The SoundTrust Initiative
Epic Parties. Safe Ears.
You plan the music, the venue, the atmosphere. SoundTrust asks for one thing more : that your guests — adults and children alike — leave with their hearing intact.
No equipment required. No administrative hassle. Three concrete actions — and a badge that shows you care.
The 3 simple actions
Generate your SoundTrust badge
Print this badge and display it at the entrance or bar, or integrate it into your invitations and flyers, to show your commitment, allow guests to discover the initiative, and simply report if the volume is too loud.

Kids' Parties
Birthdays and small parties. Often held in confined indoor spaces where noise echoes easily.
Solution: Lower the volume and create calm moments. Kids' ears are more sensitive.

Thresholds to Know
Across Europe, legal limits for amplified music typically range from 85 to 102 dB, varying by country and venue type.
The WHO recommends a maximum of 100 dB over any 15-minute window — not per evening.

iOS
The NIOSH SLM app (iOS) displays the average sound level of your event in real-time. Developed by the US CDC, it is free, ad-free, and scientifically calibrated.
Place your phone at ear level, 1–2 meters from the speakers. If the needle exceeds 85–90 dB — turn it down.
Android
On Android: DecibelX or Sound Meter by Splendo.
The illusion of volume
People often think that turning up the volume turns up the vibe. This is false. Beyond a certain threshold, the sound distorts, fatigues the brain (auditory fatigue), and isolates people. The best party is one where the music is clear and catchy, but where you can still share a joke with your neighbor.
Brief your sound team
Whether it's a DJ for a wedding or a sound engineer at a large event, let them know: 'We are using SoundTrust. The comfort of our audience is our priority. If you receive alerts, simply turn it down by 2 or 3 decibels—no one will notice the drop, but everyone will feel the relief.'
The SoundTrust initiative is primarily about public health awareness and the quality of your events. We want guests to be able to talk and enjoy themselves without ruining the party or imposing formal constraints.
How it works
Note: True commitment goes beyond hardware. Venue directors often claim they have automatic decibel limiters, but these are frequently unplugged. Similarly, 'hush parties' (silent discos) are a good alternative, but they tend to isolate guests instead of creating a shared experience. Real change comes from the active commitment of organizers to maintain a reasonable volume for everyone.
