＜p＞This book describes the Lows and Highs of Hearing Disorders, Diagnosis and Treatment and Related Diseases＜/p＞ ＜p＞Hearing is one of the most important human senses.＜/p＞ ＜p＞People use the hearing to take in the information around them and learn from their experiences.＜/p＞ ＜p＞To go through life without hearing is not easy but possible (especially with use of sign language).＜/p＞ ＜p＞Hearing refers to the ability to perceive noise and sounds.＜/p＞ ＜p＞The hearing is used to listen to music, talk to people around the person and assess social and environmental situations.＜/p＞ ＜p＞The sounds the person hears each day serve to make the life richer.＜/p＞ ＜p＞Birds chirping, a child laughing or the favorite song have sound value that is intangible, but still shapes the everyday life in manners that people often take for granted.＜/p＞ ＜p＞The hearing is also a teaching instrument, warning people of possible danger and permitting people to pick up on social cues.＜/p＞ ＜p＞The sound of fire alarms, a telephone ringing or a car horn can all be very important in a dangerous situation.＜/p＞ ＜p＞The Lows of Hearing: Hearing Loss＜/p＞ ＜p＞There are 2 main forms of hearing loss.＜/p＞ ＜ol＞ ＜li＞Conductive hearing loss - this happens when there is a problem in the transmission of sound waves from the external ear, through the middle ear.＜/li＞ ＜/ol＞ ＜p＞The disease processes can happen at any level along this part of the ear.＜/p＞ ＜p＞Conductive hearing loss (CHL) happens due to a mechanical problem in the outer or middle ear.＜/p＞ ＜p＞This may be because:＜br /＞ a. The three tiny bones of the ear (ossicles) are not conducting sound properly.＜br /＞ Otosclerosis＜br /＞ Prebysacusis＜br /＞ Otitis Media＜br /＞ b. The eardrum is not vibrating in reaction to sound.＜br /＞ Eardrum perforation＜br /＞ Wax in ear canal＜/p＞ ＜ol start="2"＞ ＜li＞Sensorineural hearing loss (SSNHL) - this indicates problems happening in the cochlea (the most frequent site of disease), cochlear nerve or brain stem, leading to abnormal or absent neurosensory impulses.＜/li＞ ＜/ol＞ ＜p＞Sensorineural hearing loss is more frequent in adults.＜/p＞ ＜p＞Hearing loss can also be separated into categories to indicate the severity.＜/p＞ ＜p＞Mild hearing loss (20-40 dB HL): cannot hear whispers＜/p＞ ＜p＞Moderate hearing loss (41-70 dB HL): cannot hear conversational speech＜/p＞ ＜p＞Severe hearing loss (71-95 dB HL): cannot hear shouting, need a hearing aid＜/p＞ ＜p＞Profound hearing loss (95 dB HL or more): cannot hear sounds that would be painful to listen to for a hearing person＜/p＞ ＜p＞Hearing loss can be acquired (due to injury or infection) or a result of genetics and congenital disorders.＜/p＞ ＜p＞Hearing loss is treatable, but the sooner it is treated, the better.＜/p＞ ＜p＞Highs of Hearing: Hypersensitivity to Sound＜/p＞ ＜p＞Hypersensitivity to sound can be equally a symptom and a source of anxiety.＜/p＞ ＜p＞People talking, honking of car horns, clanking of pans, and printers printing can become quite a nuisance as each tiny noise is an added injury to the brain.＜/p＞ ＜p＞In dangerous situations, noise hypersensitivity may be advantageous.＜/p＞ ＜p＞Those that have felt trauma may also become more sensitive to sound.＜/p＞ ＜p＞Decreased sound tolerance follow tinnitus in 60% of patients＜/p＞ ＜p＞Hyperacusis is a collapsed tolerance to normal environmental sounds.＜/p＞ ＜p＞Misophonia (hatred of sound) is an adverse response to sound at any volume.＜/p＞ ＜p＞It is possible to achieve the cure for both hyperacusis and misophonia with tinnitus retraining therapy and sound desensitization.＜/p＞ ＜p＞The ability to hear is important to all healthy persons.＜/p＞ ＜p＞TABLE OF CONTENT＜br /＞ Introduction＜br /＞ Chapter 1 Hearing Disorders＜br /＞ Chapter 2 Hearing Loss (Deafness)＜br /＞ Chapter 3 Otosclerosis＜br /＞ Chapter 4 Prebyacusis＜br /＞ Chapter 5 Tinnitus (Updated)＜br /＞ Chapter 6 Hyperacusis (Updated)＜br /＞ Chapter 7 Misophonia (Updated)＜br /＞ Chapter 8 Meniere’s Disease (Updated)＜br /＞ Epilogue＜/p＞画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。
