Understanding Sound Limiters: An Essential Guide for Your Wedding or Event

We at FPM Music Management take great pride in auditioning, building, and managing some of the finest function and event bands in the South West. One crucial aspect of managing live performances is understanding the role of sound limiters.

In this blog, we’ll explore why these devices are becoming increasingly common and how they might impact your event. From ensuring compliance with noise regulations to protecting the structural integrity of historical venues, we’ll cover the essential reasons as to why noise limiters are necessary in certain scenarios. We’ll also provide practical advice on working with sound monitoring equipment to ensure your live music experience remains uninterrupted.

Whether you’re a bride, groom, or an event organiser, this guide will help you navigate the nuances of sound limiters. Read on to learn how to make the most of your entertainment within these noise constraints.

Seven Reasons Why Sound Limiters Are Used:

1. Compliance with the Environmental Protection Act 1990: To avoid excessive noise that could be considered a statutory nuisance, many UK councils now require limiters to be installed in venues as part of their entertainment licence or renewal process.

2. Adherence to the Control of Noise at Work Regulations: These regulations are designed to protect the hearing of venue staff. Sound limiters help to ensure noise levels do not exceed safe limits.

3. Protection of Venue Structure: For older or historically significant venues, sound limiters prevent potential damage from loud music, particularly from powerful bass vibrations that could affect the structural integrity of the building.

4. Neighbour Considerations: Many event spaces are situated in residential areas. Limiters help manage noise levels to avoid disturbing nearby residents and maintain good community relations.

5. Preservation of Acoustic Environment: In older buildings or echo-prone spaces, such as theatres or churches, noise limiters help to retain the venue’s acoustics and preserve the natural resonance of the space.

6. Insurance Requirements: Some insurance policies may require sound monitoring equipment to be installed, thus reducing the risk of claims relating to noise complaints or structural damage from loud music.

7. Improved Sound Quality: By setting a maximum level, limiters help to prevent distortion and maintain a clearer audio experience. This ensures the music is enjoyable without overwhelming the space or causing unpleasant auditory effects.

Here at FPM Music Management, we ensure all bands under our stewardship are expertly trained in navigating venues equipped with these devices. Our musicians are skilled in adapting their performance to meet noise constraints. Additionally, we offer a range of acoustic acts and smaller-sized bands, providing flexible options for events that require a more tailored sound experience.

Whether you want an eight-piece ensemble or a more intimate three-piece lineup, our diverse range of South West-based wedding and event bands are prepared to deliver exceptional performances while respecting venue regulations.

Wedding & Event Sound Limiters: FAQs

What is a sound limiter?

A sound limiter is a device that monitors noise levels using a microphone and measures them in decibels (dB). If the noise surpasses a pre-set dB level for a short duration (usually five to 10 seconds), the limiter temporarily cuts power to the sound equipment for about a minute.

What dB level are they usually set to?

At wedding venues, sound limiters are generally set between 90 and 100 dB. For perspective, 90 dB is about as loud as a motorcycle eight metres away, and 100 dB is similar to the noise from a power lawn mower or a motorcycle up close.

How loud is a live band?

Most bands play at sound levels between 95 and 102 dB, depending on their size and the instruments used.

Is 95 dB loud enough?

A 95 dB limit might not be sufficient and could trigger the sound limiter. Discuss the specific limits with your band or DJ for tailored advice based on their experience. Remember that guest noise, such as singing or shouting, will also contribute to the overall level.

How high does the sound limiter need to be set for FPM?

Ideally, a minimum of 95 dB. If the dB limit is set to 94 or below, it’s unlikely our musicians will be able to perform effectively. Such a low limit restricts the volume, sapping the energy from the music and diminishing the overall experience. While we always strive to work within venue constraints, a dB limit this low significantly hinders our ability to deliver a high-quality performance.

How do bands adapt?

Experienced bands are familiar with sound limiters and will adjust their performance accordingly, typically lowering the PA volume. For acoustic instruments like brass and drums, which can’t be electronically adjusted, solutions may include using plastic drumsticks, heavy dampening or electronic drum kits.

How can I find out if my venue has a noise limiter?

Before booking, it’s a good idea to ask your venue manager or event coordinator whether one is installed. They can provide specific details about its settings and any restrictions. If you’ve already booked, review your venue’s contract or event information for mentions of sound limitations. Some bands may decline a booking if the venue has a sound limiter installed, so it’s essential to ask and double-check with your venue to ensure there are no surprises.

What happens if the limiter is triggered during the event?

When the device is triggered, it temporarily cuts power to the sound equipment, usually for about a minute. This can disrupt the music and affect the flow of your event. To minimise the risk, discuss the limiter’s settings with your band and plan for possible interruptions.

Can they affect the quality of live music?

Yes, sound limiters can affect how the music sounds, especially if it’s set too low. Bands may need to adjust their performance to stay within the noise constraints, which could impact the overall volume and energy. Furthermore, live music often relies on dynamic range - the contrast between the quiet and loud parts. Noise restrictions can affect the dynamics, potentially making the performance sound flat and less engaging.

How can I ensure my band are prepared?

Communicate any venue sound restrictions to them as early as possible. Experienced bands will know how to adapt their setup and performance to comply. It’s also helpful to visit the venue in advance and discuss the limiter’s settings with the manager.

What should I do if my venue doesn’t have one, but they’re still concerned about noise levels?

If your venue doesn’t use a limiter but is still concerned about noise levels, discuss alternative solutions with them. This could include adjusting the band’s volume, scheduling breaks to manage noise, or using sound-absorbing materials to reduce the overall impact.

Do they affect different types of music?

Different music genres can be affected by sound limiters. For example, genres with heavy bass, like electronic or rock, might trigger the limiter more often compared to acoustic or classical music. Bands specialising in genres with lower sound levels may have an easier time adapting.

Can sound limiters affect the performance of DJs or recorded music?

Yes, they can also impact DJs and pre-recorded audio. DJs may need to manage their volume levels carefully to avoid triggering the limiter. They might also use equipment that allows for better control of bass frequencies to stay within the limits.
