Sound limits
in French venues

Jump straight to:

You have found the château. The photographs are extraordinary, the terrace opens onto a park, and the contract says the music can go until four in the morning.

Nobody has mentioned the small grey box on the wall behind the bar.

Roughly three French wedding venues in ten have a sound limiter. It is a device that measures the noise level in the room, and depending on how the venue has set it up, it can flash a warning at you, or cut the power to the DJ booth entirely. This page explains how it works, what it does to an evening when nobody saw it coming, and the six questions that settle the matter before you sign anything.

It is written by an English-speaking wedding DJ who has worked in 235 reception venues around Paris, and who has watched the power go out in the middle of a first dance.

Three venues in ten

A sound limiter is a small unit wired between the mains supply and the sound system. A microphone somewhere in the room feeds it a continuous reading of the noise level. When that reading goes past a threshold the venue has set, the limiter reacts.

If you are planning a destination wedding in France from the United States, this will be new to you. Sound limiters are close to unknown there. In the United Kingdom they are common enough that most couples have heard of them, though usually in the context of a village hall rather than a château.

In France they exist because of a specific piece of law. A 2017 decree on amplified sound applies to every venue open to the public, indoors and out. It obliges venues that regularly host amplified music to commission an acoustic impact study, and that study can conclude that a limiter is required. The device is not a whim of the owner. It is the outcome of a survey of what the neighbours can hear.

Which is why nobody, including us, can tell you whether your venue has one. Only the venue can.

The four warnings, in order of severity

Not every limiter behaves the same way. There are four responses, and they escalate.

A red light starts flashing

The mildest version. A lamp near the booth turns amber, then red. It tells the DJ he is over the line and gives him a few seconds to pull the level down. If your DJ knows the venue, he has already been watching it all evening.

A decibel reading on a display

Better, and the version we prefer. A live number on a screen means the DJ can see exactly where he is and work two or three decibels under the ceiling all night, instead of playing blind and discovering the limit by crossing it.

Someone from the venue comes to see you

A manager, an on-site coordinator, or the owner walks over and says it is too loud. Straightforward, and it usually happens once.

The power to the DJ booth is cut

The one that damages an evening. After a few seconds in the red, the limiter kills the electrical circuit feeding the booth. Everything stops. Sound, lights, the lot.

It comes back after ten, fifteen, twenty seconds. That does not sound like much written down. Stand in it and it is very long indeed: a room in the dark, no music, a hundred people shouting, and the couple in the middle of the floor not knowing whether to keep dancing.

We have worked an evening where that happened four times.

It is not the speakers. It is your guests.

This is the part that surprises everyone, and it is the reason a limiter cannot simply be solved by turning the music down.

The limiter measures the noise in the room. Not the output of the sound system. The microphone hanging from the ceiling cannot tell the difference between a speaker and a hundred people singing along to the chorus.

A DJ can set his system to a fixed level and hold it there all night. He can be three decibels under the threshold and never touch the master. And the limiter will still trip, because the guests are on their feet, singing, clapping and shouting over the top of the music.

Read that again, because it has an uncomfortable consequence. The better your evening is going, the more likely it is to be switched off.

The quiet weddings never have a problem with the limiter. It is the ones where the floor is full at one in the morning that find out the box exists.

90, 96 and 102

Three numbers explain the whole situation.

Level	What it is
102 dB(A)	The legal ceiling in France, measured over 15 minutes. Concert and festival territory.
94 to 96 dB(A)	Where a wedding dance floor actually works.
90 dB(A)	Where a great many venue limiters are set.

The law is not your problem. You will never approach 102 at a wedding. The gap that matters is the one between 96 and 90.

Six decibels sounds like a rounding error. It is not. Perceived loudness roughly halves for every ten decibels you lose, so a room capped at 90 rather than 96 loses around a third of its apparent volume. It is the difference between a floor that carries itself and a floor where people can hear their own conversations over the music, which is precisely when they go back to their table.

And there is no national figure. The threshold comes from each venue own acoustic study, which is based on what its particular neighbours can hear. A château surrounded by fields and a manor house with a hamlet at the end of the drive will not be set the same way, even if they look identical in the photographs.

The six questions to ask before you sign

This is the useful part of this page. Send these to your venue in writing, and keep the answer.

1. Is there a sound limiter? If the answer is no, ask whether there is any other noise restriction. Many venues have a curfew without a limiter.
2. What is it set to, in decibels? A venue that cannot tell you the figure has not read its own acoustic study.
3. What happens when it trips? A warning light, a display, or a power cut. This single answer changes the whole risk.
4. If it cuts the power, which circuit stays live? There is almost always a protected socket. Knowing which one, before the day, is the difference between a ten second silence and a five minute one.
5. Who from the venue will be on site on the night, and until what time? If the limiter trips at half past midnight and the last member of staff left at eleven, nobody can reset anything.
6. Has a wedding here ever had its power cut by the limiter? Ask it plainly. The answer, and the way it is given, tells you a great deal.

