Pollution you hear
- Not all pollution is a chemical.
- Noise pollution 噪声污染 is unwanted, harmful sound.
- Traffic, aircraft, machines, and industry all add to it.
- It is loudest and most constant in busy cities.
你能听见的污染
- 不是所有污染都是化学物质。
- 噪声污染(noise pollution)是不需要的、有害的声音。
- 交通、飞机、机器和工业都增加它。
- 它在繁忙的城市里最响也最持续。
Measuring loudness
- Sound level is measured in decibels 分贝 (dB).
- A quiet room is about 30 dB; a busy street about 80 dB.
- A jet taking off is over 120 dB — painfully loud.
- The higher the number, the more damaging the sound.
衡量响度
- 声级以分贝(decibels,dB)衡量。
- 安静的房间约30分贝;繁忙的街道约80分贝。
- 一架起飞的喷气机超过120分贝——响得痛苦。
- 数字越高,声音越有害。
Noise pollution is… · 噪声污染是……
Noise pollution is unwanted, harmful sound — from traffic, machines, aircraft, and more. · 噪声污染是不需要的、有害的声音——来自交通、机器、飞机等。
Harm to people
- Years of loud noise cause permanent hearing 听力 loss.
- Constant noise raises stress and blood pressure.
- It disturbs sleep, leaving people tired and unwell.
- It makes it hard to think, learn, and rest.
对人的伤害
- 多年的响声造成永久性的听力(hearing)损失。
- 持续的噪声升高压力和血压。
- 它扰乱睡眠,让人疲倦和不适。
- 它让人难以思考、学习和休息。
Source or effect of noise pollution? · 噪声污染的来源还是影响?
Sort each item into a source of noise or an effect it causes. · 把每一项归入噪声的来源或它造成的影响。
Loudness of sound is measured in… · 声音的响度以以下单位衡量……
Sound level is measured in decibels (dB) — the higher the number, the louder and more damaging. · 声级以分贝(dB)衡量——数字越高,越响也越有害。
Years of loud noise can cause permanent ____ loss. · 多年的响声能造成永久性的____损失。
Long exposure to loud noise damages the ear, causing permanent hearing loss. · 长期暴露于响声损害耳朵,造成永久性的听力损失。
Harm to wildlife
- Animals rely on sound to communicate and navigate.
- Ship engines and sonar drown out whale 鲸 calls.
- Traffic noise scares birds away from good habitat.
- So noise harms nature as well as people.
对野生动物的伤害
- 动物依靠声音交流和导航。
- 船的引擎和声呐淹没鲸(whale)的叫声。
- 交通噪声把鸟从好的栖息地吓走。
- 所以噪声既伤害自然也伤害人。
Noise pollution can harm wildlife, such as whales that rely on sound to communicate. · 噪声污染能伤害野生动物,比如依靠声音交流的鲸。
Ship and sonar noise drowns out the sounds whales use to navigate and find each other. · 船和声呐的噪声淹没鲸用来导航和找到彼此的声音。
Select all · 所有 effects of noise pollution. · 选出噪声污染的所有影响。
Noise causes hearing loss, stress, and poor sleep. It has nothing to do with air quality. · 噪声造成听力损失、压力和差的睡眠。它与空气质量无关。
Noise pollution is easy to overlook because it leaves no residue — switch off the source and the noise is gone. But its effects are real and lasting: hearing loss doesn't reverse, and chronic noise raises stress and blood pressure for years. And it isn't only a human problem — underwater noise can disrupt whales across whole ocean basins.
噪声污染容易被忽视,因为它不留残留物——关掉来源,噪声就没了。但它的影响是真实且持久的:听力损失不可逆转,而慢性噪声多年升高压力和血压。而且它不只是人类的问题——水下噪声能扰乱整个海洋盆地的鲸。
Living near an airport:
- Every few minutes a jet roars overhead at over 100 decibels.
- The family's sleep is broken night after night, raising their stress and blood pressure.
- Over years, the constant noise dulls their hearing — a permanent harm from a pollutant that left nothing behind but sound.
住在机场附近:
- 每隔几分钟一架喷气机以超过100分贝在头顶轰鸣。
- 这家人的睡眠夜复一夜地被打断,升高他们的压力和血压。
- 多年之后,持续的噪声使他们的听力变钝——一种除了声音什么都不留下的污染物造成的永久伤害。
Noise pollution is unwanted, harmful sound, measured in decibels, from traffic, aircraft, and machines. In people it causes permanent hearing loss, stress, high blood pressure, and disturbed sleep. It also harms wildlife — for example, ship noise drowns out whale communication. Its effects last even though it leaves no residue.
噪声污染是不需要的、有害的声音,以分贝衡量,来自交通、飞机和机器。在人身上它造成永久性的听力损失、压力、高血压和被扰乱的睡眠。它还伤害野生动物——比如,船的噪声淹没鲸的交流。它的影响持续存在,尽管它不留残留物。
