People who hear a constant humming might be experiencing tinnitus, a condition that requires medical treatment, a doctor said.
Taichung’s Kuang Tien General Hospital Ear Nose and Throat Department chair Lai Jen-tsung (賴仁淙) cited the case of one of his patients, Siao Ling (小玲), a 59-year-old retired teacher from Chiayi, who spent a considerable amount of money on ineffective traditional remedies before going to the hospital.
Siao Ling said she started experiencing tinnitus symptoms during a hiking trip three years ago. The humming started when she was descending a mountain.
The condition has severely affected her quality of life, she said.
Unable to engage in her hobbies, she said tinnitus drove her to depression. She saw a qigong master who said she was hearing things because her ears were being attacked by “137 ghosts” and their negative energy.
After the treatments were ineffective, a friend convinced her to seek medical help, she said.
Lai said that tinnitus is a medical condition with a variety of causes and is triggered when problems arise in any of the brain’s three neurological systems governing sleep, emotions and autonomic functions, which are intimately tied to the functions of the cerebrum and auditory pathways.
Common causes for tinnitus include hearing damage, viral infections, Meniere’s disease, acoustic neuroma and aging, as well as Eustachian tube blockage, sleep disorders and autonomic dysfunctions, Lai said.
Hearing tests are a standard part of tinnitus diagnosis and treatment, because about eight out of 10 people with tinnitus have undiagnosed hearing loss that they were not aware of, and an accurate tinnitus diagnosis includes hearing tests, Lai said.
About 70 percent of tinnitus sufferers develop insomnia and other sleep disorders. Sleep deprivation puts stress on the body, including the auditory system, which can exacerbate tinnitus, causing a vicious cycle in which the condition becomes increasingly more severe, he said.
Lai said he used tinnitus retraining therapy in combination with hormone therapy to treat Siao Ling.
Tinnitus retraining therapy introduces patients to discontinuous noises, such as the sound of water droplets or a waterfall, which alleviates tinnitus by modifying conditioned responses, assisting the brain to develop a habit of automatically filtering and ignoring tinnitus, he said.
A magnitude 6.4 earthquake struck off the coast of Hualien County in eastern Taiwan at 7pm yesterday, the Central Weather Administration (CWA) said. The epicenter of the temblor was at sea, about 69.9km south of Hualien County Hall, at a depth of 30.9km, it said. There were no immediate reports of damage resulting from the quake. The earthquake’s intensity, which gauges the actual effect of a temblor, was highest in Taitung County’s Changbin Township (長濱), where it measured 5 on Taiwan’s seven-tier intensity scale. The quake also measured an intensity of 4 in Hualien, Nantou, Chiayi, Yunlin, Changhua and Miaoli counties, as well as
Taiwan is to have nine extended holidays next year, led by a nine-day Lunar New Year break, the Cabinet announced yesterday. The nine-day Lunar New Year holiday next year matches the length of this year’s holiday, which featured six extended holidays. The increase in extended holidays is due to the Act on the Implementation of Commemorative and Festival Holidays (紀念日及節日實施條例), which was passed early last month with support from the opposition Chinese Nationalist Party (KMT) and Taiwan People’s Party. Under the new act, the day before Lunar New Year’s Eve is also a national holiday, and Labor Day would no longer be limited
COMMITMENTS: The company had a relatively low renewable ratio at 56 percent and did not have any goal to achieve 100 percent renewable energy, the report said Pegatron Corp ranked the lowest among five major final assembly suppliers in progressing toward Apple Inc’s commitment to be 100 percent carbon neutral by 2030, a Greenpeace East Asia report said yesterday. While Apple has set the goal of using 100 percent renewable energy across its entire business, supply chain and product lifecycle by 2030, carbon emissions from electronics manufacturing are rising globally due to increased energy consumption, it said. Given that carbon emissions from its supply chain accounted for more than half of its total emissions last year, Greenpeace East Asia evaluated the green transition performance of Apple’s five largest final
The first tropical storm of the year in the western North Pacific, Wutip (蝴蝶), has formed over the South China Sea and is expected to move toward Hainan Island off southern China, the Central Weather Administration (CWA) said today. The agency said a tropical depression over waters near the Paracel and Zhongsha islands strengthened into a tropical storm this morning. The storm had maximum sustained winds near its center of 64.8kph, with peak gusts reaching 90kph, it said. Winds at Beaufort scale level 7 — ranging from 50kph to 61.5kph — extended up to 80km from the center, it added. Forecaster Kuan Hsin-ping