A venue that answers all six clearly is a venue that has thought about it. That is worth knowing before you pay a deposit, not in June.

And if your venue is one of the 235 we have already worked in, you can skip the email. Send us your date and the name of your venue and we will tell you what we found there.

Curfews and closed windows

A curfew is not a limiter, and the two get confused constantly. A limiter caps how loud you can be. A curfew caps how late you can be loud at all. A venue can have one, both, or neither.

What we see, across 235 venues:

• Most châteaux and country estates: music until four in the morning. This is the standard, and it is what most weddings do.
• Venues with housing nearby: two or three in the morning.
• Private mansions and palace hotels in Paris: one thirty or two in the morning, because they are hotels and people are asleep upstairs.

That last line matters if you are dreaming of a wedding in the centre of Paris. The address you choose for the view is also the address that decides when your evening ends. Our page on the 235 venues we already know lists what we have learned in each of them.

The doors and windows close at midnight

Here is the restriction nobody warns you about, and it is common.

Around midnight, one in the morning, or two depending on the venue, you will be asked to close the doors and the windows so the sound stays inside the building and does not travel to the neighbours.

Picture what that does. You had imagined a summer night with the french windows open onto the park, guests drifting between the dance floor and the terrace, smokers coming and going. From midnight, the room is sealed. The circulation changes, the smokers have to go the long way round, and the room gets warmer.

It is not a disaster. It is simply something to know in March, when you are still choosing between two venues, rather than at midnight on the night.

Choosing a venue at the moment? Our page on the 235 venues we already know tells you what we learned in each of them, and what actually fills a dance floor when half your guests do not speak French.

What about a silent disco?

Search this problem in English and you will be sold silent discos as the answer. Headphones for every guest, no noise in the room at all, no limiter, no curfew.

It works, technically. We do not recommend it, and here is the honest reason.

A dance floor is a collective thing. What makes it work is that a hundred people hear the same song at the same second, look at each other, and react together. Put headphones on everyone and you have a hundred people dancing near each other rather than with each other. The people not wearing headphones see a silent room of strangers moving oddly. Older guests take theirs off after two songs and do not put them back on.

If your venue truly makes real sound impossible after a certain hour, it is better than nothing and it will save the end of your night. As a plan for the whole evening, it costs you the thing you were trying to buy.

What this changes when you choose your DJ

None of this can be improvised on the day.

A limiter changes the equipment that makes sense in that room, where the speakers go, and how the level is set from the first song rather than the fortieth. It is worked out in advance, from the venue answers to the six questions above.

Our own terms and conditions say plainly that we are not responsible for the presence of a sound limiter and that it can affect the performance. That is not a way of stepping back from the problem. It is there because the honest answer is that no supplier can promise around a device they do not control, and any supplier who tells you otherwise has not met one.

What we can do is know the venue beforehand. Of the 235 reception venues we have worked in, we know which have a limiter, roughly where it is set, and which socket survives. That knowledge is not clever. It is just the accumulation of having been there before, and it is the whole reason this page exists.

Your questions, answered

Can the venue turn the limiter off for our wedding?

Almost never, and you should be wary of a venue that offers. The threshold usually comes from an acoustic study tied to the venue authorisation to operate. Disabling it is the venue risk to take, not yours, and the consequence lands on them long after your wedding is over.

Is 90 decibels really too quiet for a party?

It is workable, but it is tight. A dance floor sits comfortably at 94 to 96. At 90 you can still fill a floor, particularly in a room with good acoustics and a low ceiling. You feel it most in a big stone hall, where the sound has a lot of space to disappear into.

Do we have to pay a music licence fee in France?

No. Your DJ handles that side of it. It is not a cost that lands on a couple getting married.

Our venue has no limiter. Are we safe?

From a power cut, yes. You can still have a curfew, a noise clause in the contract, and neighbours entitled to call the police. Ask questions one and five anyway.

What time do French weddings actually finish?

Four in the morning is the usual answer at a château or a country estate. One thirty or two in a Paris hotel. Guests from abroad adapt to this far better than couples expect: we have run weddings for American, British and Australian couples that ran to four without anybody flagging.

Can you host the evening in English?

Yes. Announcements, introductions of the speeches, the whole evening if you want it, in English or in both languages. Details on our wedding DJ page.
