Transcript:

Long term exposure to noise can lead to loss of hearing. The relative loudness of sounds is measured in decibels. Just to give you an idea of what this means. The sound of a whisper is thirty decibels, while a normal conversation is sixty decibels. The noise of vacuum cleaner makes is around eighty five decibels. The danger zone, the risk of injury begins it around ninety. Continual exposure to sounds above ninety decibels can damage your hearing loud noises, especially when they come at you every day. All this noise can damage the delicate hair cells in your inner ear. Lots of everyday noises are bad for us in the long run. For example, a car horn sounds at around one hundred decibels. A rock band at close range is one hundred and twenty five decibels. A jet engine at close range is one of the worst culprits at an ear busting one hundred and forty decibels. The first thing to go is your high frequency hearing, where you detect the consonant sounds in words.

* Click on the correct answer

Loss of hearing are caused by long-term exposure to noise. However, in everyday life, the average decibels lever is below 140 decibels, which has no negative effect on our hearing. Only jet engine at close range is the worst culprits at an ear. A conversation at close range as well as a rock band at close range could contribute to hearing loss. However, long term exposure to jet engineer made people get used to noise and wouldn’t cause hearing loss as rock band does. The danger zone of hearing loss are discussed, ranging from 30 decibels to 100 decibels. All this noise can damage the delicate hearing cells. As a result, a person with hearing loss can’t hear voice. Loss of hearing are caused by exposure to noise over a long window of time. At 90 decibels level, people have risk of hearing loss begin. Lots of everyday life can damage your hearing, for examples, long term exposure to rock bands and jet engines.

Option 4: "Loss of hearing are caused by exposure to noise over a long window of time. At 90 decibels level, people have risk of hearing loss begin. Lots of everyday life can damage your hearing, for examples, long term exposure to rock bands and jet engines."

Explanation: This option accurately summarizes the main idea of the text, which discusses how long-term exposure to noise can lead to hearing loss. It correctly identifies that the risk begins at 90 decibels and mentions everyday sources of harmful noise, such as rock bands and jet engines, aligning well with the text's content.

Option 1: "Loss of hearing are caused by long-term exposure to noise. However, in everyday life, the average decibels lever is below 140 decibels, which has no negative effect on our hearing. Only jet engine at close range is the worst culprits at an ear."

Explanation: This option incorrectly states that the average decibel level in everyday life is below 140 decibels and suggests that this has no negative effect on hearing. The text emphasizes that sounds above 90 decibels can damage hearing, contradicting the claim made here. Additionally, it misrepresents the jet engine as the only worst culprit, while the text lists multiple sources of harmful noise.

Option 2: "A conversation at close range as well as a rock band at close range could contribute to hearing loss. However, long term exposure to jet engineer made people get used to noise and wouldn’t cause hearing loss as rock band does."

Explanation: This option inaccurately implies that long-term exposure to jet engines does not cause hearing loss, which contradicts the text stating that continual exposure to sounds above 90 decibels can damage hearing. Furthermore, it incorrectly suggests that conversations and rock bands are equally harmful, while the text highlights the significant danger posed by louder noises.

Option 3: "The danger zone of hearing loss are discussed, ranging from 30 decibels to 100 decibels. All this noise can damage the delicate hearing cells. As a result, a person with hearing loss can’t hear voice."

Explanation: This option misrepresents the range of decibels discussed in the text. The text indicates that the risk of hearing loss begins at 90 decibels, not 30. Additionally, while it mentions damage to delicate hearing cells, it fails to capture the broader context of everyday noise exposure and the specific examples provided in the text.
