audio compression meaning that this standard aims at making any music file smaller and loss of sound quality is little. Actually, MP3 is a part of MPEG characterized by low bandwidth. Millions of music lovers are re-awakened because MP3 gives them an excellent opportunity to store thousands of songs, to search them by genre, artists and title. Thee whole music collection is available when clicking simply one button. Therefore, MP3 is more than a technology. Jones (2000) stated that MP3 is sensational development. Nevertheless, controversies over health risk are present as well as MP3 is stated to entail potential health risk. Jones (2000) cited The Institute of Hearing Research who admitted admitted that ââ¬Å"new technology and ever-increasing storage capacity enables people to listen non-stop for hours and at louder volumes than ever before which could eventually impair hearingâ⬠. Thus, MP 3 may cause ringing or buzzing in ears. Andrew Reid, the British Society of Audiology, says (Jones 2000) that ââ¬Å"if people experience that they really need to turn down the player straight away and then consult their doctor if the problems persistâ⬠. He comments (Jones 2000) that ââ¬Å"this evidence suggests that people should get better quality headphones if they want to safeguard their hearingâ⬠meaning that MP3 may cause users to crank up music to the highest and the most dangerous levels. Prevent Hearing Loss 2006) says: ââ¬Å"If you keep the volume at a level where you can still comfortably carry on a conversation, you wonââ¬â¢t need to limit the amount of time you listen to your musicâ⬠.à Thus, the volume should never be turned all the way up. Actually, the noise is considered safer if a person going next to you doesnââ¬â¢t hear your music and if he hears it means that the music is dangerously loud. So, Spencer (2006) recommended being aware of the music style and noise. To prevent hearing loss doctors strongly recommend giving ears necessary rest not depending on music volume because quieter noise continuing for long period of time is more harmful than highly-intensive noise for a short time period. Summing up, the best preventive strategies are to buy earphones with the highest quality, to limit music volume and time of exposure and, finally, to allow ear to take a rest to recover from noise.
