Over 1 billion youngsters at hearing loss risk due to headphones, loud music: Study
Washington (PTI): Over one billion teenagers and young people are potentially at risk of hearing loss due to their use of headphones and earbuds, and attendance at loud music venues, according to a study published in the journal BMJ Global Health.
The international team, including researchers from Medical University of South Carolina, US, noted that the governments around the world need to urgently prioritise "safe listening" policies to safeguard aural health.
"There is an urgent need for governments, industry, and civil society to prioritise global hearing loss prevention by promoting safe listening practices," the authors of the study said.
The World Health Organization (WHO) estimates that over 430 million people worldwide currently have disabling hearing loss, the researchers said.
Young people are particularly vulnerable because of their use of personal listening devices (PLDs), such as smartphones, headphones and earbuds, and attendance at loud music venues, amid poor regulatory enforcement, they said.
Previously published research suggests that PLD users often choose volumes as high as 105 decibel (dB) while average sound levels at entertainment venues range from 104 to 112 dB.
This far exceeds the permissible sound levels of 80 dB for adults and 75 dB for children even if for very short periods of time.
The researchers gauged the prevalence of unsafe listening practices among teens and young adults to create a global estimate of the numbers who could therefore be at risk of hearing loss.
They trawled research databases for relevant studies published in English, French, Spanish and Russian, involving 12-34 year-olds, and reporting on objectively measured device output levels and length of exposure.
The research included 33 studies, corresponding to data from 35 records and 19,046 participants. 17 records focused on PLD use and 18 focused on loud entertainment venues.
The researchers also estimated the number of people who could be at risk of hearing loss by considering the estimated global population of 12-34 year-olds in 2022 (2.8 billion) and the best estimates of exposure to unsafe listening practices from PLDs or loud entertainment venues.
The research indicates that the prevalence of unsafe listening practices from PLD use and attendance at loud entertainment venues is common worldwide -- 24 per cent and 48 per cent, respectively, among teens and young people.
The researchers estimate that the global number of teens and young adults who could potentially be at risk of hearing loss as a result ranges from 0.67 to 1.35 billion.

Caste census decision may take a year: Karnataka Minister Satish Jarkiholi
Bengaluru, Apr 18 (PTI): Karnataka PWD Minister Satish Jarkiholi on Friday said a decision on the Social and Educational Survey report, popularly referred to as caste census, is unlikely in the near future and may take upto a year due to the complexities involved.
He also cautioned that any misstep in addressing the concerns raised by various castes over the report may cause problems for the ruling Congress party in the future.
His remarks came a day after a special cabinet meeting convened to deliberate on the caste census report ended without any concrete decision amid internal differences within the government.
The cabinet is scheduled to take up the matter again on May 2.
"It is not something that will happen tomorrow, it may take one year. Don't expect it tomorrow, it may take a year, because there are issues, they are complicated. If everyone has to be pacified and taken into confidence, many meetings have to be held, the government has to be in a compromise mode, because this cannot be done all of a sudden," Jarkiholi said in response to a question.
Addressing reporters here, he said the report was almost 10 years old and the cabinet had taken it for consideration more than a year after its submission in February 2024.
"Nothing to worry, if discussions go on for a year. There is no urgency... Taking everyone into confidence, with unanimity and with cooperation of everyone, we will try to implement it," he added.
According to sources, some Ministers expressed reservations about the survey report in the cabinet, citing concerns raised by several quarters calling it "unscientific and outdated", and about undercounting.
Following this Chief Minister Siddaramaiah asked all Ministers to offer their views in writing or verbally.
Various communities, especially Karnataka's two dominant ones -- Vokkaligas and Veershaiva-Lingayats -- have expressed strong reservations about the survey that has been done, calling it "unscientific", and have demanded that it be rejected, and a fresh survey be conducted.
Objections have also been raised by various sections of society, and there are also strong voices against it from within the ruling Congress.
Asked about differences among Ministers in cabinet, Jarkiholi cited an example of discussion on the population of Sadara community, which is shown at 65,000 and said some Minister pointing at the community's presence in districts of Haveri, Davangere, Chitradurga, also partly in Shivamogga, objected to the numbers; while some Ministers trying to clarify said many from the community have registered as Hindu-Sadara during the survey, and they have been considered under different category, which my has resulted in fall of the population number.
Such things are there and time is needed to match and discuss all this, also experts and the community's opinion needs to be obtained, he said.
Noting that the survey has recommended increasing reservation, Jarkiholi said to implement it there is already a stay from the Supreme Court in connection with Tamil Nadu's case.
"So enhancing reservation may not be possible as of now. For now the challenge before us is rectifying the data... opportunity should be given to rectify, if people want to opt for being considered under a different category or with their original major community, it should be allowed," he said.
The survey has recommended hiking the OBC quota from the current 32 per cent to 51 percent.
By giving OBCs a 51 per cent reservation, along with the existing 17 per cent for SCs and 7 per cent for STs, it will take the state's total reservation to 75 per cent.
Pointing out that a number of castes have expressed reservation about the population data in the survey report, Jarkiholi said these concerns must be addressed to avoid any political repurcussions.
Food and Civil Supplies Minister K H Muniyappa said the cabinet will continue the discussions on the caste census and will take a decision to ensures that no community is affected.
"There would be no problem for oppressed communities or Vokkaligas and Veershaiva-Lingayats. The government is being run by all communities, and a decision will be done based on consensus," he added.
