March 3rd: World Hearing Day

Have you ever noticed that the number 3 looks like an ear? It's no coincidence that the World Health Organization chose March 3rd to celebrate World Hearing Day each year. Since 2007, this campaign has aimed to share information and promote action to prevent hearing loss and improve hearing health worldwide. Every edition carries a different theme, a sign that the subject is broad and that there's no shortage of angles to explore.

One day, one ear, one message

Each year, the WHO selects a specific theme to address different aspects of hearing health. Over the years, campaigns have tackled noise prevention in recreational settings, universal access to care, the need to shift attitudes around deafness, and the importance of early screening. In 2022, for instance, the campaign "Make listening safe for life!" introduced a global standard for safe listening in entertainment venues and events. These are themes that, for anyone who works in sound, tend to hit pretty close to home.

2026: childhood at the center of the conversation

This year, the WHO's message is clear and targeted. The chosen theme is "From communities to schools: hearing care for all children." Behind that phrase lies a troubling reality: nearly 90 million children and adolescents between the ages of 5 and 19 live with hearing loss around the world. Most of them receive neither a diagnosis nor any treatment, particularly in low-resource countries.

What makes the situation even more frustrating is that, according to the WHO, 60% of these cases are preventable through straightforward measures such as vaccination, newborn screening, treatment of ear infections, or protection from loud noise. In other words, a large part of the problem is fixable — as long as we act early enough.

Schools as a turning point

Schools are identified as strategic entry points for raising awareness, screening, and referring children to appropriate care. That's where so much of it plays out, often without anyone realizing it. Undetected hearing loss in a child can look like inattention, restlessness, or unexplained difficulties in class. Untreated hearing loss can lead to social withdrawal, behavioral issues, and lack of focus — signs that parents and teachers sometimes incorrectly attribute to other causes.

The most common causes of hearing loss in children — such as otitis media with effusion, chronic suppurative otitis media, or earwax buildup — are frequent but treatable. Left unaddressed, they can have a significant impact on speech, language, cognitive development, and social skills, often leading to lower academic performance and long-term economic disadvantages.

An issue that goes beyond medicine

For someone who works with sound every day, this observance carries a particular weight. Hearing isn't just one sense among many — it's the connection between a person and the sonic world around them, between a child and the voice of their parents, between a student and the voice of their teacher. Hearing plays a central role in communication, education, employment, and well-being, yet more than 1.5 billion people worldwide are estimated to live with some degree of hearing loss, a figure that could reach 2.5 billion by 2050.

The campaign aims to turn teachers, healthcare workers, and families into frontline observers, able to spot early signs and point children toward the right services. It's a grassroots approach, grounded in daily life, and that's exactly why it feels right to me.

What each of us can do

The WHO encourages everyone to take steps to protect their hearing from loud sounds, get their hearing checked regularly, use hearing aids if needed, and support people living with hearing loss. Simple actions, often obvious, yet ones we tend to put off. We don't wait until we have a toothache to see the dentist — yet many people wait years before consulting a specialist about hearing decline.

Sounds below 80 dB are generally considered safe. For those without a sound level app, there's a simple rule of thumb: if you have to raise your voice to be heard by someone standing right next to you, the ambient noise level is probably too high. In concert venues, studios, and on set, that rule applies just as much to audio professionals as it does to any listener in the crowd.

What about you — have you ever had your hearing checked, or like a lot of people, do you keep putting that appointment off?
