This is what damaged hair cells sound like. A ringing that can come and go, or stay constant 24/7.

The ear has no "recover" button

Deep in your inner ear: 16,000 hair cells that transform sounds into nerve signals. Exposed too loud for too long, they die. Forever.

"Hidden hearing loss" — the invisible loss

You pass the hearing test — normal result. Yet you struggle to follow a conversation in noise. Millions are affected, without knowing it.

After a party, have you ever experienced any of these symptoms?

Time matters as much as volume

Every +3 dB halves the safe exposure time. And in a small room, wall reflections add 5–10 dB to what you actually receive.

The Solution

To double your safe listening time, you have two options: move further away from the speakers, or wear earplugs to reduce the volume by at least 3 dB.

Their ears are more fragile. Forever.

The auditory system of a child under 12 is more vulnerable. And above all — they have a whole lifetime to accumulate exposures. Damage at age 6 adds up with everything else.

Recommended thresholds — 2h event
Adults91 dB
Kids 3–12 years80 dB
Babies 0–3 years · daycare70 dB

More conservative than adult standards — on purpose.

What you might be doing without knowing

A birthday with full Bluetooth = 85–90 dB. A school fair PA system often exceeds 95 dB at 5 meters. A 7-year-old in this zone for 2h receives a dose for which adults only have 30–60 min of tolerance.

  • Noise-canceling headphones for children at amplified events are not an exaggeration — they are a medically sound precaution.
  • End-of-year gym shows are among the most dangerous events: small room + PA system + babies present.
  • Explaining to children why ears ring — with the right words — makes them active participants in their protection very early on.

You're not alone in thinking it's too loud. The vast majority of guests don't dare to speak up for fear of ruining the mood, and end up shouting to talk to their loved ones or leaving the room. SoundTrust breaks this taboo: it's an anonymous, simple, and caring way to say 'It's a bit too loud' without any confrontation.
