From blaring car horns to wedding parties, rising noise pollution in the 24-hour metropolis of Cairo has reached alarming levels, leading to hearing problems, irritability and even death.
Living in the city center, where noise levels reach an average of 90 decibels (dB) and never drop below 70dB, is like spending all day inside a factory, a study by the Egyptian National Research Center (NRC) last year said.
"What's striking about Cairo is that noise levels on different streets at different times of day are well over limits set by the environmental protection agency [EPA]," the NRC's Mustafa Ali Shafiye said.

"In downtown, noise levels may attain 90dB at 7:30am, bearing in mind that the normally acceptable level set by the EPA is 35-55 dB," he said.
In December, the respected New Scientist magazine said that "noise kills in much the same way as chronic stress does."
It causes "an accumulation of stress hormones, inflammation and changes in body chemistry that eventually lead to problems such as impaired blood circulation and heart attacks," the magazine said.
Mohammed el-Shazly, an ear specialist at Cairo University, said: "The noise in Cairo is exceptional -- it cannot be compared to any other Arab city."
"What is special about Cairo is that industrial zones and residential areas are not separated. People like policemen who are permanently on the street can be severely affected," he said.
People start to lose their hearing gradually, he said, and once that happens the only cure is to get a hearing aid.
"Car horns, loud music, shouting, aging engines and the occasional party can lead to a series of health problems including hypertension, hearing loss, cardiovascular effects and general irritability" said Nagat Amer, an environmental health specialist at the NRC.
"Noise severely affects pregnant women who are permanently exposed to it. It causes retraction in blood vessels and they give birth to small babies," she said.
"The cost of this is enormous: We can count non-concentration at work, absenteeism, accidents, handicaps," she said. "Protecting ourselves from noise is much less expensive than what it may cost later."
The WHO, which considers noise pollution to be the world's third-worst after polluted air and water, has said that exposure for more than eight hours a day to sound in excess of 85db is potentially hazardous.
The ministries of health and environment are planning to establish a national network for monitoring noise levels in Egypt, but no date has yet been fixed for it to begin gathering data.
A 1994 law laying down legal ambient noise limits is largely ignored. Under this law, levels should not exceed 52db during the day, 37db at night and a very loud 90db in industrial areas such as factories.
With Cairo's population continually expanding and no official solution within earshot, tens of thousands of people are fleeing to quieter and less-polluted suburbs.
"I used to hear car horns, shops opening and closing, people shouting," said Dina Kozman, a housewife who left the city center three years ago for a residential compound. "Traffic makes noise and noise makes stress. It's a vicious circle."
PHISHING: The con might appear convincing, as the scam e-mails can coincide with genuine messages from Apple saying you have run out of storage For a while you have been getting messages from Apple saying “your iCloud storage is full.” They say you have exceeded your storage plan, so documents are no longer being backed up, and photos you take are not being uploaded. You have been resisting Apple’s efforts to get you to pay a minimum of £0.99 (US$1.33) a month for more storage, but it seems that you cannot keep putting off the inevitable: You have received an e-mail which says your iCloud account has been blocked, and your photos and videos would be deleted very soon.

For two decades, researchers observed members of the Ngogo chimpanzee group of Kibale National Park in Uganda spend their days eating fruits and leaves, resting, traveling and grooming in their tropical rainforest abode, but this stable community then fractured and descended into years of deadly violence. The researchers are now describing the first clearly documented example of a group of wild chimpanzees splitting into two separate factions, with one launching a series of coordinated attacks against the other. Adult males and infants were targeted, with 28 deaths. “Biting, pounding the victim with their hands, dragging them, kicking them — mostly adult males,
The Israeli military has demolished entire villages as part of its invasion of south Lebanon, rigging homes with explosives and razing them to the ground in massive remote detonations. The Guardian reviewed three videos posted by the Israeli military and on social media, which showed Israel carrying out mass detonations in the villages of Taybeh, Naqoura and Deir Seryan along the Israel-Lebanon border. Lebanese media has reported more mass detonations in other border villages, but satellite imagery was not readily available to verify these claims. The demolitions came after Israeli Minister of Defense Israel Katz called for the destruction of
SUPERFAN: The Japanese PM played keyboard in a Deep Purple tribute band in middle school and then switched to drums at university, she told the British rock band Legendary British rock band Deep Purple yesterday made Japanese Prime Minister Sanae Takaichi’s day with a brief visit to their high-profile superfan as they returned to the nation they first toured more than half a century ago. Takaichi’s reputation as an amateur drummer, and a fan of hard rock and heavy metal has been well documented, and she has referred to Deep Purple as one of her favorite bands along with the likes of Black Sabbath and Iron Maiden. “You are my god,” a giddy Takaichi said in English to Deep Purple drummer Ian Paice, presenting him with a set of made-in-Japan
