March 3 is world listening day. The World Health Organization issued the first “world hearing report” on the same day, warning that by 2050, nearly a quarter of the world’s population will “lose hearing” to varying degrees. According to the report, by 2050, nearly 2.5 billion people (25% of the world’s total population) will have varying degrees of hearing loss. If no action is taken, 700 million people will need to rely on rehabilitation services such as otology and hearing care.

Not only that, “hearing loss” will have a serious impact on people’s communication, learning and earning ability, but also affect their mental health.

The good news is that hearing loss can be reduced by early detection and early intervention. The report shows that nearly 60% of children’s hearing loss can be prevented by vaccination against rubella and meningitis, improving maternal and neonatal care, screening and early management of otitis media. As for adults, we can maintain good hearing and reduce the possibility of hearing loss by controlling noise, ensuring hearing safety, monitoring ototoxic drugs and paying attention to ear hygiene.

The World Health Organization has issued seven practical tips for “safe listening”: first, use earphones no more than 40 hours a week and keep the volume within 80 dB as far as possible; second, wear earplugs in noisy places such as dance halls, bars and sports events; third, use noise reducing earphones in noisy environments such as trains to reduce our demand for increasing the volume; fourth, use earphones in noisy places such as dance halls, bars and sports events, Monitor the time and volume range of using headphones, so as to be aware of the safety of listening; fifth, limit the daily use of personal audio; sixth, limit the activity time in noisy places and keep a distance from the loud sound source, such as going to a quiet place to let the ear rest for a short time; seventh, do hearing check regularly.

Once hearing loss occurs, early detection and early intervention is the key to rehabilitation. The report points out that current medical methods can cure most ear diseases and reverse related hearing loss. If the hearing loss is irreversible, rehabilitation services can be provided to ensure that the affected people avoid the adverse consequences of hearing loss. There are a series of effective hearing technologies, such as wearing hearing aids or cochlear implant hearing aids. There are also hearing aids and services for the deaf, which can further improve their communication and educational difficulties.

But at the same time, in most countries, ear and hearing care has not been included in the national health system, and it is difficult for patients with ear diseases and hearing loss to obtain health care services. In low-income countries, about 78% of the population have less than one ENT specialist per million; 93% have less than one audiologist per million; only 17% have one or more speech therapists per million; and 50% have one or more teachers for the deaf per million. Even in countries with a high proportion of otologists and hearing care professionals, the distribution of experts is unequal. This has not only brought challenges to the people in need of care, but also caused heavy pressure on the institutions and personnel providing these services.

The director general of the World Health Organization, Mr. tandesay, called for countries to encourage evidence-based interventions on hearing problems to be integrated into their health systems as part of universal health coverage. BENTE Mikkelsen, director of the Department of non communicable diseases of who, pointed out that a comprehensive people-oriented approach should be implemented. As part of universal health coverage, ear and hearing care measures should be integrated into national health plans, and interventions should be provided through a strong health system, “which is essential to meet the needs of people at risk of hearing loss or living in difficulties.”.
